Morton-Wall: Science Contrarian review (Step 2)

Reviewer: Science Contrarian. Date 2026-10-08. Inputs read: claims.md, facts.json, the deep read, sites.md (Leads) and research notes, and primary text myself: Houston 1871 (project PDF text layer; independent copy in Scientific American 10 June 1871, research/files), Houston Jan 1876 (research/files), Wahl 1871 (text layer and page images pp.320-321), Woodbury 1944 (pp.63-65). Tags: [read] source text; [web] URL; [memory] with confidence.

Source gap: none for the two articles (text is good). Not read: Thomson's notebooks and 1922 recollections (APS), Brenni 2015, Susskind 1964 (paywalled), Atherton beyond the Investigator's quote, German abstracts. Conclusions about authorship and about "waves" rest on the published record only.

Corrections to Step 1 (and earlier documents)

1. Wahl's coil figures were mis-OCR'd; claim 5 is wrong as stated. claims.md claim 5, facts.json (Wahl entry) and the deep read give "443 miles of secondary wire", "about 444 miles", "443 pounds", "825 sq ft" of condenser foil and primary wire "0.1635 in". The page images show different numbers. [read: page image p.320] "containing but 44⅓ miles of wire, 40 inches in length, and weighing about 250 pounds". [read: page image p.321] "secondary wire is 234,100 feet, or about 44½ miles ... weighs 44½ pounds"; condenser "325 square feet of tin foil"; primary "0·1655 of an inch". Check: 234,100 ft / 5280 = 44.3 miles, so the scan is self-consistent and the OCR "443/444" is a dropped fraction sign. Consequence: Morton's coil had about one third of the wire of the London (App) coil (150 miles) yet gave 21 in sparks from three cells against 29 in from about sixty cells. The "more wire, more reliable" contrast in Step 1 is inverted: the claim is "less wire, fewer cells, longer life". My own check of plausibility [calculation from Wahl's numbers]: 0.007 in copper wire, 234,100 ft, weighs about 35 lb bare (density 8.9 g/cm3), consistent with 44½ lb silk-covered; 443 miles would have needed about 350 lb, more than the 250 lb coil. The old numbers fail Wahl's own totals; the new ones pass.
2. claims.md claim 1 and facts: the lecture table was not an insulated conductor. [read: Houston 1871] the second pole "was connected with a wire, which rested on a large lecture table"; Houston says the table is only "in partial connection with the earth ... for several gas and water pipes are in connection with the table". So in arrangements 1 and 2 both poles had a leaky path to earth. Only the tin-still arrangement used an insulated conductor. Step 1 words ("large, imperfectly insulated conductor") are fair; the reader must not picture an antenna on glass for the table and stove cases.
3. The five-inch spark belongs to the neither-pole-earthed arrangement. [read: Houston 1871] the conductor was "divided into two ... connected with the poles"; the five-inch spark came when one of the two was under one square foot. claims.md claim 3 mixes this with the one-pole-earthed case. The two-conductor result is a different circuit (both poles on floating conductors).
4. Claim 2 path to the engine is partly answered by Houston 1876. [read: Houston 1876 p.60] the half-horse engine and the boiler below were "in metallic connection with the water-pipes"; the pneumatic trough was joined "by soldered joints with the water-pipes". Step 1 said the path "is not described". For 1871 it is not stated in the note itself, but the inventor's own later account makes a conducted path through the building's pipes the stated situation. Not in the 1871 note: knife-blade sparks from gas burners (1876 only).
5. Investigator's battery note needs a caution (sites.md "Corrections"). [read: Houston 1876 p.60] the 1875 text says "One pole of the battery was placed in metallic connection with a gas pipe and the other ... with a large insulated conductor", and the sparks "passed between the platinum points of the coil". Literally this puts the pipe and conductor on the battery (primary) side, and "platinum points" are normally the interrupter contacts. The Investigator reads it as the secondary poles by context; that is plausible (the note refers back to the 1871 arrangement) but the wording is ambiguous and I cannot settle it. It matters: grounding the primary supply is a different circuit. The "ten-cell electro-poion battery" is, in any case, for December 1875, not 1871.
6. Woodbury (1944) is not an independent witness to 1871 details. [read: Woodbury pp.63-64] his 1871 story contains "the frame of a steam engine fully 30 feet away", "light a gas burner" (both in Houston 1871) and a "knife blade" (in Houston 1876 only), and says the jar sparks turned "vivid blue" where Houston says "silvery white". It reads as Thomson-side retelling that overlays published text. His claim that Houston "took sole credit" is his characterization (a Thomson biography, written with a stake in Thomson's credit) and is not corroborated by Thomson's own words that I could read (Thomson's 1902 recollection in Edmonds does not mention the coil work [read, per Investigator]). It stays in the record as the only account assigning the 1871 observations to Thomson.
7. Minor: facts.json says no "Ritchie" statement links Houston's 6-in coil to Wahl's 21-in coil; agreed. Houston's coil is a different instrument.

Common ground rules I apply

• The two articles claim only observations and a qualitative explanation. Neither claims excess energy. The "radiant energy / scalar wave" reading belongs to forum and free-energy authors (Energetic Forum thread, Kelly's chapter 5) and to some historians reading "wireless" (Woodbury, Atherton, Susskind); Houston's own explanation (1871 and 1876) is condensation plus induced currents.
• Standard physics I use (all [memory, high] unless stated): a conductor connected to one terminal with the other terminal earthed is a capacitor C in parallel with the gap; the spark is the discharge of the secondary's own capacitance plus C; energy per discharge is about ½CV². Long-spark voltages: [web] https://en.wikipedia.org/wiki/Induction_coil gives 4 in about 110 kV, 8 in about 150 kV (citing a 1914 source); an empirical formula quoted on a Tesla mailing list gives about 230 kV at 6 in (pupman.com archive via search). So a six-inch spark is roughly 100-200 kV; I use 100 kV as an order of magnitude.
• Worked size: an isolated sphere has C = 4pieps0*R (eps0 = 8.85e-12 F/m). One square foot (0.093 m2) is a sphere of R = 8.6 cm, C about 9.6 pF; "several hundred" sq ft (say 300 sq ft = 28 m2) is R = 1.5 m, C about 170 pF (a flat sheet somewhat more). At 100 kV, ½CV^2 is about 0.05 J (1 sq ft) and about 0.8 J (300 sq ft). A 14 sq ft Leyden jar (1.3 m2 of foil on glass perhaps 2-3 mm thick, k about 6, [memory, medium]) is roughly 25-35 nF, about 100 to 1000 times the isolated conductors. That is why Wahl's jar gives 2-in sparks and Houston's stills only "shorten and whiten".

Claim 1. One pole earthed (gas pipe), other on a large leaky conductor (lecture table): spark thicker, shorter, silvery white, like a Leyden jar in circuit

a. Maths: no equations in Houston. Qualitative statement is internally consistent. The frictional-machine analogy is loose (earthing a machine conductor supplies charge from the earth; here the earth is the return path), but nothing contradicts itself. b. Experiments: consistent with Morton 1867 [read: research/files JFI 1867, pp.256-260]: a jar "shortens the spark and increases greatly its brightness" with "white light and loud report". Also with Wahl 1871 (jar, secondary condenser). A conductor-to-earth path is a shunt capacitor; effect is expected. c. Tested: observed by Houston 1871; repeated Dec 1875 with Thomson (same institution, not independent); described again in Houston 1876. Woodbury says Thomson, using jars first, made the table-and-pipe substitution; Thomson's own notes unread. No neutral third party. d. If true: nothing changes; it is ordinary capacitive loading.

Verdict: Established (qualitative appearance and trade-off), as a recorded observation consistent with Leyden-jar practice; no measurement of any kind. Not an anomaly.

Claim 2. Sparks drawn from metal 8-9 ft away, from a stove, a steam engine "fully thirty feet" away, a wire in a room below, a person's finger lighting gas

a. Maths: none given. b. Experiments: matches ordinary electrostatic and transient-current effects near a spark-gap coil: isolated metal in a rapidly changing field charges through capacitance and sparks to a grounded or approached object; metal joined to pipes carries the transients. Houston 1876 states the engine, boiler and trough were "in metallic connection with the water-pipes" [read]. That makes the 30 ft a conducted path along pipework, not free-space action. It matches Edison's 1875 "etheric force" sparks, independently found with a different arrangement, which Edison reported at "twenty to thirty feet" [web: https://en.wikipedia.org/wiki/Etheric_force, citing Israel, Wills]. c. Tested: observed by Houston; Dec 1875 repeated with Thomson and tested with electroscope, astatic galvanometer, cotton wool, "retro-action" [read: 1876]; Woodbury names Prof. Monroe B. Snyder as a witness drawing sparks from a rooftop observatory "90 feet" above the coil in 1875 [Investigator; Woodbury]; Edison's team saw similar sparks independently. No record of a field measurement. Snyder joined the staff in 1873, so he could not have witnessed 1871 [Edmonds, via Investigator]; his account is a single published source (Woodbury), and Thomson's 1932 tribute might hold it. d. If true: nothing. If it were a free-space radiated wave (reading of Susskind, Atherton, Woodbury) it would be pre-Hertz radio, historically significant but not a change to Maxwell's theory (predicted 1864 [web, same Wikipedia page]); Hertz confirmed it 1886-88 [memory, high].

Contrarian points: - The null tests of Houston and Thomson (gold-leaf electroscope, astatic galvanometer, cotton shred) are the right tests to show no steady charge or current, but a rapidly oscillating charge gives no net deflection, so they cannot exclude oscillation. They argue "induction", not "no radiation". Neither side measured fields, frequency or distance dependence. The critics of Edison were correct that it was no new force, and the phenomenon was, in modern terms, high-frequency electromagnetic and conducted transients; Edison was then pressured by Western Union to stop [web: Wikipedia Etheric force]. So the record here is "rejected as new, never characterized". - Radiated-wave reading: no data. A crude upper bound: 0.05-0.8 J per spark times a break rate of order 10-50 per second is under about 40 W of spark power total, and radiation is a small fraction. Near-field coupling and pipe conduction explain 8-30 ft without invoking radiation, but I cannot exclude some radiated component. - The "radiant energy" free-energy reading adds no measurement of energy output. Nothing in the sources reports more energy out than in.

Verdict (split): sparks near the coil, via pipework and induction: Established as observation and consistent with accepted physics (replicated within the same group, and by Edison's independent similar observation). That the effect is free-space wireless transmission or "radiant energy": Never properly tested (neither confirmed nor refuted; the contemporary tests did not address it; not dismissed without testing for the induction explanation, but the wave question was not asked).

Claim 3. Large insulated conductor on one pole, or one on each pole, raises "quantity"; shrinking one conductor below about one square foot restores a spark of about 5 in without sensible loss of quantity

a. Maths: none. "Quantity" is undefined in modern terms (charge per spark? energy per spark? brightness?). [read] Houston judged it by eye ("fine quantity spark"). Within its meaning, consistent: more capacity gives shorter, fatter sparks (Houston's own result), smaller capacity gives longer sparks. b. Consistent with Morton 1867 and Wahl 1871: single jar shortens, cascade (series) jars lengthen [read]. Series capacitance C/n explains why Wahl's 20-pane cascade condenser gave 14 in against 2 in for one 14 sq ft jar. c. Tested: once, qualitatively, by Houston; no measures, no repeats, no dates, no battery. Houston gave no spark lengths at intermediate steps. No replication of the 5-in result is on record. d. Nothing.

Hard criticism of the inventor: "without any sensible diminution in quantity" is unfalsifiable as written; no galvanometer, no heating, no perforation, no photometry. A 6 in free-air spark, with 5 in obtained at under one square foot (C about 10 pF, comparable to the coil's own terminal capacitance), is what one expects from a small added capacity.

Verdict: Never properly tested (a clear observational report, no measurement; not dismissed, simply not followed up quantitatively).

Claim 4. Explanation: the large conductor allows rapid discharge, hence rapid induction in the secondary, as when a frictional machine's conductor is earthed; maximum at several hundred sq ft on one pole with the other earthed

a. Maths: not mathematical. The sentence "the table ... allows the rapid induction of electricity in the secondary wire by its rapid discharge" is hedged ("probably", "it would seem") and in its literal form is not consistent with energy accounting: the secondary cannot gain energy from the conductor; what changes is how the stored energy is released (one fat discharge instead of a thin one). Houston's 1876 version is better and is the inventor's own correction of the language: "condensation of the spark by connection with extended surfaces, similar to ... a Leyden battery" [read]. b. Experiments: the condensation reading agrees with Morton 1867 and Wahl. The "maximum at several hundred sq ft" extrapolation is contradicted by Houston's own data in the same note: more capacity gave "great diminution in the length". Beyond a point the voltage across the gap cannot rise to breakdown, so there is an optimum, not a monotone gain. Not tested. c. Tested: the several-hundred-sq-ft arrangement was never built [read]. Houston and Thomson's April 1876 tests concern Edison's sparks (balanced battery, paired magnets, coated test tube), where the Leyden-coating analogy is applied; those support the capacitor language but do not test the 1871 maximum. d. Nothing changes; the explanation is within circuit theory.

Verdict (split): condensation / extra-capacitance mechanism: Plausible, untested (as a quantitative account; accepted in kind). "Rapid induction by rapid discharge" in its literal form and the "maximum at several hundred sq ft" prediction: Never properly tested, and the second is contradicted by the same paper's trade-off, so likely wrong as a monotone claim.

Claim 5. Ritchie's coil for Morton (corrected: 44⅓ miles of secondary, about 250 lb) gives 21 in sparks from three bichromate cells more reliably than a larger London coil (29 in, about sixty cells, failed)

a. Maths: with corrections to Step 1 the numbers are consistent (234,100 ft = 44.3 mi; wire mass fits). My rough turns estimate from Wahl's data: secondary about 234,100 ft over turns of about 1.9 ft (bobbin 9 in, estimate) gives about 120,000 turns; primary about 200 ft gives of order 150 turns; ratio near 800 (my estimate). Three cells (about 6 V) give an open-circuit EMF of order a few kV from the steady ratio alone; the spark voltage (21 in is more than 200 kV by the same tables) comes from the inductive kick at break, which depends on the 325 sq ft condenser and primary current, neither given. I cannot confirm 21 in from the stated data; it is not implausible given Ritchie's reputation, but unverified here. b. Experiments: consistent with other long-spark coils of the period [memory, medium: Spottiswoode's later coil; Brenni 2015 as a historian's treatment, not read]. The 29-in App coil "soon failed" is Wahl's report ("we understand"). c. Tested: Wahl's own description, of an instrument owned by his co-editor Morton, who also supplied the battery design and told Wahl of lecture use. Interested-party description: Wahl and Morton were co-editors of the journal; the maker Ritchie is praised, and a rival's coil is described as a failure by hearsay. This does not make it wrong; it is one published source with an interest, and no independent test or measurement in the folder. Wahl promised "a future time we will give some further account"; the Investigator found none in JFI July 1871 - June 1872 (silence recorded; explanations: unwritten, published elsewhere, not done; Morton's papers at Stevens would decide). d. Nothing; it is engineering.

Verdict: Plausible, untested (as to independent verification of 21 in from three cells; engineering claim, not physics; no controversy).

Claim 6. Same coil: 2 in sparks with a 14 sq ft jar; 14 in with a 20-pane secondary condenser; coupling halves for "quantity" shortens the spark to 12 in; four half-gallon jars give "deafening" sparks

a. Maths: consistent. Jar in parallel across the gap: large C, short, loud spark; plates in cascade: series C is small, spark longer, still white and loud. Coupling coil halves in parallel halves the secondary inductance and raises current, shortening the spark: consistent with ordinary transformer behavior. b. Experiments: consistent with Morton 1867 [read]: single jar 1 in, six jars cascade 4 in, 8-plate cascade 5½ in with white light and loud report. c. Tested: Wahl's observations, no measurements beyond lengths, interested party as above; Morton's 1867 paper is the earlier published basis and is now in the record (it was marked missing in claims.md). d. Nothing.

Verdict: Established (standard spark-length versus capacity behavior; reporting is by an interested party but matches earlier independent literature).

Other pertinent items (kept whatever the verdict)

• Editors' note, Houston 1876: "whatever there may be remarkable in the phenomena of so-called Etheric Force, was described by Prof. Houston, previous to the discovery of Mr. Edison" (stake: the Institute's member's priority).
• Absence of evidence: no further coil-connection note by Houston between June 1871 and December 1875; Houston studied in Germany 1872-73 and Wahl substituted at Central High [Edmonds via Investigator]. Competing explanations: no further experiments, or published elsewhere. The Thomson notebooks (APS Mss.Ms.Coll.74) would decide.
• The Franklin Journal editors in the same volume treated claims of excess energy skeptically (Highton electromagnet claim answered by energy accounting; tinfoil test "no improvement whatever", [read: facts]). This is a hint that Morton and Wahl were open to testing claims; relevant to the 1870s rejection of Edison-type claims being by experiment-minded colleagues, though not by neutral testers of Houston's own claims (nobody tested those).
• Reading the claims as free-energy: nothing in the folder claims it; I would call that reading unsupported by data, not refuted by it.

How these claims were treated

Not dismissed without testing: Houston's observations were never challenged. Not tested rigorously either: no measurement of "quantity", no repetition outside the Houston-Thomson pair, no radiation measurement. Edison's parallel claim was rejected by experiments that were sound for the claim of "no charge" but could not address oscillation, and he was financially pressed to stop. Priority of authorship (Houston versus Thomson) is unresolved on the published record.

What would settle it

• Measure the spark with the same coil and known capacitances (calibrated capacitor, oscilloscope or voltage divider, calorimetric spark energy): "quantity" versus C. Predict an optimum C, not monotone growth.
• A loop antenna or spark-gap detector at 1, 3, 10, 30 ft with and without the pipe connection: separates conducted from radiated.
• Thomson notebooks 1871 and 1875 (authorship, battery, dates); Morton papers at Stevens (the promised Wahl account).

Summary of verdicts

1. Spark thicker, shorter, white with earth plus conductor: Established (qualitative).
2. Remote sparks 8-30 ft: Established as observation (conducted/induced); radiated or "radiant energy" reading: Never properly tested.
3. Quantity raised, 5 in spark: Never properly tested.
4. Mechanism: condensation: Plausible, untested; literal "rapid induction" and several-hundred-sq-ft maximum: Never properly tested (likely wrong as monotone).
5. Morton coil 21 in on three cells (44⅓ miles, corrected): Plausible, untested.
6. Jar and condenser trade-off: Established.
