To Asa Gray 2 March 1
My dear Gray
I have had very short but sharpish touch of illness,—a slight touch of pleurisy, & am weak.—but write just to thank much for letter received today2 (your two enclosed letters have been posted) & to say that in one week I hope & think I shall send you a few more rather important additions & expansions for the “Origin”. The first & most considerable one is for p. 126. If you can anyhow manage to get this inserted I shall be very glad— It is of some pages length.— There are a few of the most objectionable parts later in volume expanded a little.3 I am tired, so no more
Has been ill with pleurisy.
Sends more corrections and additions for American edition of Origin.
