To J. S. Henslow 14 July 
Down Farnborough Kent
My dear Henslow.
With mistakes & alterations, the Hitcham list1 is so blotched, that I have copied out the 22 plants, which grow at Hitcham & are found at Azores; & are, according to a list of 77 received yesterday, from Mr H. C. Watson, the least likely to have been imported with agricultural seeds.—2 If you will employ your little girls to collect these, I shd be greatly obliged, & pay them liberally for me. I shd require, when such could be procured, a packet with 100 or 200 seeds of each kind, or even rather more of the easily procured kinds; of course less would do. But I have to try them without salting, & at successive periods after immersion.—
I think I shd prefer waiting till you have a good many of the 22 kinds together.
I hope that you think the experiment sufficiently curious to repay you in some slight degree for part of trouble you have so kindly taken. I hope that the little girls, with payment in view, will enjoy the job.—
Most truly yours | C. Darwin diag Water-cress— Nasturtium officinale
