Orders sulphuric ether, nitric ether, chloroform, and prussic acid [for Drosera experiments? See Insectivorous plants, pp. 209, 219].

Orders enema.

Would greatly prefer an enema with a shorter nozzle but with a somewhat larger diameter.

Asks about possible animal substances in samples of Belladonna and Digitalis.

Sends CD description of preparation of extract of belladonna.

Thanks for information about the Atropia.

Requests litmus paper and gum.

Orders list of chemical salts. Ashamed to order from Hopkins and Williams because they charge him such an extremely low rate.

Orders salts of various metals; thinks chlorides (where soluble) would be better than nitrates.

Requests chemicals for Drosera experiments. Lists 12 acids tried so far.

Requests 6 2oz bottles with corks. Folic acid produces remarkable effect. Orders hydriodic acid.

Requests hydrated magnesia.

Orders two bottles of chlorodyne and bottles and corks of various sizes.

Asks about the composition of a spermaceti ointment which he has been buying for some years "because I blackened some young shoots of plants with this ointment mixed with Lamp-black & it produced an extraordinary effect on the shoots, which I think cannot be accounted for merely by the exclusion of light".

Constituents of spermaceti ointment supplied to CD. Perhaps effect was caused by substance used to bleach the bees-wax.

Orders vaseline and pomatum – the latter to put on his beard, which in dry weather feels uncomfortably harsh.

Orders morphia pills in case of severe pain, which he hopes may never occur.

Orders two bottles of "the simple Antispasmodic" and "the Glycerin Pepsin mixture". Andrew Clark wishes him to commence his physic at once.
