Has not answered CD's former letters. Has been ill. Will look up fish business as soon as he is square again.
My dear Darwin
I am glad you have received the monkey book and I shall be right glad of criticisms by & bye if you have any time to spare for them—
I am ashamed not to have answered your former letter but I fell ill on the Tuesday after you were with us—spent a day or so in bed and have not got right yet
As soon as I am square again I will look up the fish business
Ever | Yours faithfully | T H Huxley
