3-15-38. George Howard Darwin to H. Poincaré

Oct. 19.01.

Newnham Grange–Cambridge

Dear Monsieur Poincaré,

I send you a copy of the Ellipsoidal Harmonics with nearly if not all the mistakes & misprints corrected.11endnote: 1 Darwin 1902.

I am very glad to hear yr paper is nearly finished.22endnote: 2 See Poincaré to Darwin (§ 3-15-37). As an F.R.S. you of course present yr paper in propriâ personâ (of course you need not be there in the body), but if you will allow it to pass thro’ my hands I should have an opportunity of glancing through it. I suppose it will be “read” on the same day as mine.33endnote: 3 The papers by Darwin and Poincaré were presented to the Royal Society on 21.11.1901. The reading of such papers is generally a very short affair but if I have had the paper I shd be able to say a few words as to its object & scope.

It is necessary to send an abstract (for the proceedings) which may range from a dozen lines to 3 or 4 pages as the author chooses.44endnote: 4 Poincaré 1901. If you find it too tiresome to write an abstract I will try what I can do, but author’s abstract wd naturally be much more satisfactory. My own paper has now gone back purged, I think, of its sins — for which yr last letter I think gives me absolution.

Yours Sincerely,

G. H. Darwin
