Note 148 — XXII. (continued 2)
Reading edition
As, judging by the experiments hitherto made, cocain seems to consist of two atoms in juxta-position, there is reason to conjecture that it is destined to be the source of a large number of products of transformation. It is highly probable, as Wöhler has remarked, that cocain may yet be artificially made by a mixture of hygrin with Benzoic acid, or rather with one of the substances forming part of the Benzoyle group.
