    October 26. — The original vesicles and papules have, in many of the clusters, resolved themselves apparently into two or three times their number of smaller efflorescences, the whole patch flattening down and assuming a darker brown tinge. October 27. — A large single vesicle, with the thick and opaque covering peculiar to its seat, has struggled up into distinct prominence in the palm of the right hand, near its ulnar border; a fresh one also at the base of the nail of the left thumb. At this date there are seven single or groups of efflo- rescences on different parts of the hands, in all stages of development or involution. November 1. — Another small vesicle has appeared in the right palm, half an inch from that of October 27. The earlier vesicles have nearly all flattened down to the level of the general surface. November 3. — A single vesicle shows itself upon the internal lateral surface of the left thumb. This was the last to appear, and from this date all the efflorescences gradually subsided, and after a fort- night were no longer perceptible. At the present time, November 26, their seats are still defined by the more glossy look of the new epidermis which covers them. This may be taken as a description of the effects of the poison upon the human skin in its mildest form. The changes, however, as described, are typical of the peculiar efflorescence in all cases. In what respects it falls short of the manifestations in its severest forms may be learned by comparison with the his- tories of the following cases.
