The production was marked throughout great quaintness of style, and excited a languid interest. Some very good drawings illustrative of disease of stomach were exhibited. Amongst others we noticed sphacelus of the stomach succeeding carcinoma, enlargement of mucous follicles, hemorrhage from the villous ooat, &c.
