    dedication and text of the Inquiry, and the four plates from the latter. The first of these, the cowpox on the hand of Sarah Nelmes, has been pronounced by many contemporaries an admirable representation; the next shows a vesicle, the second remove from a sore heel or grease case; the next the vesicle in a late stage on the arm of William Pead; and the last that on the arm of Hannah Excell, the last three being from the sec- ond experiments described in the Inquiry. I show also Jenner's set of pictures published in 1801, from drawings by William Cuff, who had colored Jenner's earlier plates and afterwards made some for other books. He stated before the parliamentary hearing that he had seen hundreds of vaccine vesicles, and the fidelity of his work has always been admitted. With this, a photograph of Jenner's Instructions will be in- teresting. Finally, by the kindness of Dr. J. H. Mc- Collom, of Boston, I show the plate of Bousquet, pub- lished in 1836 (J. B. Bousquet, Sur le Cowpox {Petite vcrole des Vaches) decouvert a Passy, etc., Paris. 1836.) showing the appearances of vaccine vesicles from a recent case of cowpox, and from the virus of 1800. The degeneration of the older virus is evident, yet I think few will affirm that it is not better than most of the material now available. Let me recall in a summary way what Jenner did with vaccination. He recognized, and made others ■ recognize, the protection given by cowpox against smallpox. The truth of this belief I do not consider it necessary to discuss. Any one willing to take the pains to make an extensive study of the matter, will, I think, draw no other conclusion.
