“Has performed experiments on living animals, and sometimes exhibited them (389-91), and considers such experiments absolutely necessary for the progress of physiology (393), and that scientific investigation by competent persons is important for the development of medical and surgical improvement (398-401).”--_Digest. Ev. Roy. Com._, p. 4. “The chief use of employing curari is to render the animal quite still; that is the great purpose of it. What Mr. Hutton says is quite true, that it is not generally recognised as an anæsthetic, and, therefore, not used as an anæsthetic.--Then it is a contrivance to save to the operator the trouble which the manifestation of pain by the animal might occasion him? It facilitates the operation at any rate.”--_Evid. Roy. Com._, Q. 462-3. =Sibson, Francis=, 59, Brook Street, W. M.D. Lond. 1848; M.D. Dub. (Hon.) 1867; F.R.C.P. Lond., 1853; Hon. D.C.L.
