Bromley Kent

Jan 7th 78

Sir

The Spermaceti Ointment supplied to you is made according to the orders of the British Pharmacopæa which are

Spermaceti 5 ounces

White Wax 2 ounces

Almond Oil 20 ounces or a sufficiency

Would the effects produced be caused by any-thing used in the bleaching the Bees’ Wax?1

The process used to be by exposure to air in thin ribands & in the end refined by melting in water acidulated by sulphuric acid, but what is the mode adopted now I do not know, but will inquire if you wish it.

Oil of Almonds differs but little in composition from Olive Oil containing more oleine & less margarine.2

With respects | Yrs obedly | Wm. W. Baxter

C. Darwin Esqre

Footnotes

See letter to W. W. Baxter, 6 January [1878] and n. 2. CD had asked about the composition of spermaceti ointment purchased from Baxter, a local chemist; it had apparently damaged some growing plants on which CD was experimenting. See British pharmacopœia (1877), p. 353.
Olein and margarin were terms for components of plant oils (see Dussauce 1869, pp. 171–2, OED).
