The echino- coccus is very rarely found in the human subject. Zeder discovered some in the brain of a young woman, occupying the third and fourth ventricles: they were about twelve in number, pyriform, and quite small. Muller has recently described an instance in which they were voided with the urine, by a man laboring under renal disease. But the most extraordinary case, perhaps, on record, is that published by Rendtorf. The sac containing the hyda- '" tids was developed in the brain: it was of large size, and weighed upwards of two pounds. The walls of the right ven- tricle, in which it was situated, were so at- tenuated as to be scarcely a line and a half in thickness. It should not be forgotten, that the name by which this genus is designated has reference to the rounded form of the body, and to the little asperities which cover it. The fifth genus, the acephalocystis, (Fig. 6,) by far the most interesting and common of all, was Fio. 6 founded by the celebrated Laennec, who published a very accurate account of it, in 1804, in his excellent " Memoir on Vesicular ; Occurring both in the human subject and in many of the inferior animals, the individuals of this class of parasites infest some organs much more frequently than others. They seem to have a remarkable predilection for the liver, owing, probably, to some peculiarity of struc- ture favoring their developement. The brain, ovary, uterus, mammary gland, spleen, and kidney, are also sometimes their.
