SOCIETY MEETINGS. 
which embraced the examination under the microscope by the 
members present of specimens of trichinae which Dr. Stewart 
had furnished; it was deemed advisable to defer this until after 
the reading and discussion of Dr. Peters’ paper upon “ Meat 
Inspection.” (To be continued.') 
MASSACHUSETTS VETERINARY ASSOCIATION. 
The regular monthly meeting was held on the evening of 
Dec. 27th, at No. 19 Boylston Place, Boston. President Eang- 
don Frothingham called the meeting to order at 8.15. Minutes 
of previous meeting read and adopted. 
Dr. John M. Parker moved that the Secretary be instructed 
to send a constitution and application blank to every graduated 
practicing veterinarian in the State. Dr. Daniel Emerson 
seconded the motion. Carried. 
The essayist for the evening, Dr. Frothingham, read the 
following paper on “Actinomycosis.” 
He reviewed the subject of actinomycosis and compared this 
disease with botryomycosis, a disease of the horse manifested 
by an infectious tumor (botryomycoma), which both macroscop- 
ically and microscopically closely resembles the actinomycoma. 
Dr. F. spoke of the various animals in which actinomycosis has 
been observed, and the portions of the body where these tumors 
have been found. He spoke particularly of actinomycosis of 
the udder in cattle. Although the disease in this organ is 
rather uncommon, it has been thoroughly described by several 
European investigators. Jensen, of Copenhagen, for instance, 
has written of 20 cases and called attention to its occurrence in 
two distinct forms ; in one form, the more common, the lesions are 
usually not numerous, but are apt to be extensive, a single 
tumor becoming as large as a hen’s egg or even larger, and con¬ 
taining much pus. One or more quarters of the udder may be 
involved. 
In the other form the udder may become double its normal 
size in the course of a few months and is very hard and rough. 
Sometimes only one quarter, and sometimes all four are at¬ 
tacked. The cut surface may seem almost normal, but upon 
close inspection, the lobules are seen to be larger than usual and 
to contain nodules with purulent centres. These nodules may 
be exceedingly small, hardly visible to the unaided eye, or they 
may be as large as a pea. They may be found in countless 
numbers scattered throughout the gland and are also found on 
the mucous membrane of the milk ducts and cisterna. Such
