    settles in the lungs, and it follows that when the pulmonary structure hreaks down it may be expelled with the sputum. Similar observations had already been made by Manson.89 A special interest attaches to the Distoma Westermanii or pul- monale.90 The worm is cylindrical, of a reddish-brown colour, with a prickly surface, 8-10 mm. long and 4-6 mm. broad. The genital pore is situated behind the ventral sucker. The intestinal processes are unbranched. The uterus is globular, and lies immediately behind the genital pore. The male organ is bipartite, and placed in the hinder part of the body. The parasite infests the lungs of cats and the pre- datory feline tribe, but is found also in those of men, and, in particular, amongst the Japanese. It is then a cause of haemoptysis, and the eggs are seen in the sputum. They are brown, 0.08-0.1 mm. long and 0.05 mm. broad, and have blunt ends.

Crystals.—Very many forms of crystals have been found in the sputum, but for the most part their discovery is without great significance in diagnosis. 1. Charcot-Leyden Crystals.—We shall consider these bodies first, for the reason that they seem to possess some pathological interest. Leyden91 often found crystals in the sputum of asthmatic patients. They abounded chiefly in the semi-solid greyish-yellow pellets discharged during a paroxysm. The crystals were colourless and of the pointed octahedral form. They were insoluble in cold water, sether, alcohol, and chloroform, but dissolved readily in acetic and mineral acids, alkalies, warm water, and ammonia. They are identical with the crystals to be seen in post-mortem blood, and described at p. 120, and with those of the semen, and with others that are met with in the faeces in cases of anchylostomiasis. Sclireiner92 believes that such crystals are the phosphate of a new base, which, according to the researches of
