Thanks for information about the weight of water.
Describes experiments on Drosera.
Down, Bromley, Kent
Upon my life I think you must be the most good-natured man in the world. How capitally you have answered the question about the weight of water; you are as good, indeed a great deal better, than an Encyclopedia. How fortunate for me that I asked you about Hofman's note. What a horrid blunder I should have made! But what trouble you have taken for me.— About the measure and weights I daresay your explanation is quite right, for I looked into old and new books; but there were also most stupid misprints.— I shall permanently keep your letter.
As you seem a little interested about Drosera, I may mention that today I have been
testing how light a weight will set a single hair moving, and I find
I have been much amused by your account of your conversation with Woodward and I should much like to hear you take him off. He is a very good man in his way, and his generalisations on Shells are really capital.
We returned home on Saturday evening; and my girl stood the journey well; but she is very weak.
With hearty thanks | Yours very sincerely | C. Darwin
