in the diagnosis. The bacteria usually held responsible 
for botryomycosis could not be isolated. Just what can 
be done for the condition is difficult to state, since seals 
are scarcely tractable animals. 
The following case has some features like paralytic 
hemoglobinuric fever and is reported as a matter of 
record. The long standing gastroenteritis may have been 
the basis for the intoxication which led to the paralysis 
and muscular degeneration. This laboratory has now 
under way studies upon the laming of ungulates, accom- 
panied by weakness of the hind-quarters, but no con- 
clusions have been reached. It is interesting to note that 
Hutyra and Marek quote Johne as having seen a case of 
hemoglobinuric paralysis in a zebra in 1879. 
Burchell's Zebra {Equus burchelli burchelli). The only symptom 
observed in this animal was gradually increasing lassitude which was 
first noticed about three months ago; toward the end he habitually 
stood with tucked tail and nose to the ground as if asleep. He ate well 
and digestion appeared good, but he became very weak as shown by his 
inability to rise when he got down on the third and second day before 
he died, although on both occasions he was able to stand when lifted.
