The Refraction Decision
An arc was observed over Tomb R.14 on nineteen mornings. The papers that followed do not explain it; they explain the decision to print the observation and keep interpretation apart.
Record path
From observation to editorial boundary
The Committee correspondence does not turn the phenomenon into proof of anything. It makes the editorial choice visible.
-
01
The arc was watched, not merely reported.
Dr. F. L. Ambrose records an optical appearance on nineteen mornings at the mouth of Tomb R.14. It appeared before sunrise and was no longer seen after 9 March.
Read the observed record
The Committee file preserves Ambrose's memorandum in full.
- Item /5 · Ambrose memorandum, p. 4 nineteen mornings; dates and watch
- Item /1 · Annual Report, p. 15 published refraction section begins
-
02
The figures resist an easy solar explanation.
On nine mornings the centre of the arc held at 284° within 1°30′, even while the sun's rising point shifted. The memorandum also records strong plane polarisation. These are measurements, not a theory of their cause.
Inspect the measurements
The relevant figures are preserved together in the enclosed memorandum.
- Item /5 · Ambrose memorandum, p. 4 bearing, polarisation, and the post-removal watch
- Item /1 · Annual Report, p. 16 the published technical account

Ravensworth asks whether the record belongs in print.
The Director tells the Chairman that an accurately observed fact should not be suppressed simply because its character is unusual. He also asks whether the Committee should attach its name to a passage likely to invite ridicule or credulity.
Read the Director's question
The letter introduces the Committee's later decision; it does not offer an interpretation.
- Item /5 · Director to Chairman, pp. 2–3 the case for retaining the observation
-
04
The Committee's concern is the meaning readers may supply.
A Committee member accepts Ambrose's figures, but worries that measurements printed beside the carved bow will be taken as an intended connection. The proposed remedy is to print the readings in their barest technical form and separate comparative matter.
Read the caution
The letter is cautious about reception, not dismissive of the observer.
- Item /5 · Committee member to Chairman, p. 5 the proposed editorial division
-
05
The decision is to preserve the fact and limit the claim.
The Chairman directs that the phenomenon be printed factually, in Ambrose's figures and substantially his own words. Comparative and interpretive material is to sit in a separate, clearly numbered appendix rather than in the Report's descriptive narrative.
Read the decision and its published counterpart
The documentary decision and the Report's structure can be read beside one another.
- Item /5 · Chairman to Director, pp. 6–7 the Committee's instruction
- Item /2 · Appendix I, p. 1 the separately printed comparative note
-
06
The division is part of the archive's meaning.
Read together, the Report, appendix, and Committee file document how a fact was retained without making the Committee responsible for an explanation. That editorial boundary is itself evidence; it is not evidence of what caused the arc.
Return to the published record
The path ends at the distinction the papers deliberately preserve.
- Item /1 · Annual Report the published observations
- Item /2 · Appendix I comparative material kept apart
- Item /5 · Committee Correspondence the decision behind the division
