Herschel11638

From:
M. Macann
To:
Sir John Herschel
Date:
[19 April 1848]
Source of text:
RS:HS 12.3
Summary:

Has heard no more news of his paper; shall he write to the R.S.L. for news? Comments on the claims of James MacCullagh for theories regarding light. Hopes to get something published by the London publishers so has written a paper on trigonometry, which he hopes JH will present to the R.S.L. Doubtless JH is aware that there is no general proof for John Napier's rules.
