_Corium._—The vessels were dilated, with some cellular infiltration about them. The collagen appeared to be normal, with the exception of slight œdema, but the elastin was apparently reduced in quantity, especially in the papillary layer, and it was to some extent fragmented in places. It should be mentioned that the specimen was stretched on a small piece of cork in the process of hardening. The elastin stained, however, much as in the normal condition. Altogether there was little to be gathered from the histology _quâ_ cause, except that the appearances of the blood-vessels perhaps pointed to a general blood condition. Dr. Thiele, Pathologist to University College Hospital, kindly examined the blood and reported: Total red corpuscles per c.mm., 6,560,000; total whites per c.mm., 21,878. Hæmoglobin, 84%. C.T., 65. Differential count of whites: Small lymphocytes, 18·2%; large lymphocytes, 9·4%; neutrophiles, 60·7%; oxyphiles, 1·6%: hyaline cells, 2·1%. Footnote 1: _Amer. Journ. Cut.

PARKES WEBER, M.D., F.R.C.P., AND PAUL DASER, M.D. The patient, Jakob Z——, is a Polish Jew, aged 46 years, from Galicia, who has lived nine years in England, and says he has enjoyed good health. There is no evidence of previous alcoholism or syphilis. The patient was brought by Dr. Weber before the Dermatological Society of London on February 8th, 1905. The present illness commenced about three years before, when he chanced to wound the sole of his right foot with a nail. A pedunculated growth, about the size of a cherry, arose from the wound. This description reminds one of the strawberry-like granulation tumours sometimes growing from small wounds or ulcers on the fingers, which have been termed “botryomycosis,” or rather “botryomycomata,” because at one time they were supposed to be caused by the “botryomyces.”[2] The growth was removed by a doctor. Afterwards small bluish nodules developed from time to time on the feet and legs. Some of these nodules apparently undergo the following series of changes: They slowly increase in size, and after about three months constitute little pendulous tumours, which ultimately fall off spontaneously or else are knocked off or pulled off by chance; in this way local healing occurs, but fresh nodules form elsewhere. Though, as stated, some of the nodules become pedunculated growths, others appear to atrophy and merely leave brownish pigment in the skin, whilst others seem to undergo very little change, and, at all events, persist for a long time in their primitive form, namely, as hard bluish lumps under the epidermis. Treatment has been as yet without result.
