This then is a working classification of the hepatic cirrhoses. Perhaps many slightly differing varieties might be constructed but this grouping will permit comparison and contrast with human cases, and with instances in the various orders. Because of the relatively small total, thirty- two, it is perhaps unwise to attempt any conclusions as to distribution but it is certainly noteworthy that twenty-six occurred in mammals. This means 1.6 per cent. in mammalian autopsies against .2 per cent. in avian. Among the former class the carnivores stand at the head of the list, followed in order by the marsupials, ungulates, primates, and rodents. Carnivora have shown a few typical portal cirrhoses from a pathological standpoint but only one, in a badger (_Taxidea taxus_), was combined with the classical picture of intestinal hyperemia and ascites. Two of the cases were combined with chronic enteritis which may, of course, have been secondary but there was also a hyperplasia of the spleen which bespoke some grade of infection. None of the four showed involvement of the biliary tract. One animal, a skunk (_Mephitis mesomelas_), was jaundiced; it had anemia, nephritis and enlarged spleen but no intestinal inflammation; perhaps the associated anemia may have been responsible for the pigmentation. Biliary cirrhosis occurred in two Carnivora, in both associated with enlarged spleen and nephritis. One showed jaundice and the other, with a huge liver from congestion and interstitial infiltration, had a small ascites. Fatty cirrhosis was diagnosed in a raccoon but this is viewed with some reservation because this animal easily stores fat and in this case it may not have been a part of the process. In none of the foregoing cases did parasitism enter into the causation of the change and I shall always specify when such a factor was probable. The only vascular cirrhosis in our records occurred in a Gray Wolf incident to a longstanding myocarditis (Gray Wolf, _Canis lupus mexicanus_, Myocarditis, Adenomatoid goitre, Chronic gastroenteritis, Vascular cirrhosis of liver, Subacute diffuse nephritis, Edema of lungs, pericardium, and peritoneum). Two examples of perilobular fibrosis appeared in this order, a raccoon (_Procyon lotor_) and a paradoxure (_Trichosurus vulpecular vulpecular_). The only noteworthy feature was, in the former, a very marked biliary stasis on the lobular margins and in the connective tissue; this animal was not jaundiced.
