Sends FD £5 for the loan of his microscope.
Sends to Pantlludw [North Wales] bottle of formic acid. FD and Amy [Darwin] can search for spawn. If found, keep in two basins and add 6 drops of acid to one and look for differences.
"Try only 1 or 2 drops of Formic A[cid]."
Fears all the seeds are dead. Will try with less vapour of formic acid.
Observations on bees’ biting holes in Lathyrus.
Suggests an experiment FD could carry out with Drosera.
CD is working on Mimosa, and "everything has turned out as perversely as possible".
Pollination and floral structure of Lathyrus. Asks where bees bite through the flowers.
Asks FD to bring any book that gives the affinities of the various earths, alkalis and metals.
Asks for details about microscope parts.
Wants FD to ask Hooker for species of Desmodium; CD believes he has found new movements.
Also ask whether Hooker has Drosophyllum.
Lists observations he would like FD to make on the dried species of Desmodium at Kew.
