Quail Epidemic of January and February, 1915. 
Last year's report contained a detailed account of 
an epidemic of ''quail disease" imported to the garden 
and destroying all but two of forty-eight new birds. 
There was isolated from these birds an organism corre- 
sponding to the Bac. scoticus (Migula) believed to be 
the cause of the disease, according to the observations of 
Morse. We obtained from Dr. Kalbfus of the Pennsyl- 
vania State Game Commission, four perfectly healthy 
birds for experimentation. A culture of the isolated germ 
was injected into two of them and mixed with the food of 
the remaining two. It does not seem profitable to cite 
the details of the work as the results were entirely nega- 
tive, no lesions resulting that bore the slightest resem- 
blance to the spontaneous disease. The birds either lived 
indefinitely or succumbed to wholly foreign conditions. 
This negative experiment is of course no proof that the 
organism is not the cause of quail disease, for the methods 
employed might not be the correct ones to propagate the 
virus or the germ may have lost its virulence during the 
laboratory cultural w^ork. However, as some observers 
have not reported this bacillus in the disease this germ 
loses something in importance by the negative inocula- 
tion experiment. 
Cretin Wolves. 
A healthy Gray Wolf gave birth on March 28, 1915, 
to seven pups, two of which died from weakness very 
shortly and were not brought to the laboratory. The 
remaining five died from 2 months to 7 months later. 
They are interesting in the fact that they were all 
cretins, and presented various thyroid alterations. In
