Dear Father,

I send you a draft of a letter to Nature (with a wide margin for corrections)—if you think it worth while correcting yr former letter.—² And I think it is worth while, since everything you write attracts so much attention, that it is a pity to let people break their heads over your meaning. If you think of sending it you might have the proofs sent direct to me at Camb. & I w^d. take the trouble off your hands.³ I think the letter expresses your meaning clearly— if it does’nt it is’nt worth your while to bother more about it.

I have been down to Greenwich this m^g. to see Lenny & the observ^y.⁴ I am pretty well today tho’ I turn bilious every night.

Would you have sent to me by post (price 4^d I think) the Sausage of beef tea wh. I gave to M^rs. Evans just before starting.⁵ D^r. C.⁶ wishes me to give up meat & everything solid when I get right down bad—& as I never know when that may be I sh^d. like to have it by me.—

I asked D^r. C about Edmund⁷ & he said his meaning was that he c^d. never get well & that the only question was whether & for how long one c^d. keep things Stationary & not that he was in a galloping consumption. He thinks it w^d be wiser for him to go abroad for winter. I’m off tomorrow a.m.
