    The green colour seems undoubtedly due to the presence of biliverdin, which is probably formed in the stomach by the action of the acid solution of hydrochlorate of bme on the bili- phsein. Hence the occurrence of green vomiting need not be regarded as indicative of any peculiar morbid change. A brief notice of a green fluid vomited during an attack of sporadic cholera^ may be found in vol. 1, p. 18, of Heller’s Archiv.] Vomitus with urinary constituents. It is stated that in those cases in which the formation and excretion of the mine are impeded its constituents are discharged Avith vomited matters. Nysten^ and Bai’ruel had an opportunity of analysing a vomited fluid which contained urea, uric acid, and the ordinary urinary salts. [Dr. Halbday Douglas has reported a case in which urea was detected in the vomited fluid. London and Edinburgh Monthly Journal of Medical Science, vol. 1, p. 410.] Vomitus in carcinoma. In carcinoma of the stomach a fluid is vomited which de- posits masses of chocolate or cofiee-coloured flocks on the bottom of the vessel, while others are observed on the surface of the fluid. On examining a few of them under the microscope we observe a considerable quantity of large rounded cells with yellow gramdar contents, and also a very great number of fat-vesicles, some larger and others smaller than the cells. Remnants of food, and especially undigested starch-grantdes, are likewise frequently observed. The latter may be easily mistaken for fat-vesicles, but moderately strong compression causes their envelopes to break, and on the addition of a solution of iodine they assume a blue colour. By this test aU ambiguity is avoided. [Dr. George Wdson has published a notice of the chemical and microscopical characters of the fluid ejected in pyrosis— ' Joiu'n. de Chem. Med. 1820, Ser. Ill, p. 257.
