The liver-fluke^ the distoma hcpaticum, (Fig. minthologists, although said to have been several times found in the human subject, is much more common in the inferior animals, as the sheep, horse, stag, and ox. It is also found in the gall- bladder ; and Pallas mentions that he once de- tected it in the hepatic duct of a young female. Somewhat lanceolated in shape, it is of a yellow- ish color, obtuse at either extremity, and scarcely a fourth of an inch long, by one line in breadth. It has two openings, one in front, which is directed obliquely inwards, and another behind and inferiorly, which is slightly prominent, and answers to the anus ; the neck is rounded, and of a light brownish hue ; and the belly is marked by spots of an opaque dingy white. The insect is thought to have a distinct genital apparatus, with a vascular, and probably also a nervous system. In animals, it is often an inch long, by nearly half an inch broad. Worms sometimes crawl from the duodenum into the liver, where they have been known to create profuse suppuration, followed by fatal irritation. Of this I have never seen an example in the human subject, but several highly interesting cases of it are recorded by writers. The late Dr. Thomas Bond, of Philadelphia, has detailed the particulars of an ex- traordinary instance of hepatic disease occasioned by a worm nearly two feet long by one inch in diameter. On dissection, a large abscess was discovered in the substance of the liver, containing nearly two quarts of bloody Many other cases of a similar kind are related by authors; and it is worthy of remark that in nearly all of which I have read an account, the parasites belonged to the lumbricoid species. In the liver of the hog I have frequently seen the vessels and excretory ducts of the liver filled with small worms of this kind. In this animal they generally coexist with hydatids. In examin
