There being 110 business, the association proceeded to the 
consideration of papers. 
.Dr. J. B. Wright presented the first paper, on “ Actinomy¬ 
cosis, ” as follows : 
actinomycosis 
is an infectious disease and due to the entrance into the tis¬ 
sues of a vegetable parasite named the actinomyces. It is char¬ 
acterized by the presence of suppuration and inflammatory new 
formations in various tissues. It lias.been seen in the pig, ox, 
horse, sheep, and also in man, but it attacks bovines by prefer¬

the name of osteosarcoma or tumors of the jaws, due, as was 
supposed, to the action of various kinds, such as a kick or prod 
with the horn. Some authors described this disease as of a 
cancerous or tuberculous nature. Eater these facts were dis¬ 
pelled by Perriconti and Revolta when they"discovered in these 
tumors the presence of a parasite divided into short filaments 
and club-like in shape. About two years later Bollinger began 
his first researches on these tumors on the jaws of the ox, and 
demonstrated a cauliflower - like parasite, which the botanist, 
Hartz, after a great deal of study, named the actinomyces. 
Since then we have the name actinomycosis. Since that time 
numerous observations have been made and we find "Nocard 
recognizes this disease for the first time in 1884. We are told 
that the same alterations are met with in other tissues of the 
body. Since Nocard’s investigations numerous observations 
have been made in the study of actinomyces 011 the various 
animals affected. Actinomyces belong to the vegetable king-
