[2031] For a notice of them, see O’Shaughnessy, On the preparation of the Indian Hemp or Gunjah, Calcutta, 1839; also Bengal Dispensatory, Calcutta, 1842. 579-604. An immense number of references to writers who have touched on the medicinal properties of hemp, will be found in the elaborate essay entitled Studien über den Hanf, by Dr. G. Martius (Erlangen, 1855).

[2038] Personne, though he admits the activity of the resin prepared by Smith’s process, contends that it is a mixed body, and that further purification deprives it of all volatile matter and renders it inert. This is not astonishing when one finds that the “purification” was effected by treatment with caustic lime or soda-lime, and exposure to a temperature of 300° C. (572° F.)! That the resin of the Edinburgh chemists does not owe its activity to volatile matter, is proved by their own experiment of exposing a small quantity in a very thin layer to 82° C. for 8 hours: the medicinal action of the resin so treated was found to be unimpaired.
