Summary:
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".
