have to be put into a separate cage until proved infected. 
Scrupulous cleansing of the enclosure is desirable, but 
how efficacious is difficult to state. 
Porcupines. 
On April 16th, 1914, a lot of six Canada Porcupines 
{Erethizon dorsatus dorsatus) arrived; by May 2d all had 
died. The following are the various diagnoses, 3183 
acute follicular enteritis, hemorrhagic pancreatitis, acute 
splenitis, acute lymphadenities, cestodes in intestines, 
oxyuris in cecum, filaria in peritoneum; 3184, acute 
parenchymatous nephritis, cestodes in intestines; 3189, 
acute follicular entero-colitis, acute lymphadenitis, ces- 
todes in intestines, filaria in peritoneum, oxyuris in cecum, 
filaria embryos in blood; 3190, cestodes in intestine, 
ffiaria in peritoneum, oxyuris in cecum, decomposition; 
3193, obstructed labor, hydroperitoneum, peritoneal and 
subcutaneous filaria, ffiaria embryos in blood; 3194, 
acute serous peritonitis, acute parenchymatous nephritis 
hemorrhage in kidney containing ffiaria embryos, 
cloudy swelling of heart muscle, dilitation of heart, con- 
gestion of liver, ffiaria embryos in liver, acute suppura- 
tive catarrhal endometritis, hemorrhage in myometrium, 
chorionepithelioma, ffiaria in blood, peritoneal and sub- 
cutaneous ffiaria, foreign bodies (quills) in peritoneal 
muscles. These animals were all heavily infested with 
worms, especially ffiaria, which were found as adults 
chiefly in the peritoneum, and as embryos in the blood 
and in blood collections. There does not appear to be 
any one cause for the deaths aside from the parasties 
to which I am inclined to attribute but a secondary or 
predisposing role. Three of the beasts suffered with an 
acute general infection (3183, 3189, 3194); the worms 
may have acted as a depressant of natural resistance to 
some bacterial infection. The worms probably had 
nothing to do with the dystocia in 3193. There is no 
indication that the parasitic infestation has produced 
any severe grade of anemia. The most probable reason 
for the loss of these animals seems to be that they were 
unable to adjust themselves to the new conditions in 
the Garden because of the presence of two varieties of 
worms in considerable numbers.
