THE COMMUNICABLE DISEASES 501 
tendency to calcification, both in the intra- and extra- 
pulmonary nodes. It is to be emphasized that in our 
material the thoracic lymph nodes are affected more 
than the abdominal and regional as 3 to 1. The apparent 
immunity of the spleen of this order is well illustrated. 
The paucity of serous surface involvements in the 
wild Bovidae and their prominence in the Cervidae cannot 
be ignored in the figures, but it seems misleading since 
pleural growths and adhesions are quite common in the 
domestic Bovidae. The case in the Equidas was that of a 
Zebra with a large tuberculous abscess in the retro- 
peritoneal glands forming a tumor in the left renal region. 
It was quite well surrounded by fibrosis, and the infection 
had not extended ; it seemed quite recent. Analysis of the 
figures for the remaining three families of ungulates 
offers little for contrast and much for comparison ; it is 
the usual picture as seen in the domestic cow. Some 
special cases are worthy of review. 
An interesting specimen of softened glands chiefly on 
one side of the neck was found in a Fallow deer {Cervus 
dama). It resembled the juvenile human cases that 
require surgical attention. Although palpable lymph 
nodes can be found in practically all cases of generalized 
tuberculosis in the Ungulata, this is the only case in our 
records in which they have presented a large tumefaction 
and broken down. Pulmonary cavitation is recorded but 
thrice, one for each of the last three families. Fibro- 
caseous tuberculosis of the testes was discovered in a 
Nylghaie {Boselaphus tragocamelus), but there is no 
knowledge of mating or offspring. An ischiorectal 
abscess was found in an American Bison {Bison bison) 
showing nodular precaseous tubercles of the lung. The 
former was the cause of death. No tubercle bacilli could 
be found in the abscess contents, so that the tuberculous 
basis is inferred, not proven. Tuberculous salpingitis 
in a Nylghaie was discussed on page 306.
