    2 place. At first the spirit contained a very large amount of leucin and tyrosin, some of wliich are still present in the specimen exhibited. The somewhat sigmoid, spindle-shaped crystals which are exhibited have all the characters of Charcot's crystals. They are fragile, soluble in boiling water, practically insoluble in cold water, soluble in most organic and inorganic acids and bases. Insoluble in alcohol, ether, chloroform, and turpentine. They are supposed to be phosphates of a basis discovered by Schreiner and called spermine. This spermine is supposed now to be the active principle of Brown-Sequard's fluid (testicular extract). January 20i7i, 1891. Charcofs crystals in fcsces. {Card specimen.) By Sheridan Delepine, M.B., B.Sc. THIS alvine discharge came from a female child, twelve years of age, about whom Dr. Lauder Brunton was consulted during the month of June, 1890. The child had had measles, and soon after convalescence is supposed to have caught cold. She was taken with diarrhoea and much pain in the abdomen. The evacua- tion soon became dysenteric in character. No physical sign could be detected. I am indebted to Dr. Brunton for two specimens of the faeces obtained on the 20th, and the other on the 27th of June. These two specimens were similar in characters. Description of the fseces.—Very thin, watery, brownish, greenish yellow, semi-translucent. Sediment composed of an upper layer of greyish, yellowish white opaque mattei', and of a thinner lower layer, composed of reddish orange, coarse granules resembling cayenne pepper. The smell of the fluid was peculiarly sour and unpleasant. The filtered fluid was alkaline, gave clearly an albuminous precipitate, but no bile-pigment reaction. The reddish masses at the bottom, when treated with nitric acid, gave the usual play of colours indicating the presence of bile-pigment, and
