SOCIETY MEETINGS. 
Quoting from Quill’s translation, I notice that of 105 cases 
the maxillary bones were affected in 51 per cent., the tongue 29 
per cent., the larynx and trachea 6 per cent. In France' and 
Germany the maxillae bones were the most observed. In Italy 
all the clinical forms are met with. In the county of Norfolk, 
England, 8 per cent, of the cattle affected localizations were on 
the jaws and tongue (Cruikshank). In Russia the disease 
abounds in all centres and in certain regions. In this country 
actinomycosis abounds to a high degree. Hundreds of cattle are 
condemned yearly in the different markets ; 3 per cent, of 
the cattle shipped from Canada to England show the lesions, 
From the foregoing the question arises how are we to study 
the different anatomical alterations ? 
(1) I n Bovines. Actinomycosis of the jaws. The localiza¬ 
tions on the jaws correspond to tumors ; this is the most com¬ 
monly observed. The disease appears as an inflammatory swell¬ 
ing which first begins somewhere along the lower or upper jaw 
or on the side of the face. It is often accompanied by a sensi¬ 
bility of the region and difficulty in mastication. " It grows 
slowly and takes quite a long time before it reaches any size. 
Abscesses which open to the exterior emit a creamy, thick, 
doughy-like pus mixed with small yellowish grains. Put a 
probe into the orifice and we will discern a regular fistulous 
tract, separated by soft tissues. One peculiar aspect of this 
disease is the fact that the pus has no odor and will come away 
in strings. The teeth become loose, mastication is slow and 
one-sided; these fistulous openings are surrounded by black 
granulations, sometimes attaining the size of a cocoannt; the 
animal becomes emaciated ; grave functional troubles arise, and 
unless killed, will succumb. 
(2) Actinomycosis of the tongue. First symptoms consist 
of the difficulty of the animal in prehension, mastication is slow 
and incomplete, the tongue cannot be extended from the mouth, 
it is tumefied and painful, and an abundant salivation. At this 
stage we find the tongue hard, rigid and voluminous (here we 
get the name “ woody tongue ”), and showing all over little 
knots of a yellowish color from the size of a pea to a goose egg, 
embedded in the mucous membrane. Here we observe the ap¬ 
petite is failing, the animal becomes emaciated, the disease is 
rapid and at the expiration of a few weeks the animal suc¬ 
cumbs to inanition, if not sacrificed. 
(3) Actinomycosis of the pharynx. The disease in this 
region is discovered by direct exploration of the mouth. These
