tongue, heart, liver, kidneys, etc., to the New Fork Post-Gra 
uate Medical College. In my last report to the New Jerst 
State Board of Health, I gave a brief acount of the disease, whic 
was published in the Agricultural Report. 
A carefully prepared paper on actinomycosis in men and an 
mals by Prof. Thomas E. Satterthwaite appeared in a recent nun 
her of the Quarterly Bulletin of the Clinical Society of the Ne 
Fork I ost-Graduate Medical School and Hospital. The artic] 
has special reference to the case in question and is as follows 
a Past winter I received a specimen of actinomycosis bovi 
from Dr. Lowe, Veterinarian and State Inspector in Patersor 
New Jersey. In this case the disease had attacked the upper jaw o 
a cow and the bones of the face were all more or less involved, th 
nasal roof being pressed outwards and the vault of the mout 
forced down by the new formation, which had finally perforate! 
the skin at the middle of the nose. In the puriform materia 
that exuded I detected the characteristic yellowish white or lemoi 
yellow granules that have been described in connection with thi 
disease. It is generally known that Bollinger, in 1877, first call 
ed attention to the parasitic nature of the affection. Previously 
it had been known, in Germany at least, by the name of U haut 
zotz, osteosarcoma, etc., but its real nature has not been appre 
ciated. 
In attacking the jaws of cattle it usually arises from th< 
alveolar ridges, or from the cancellus tissue, and in the latter cast 
it may easily be mistaken for a central osteosarcoma. On sectioi 
'0 growth was permeated by bony traveculee, in whose interstices 
r ramifying passages, as they may be called, was a greenish yel 
low deposit, which proved on microscopic examination to be a low 
form of embryonic connective tissue, in which were embedded 
the actinomycistic bodies. These varied in size from a barleycorn 
upwards, were capsulated, yellow, and had a fatty feel. 
Similar deposits have been found by some observers in the 
pharynx, larynx, gastric and mucous membrance and contiguous 
lymphatic glands of cattle. Sometimes there were fluctuating 
tumors near the angle of jaw, but apparently unconnected with it. 
Occasionally these deposits simulated in gross appearance, tuber-
