pearances of actinomycosis, always requires a strict examination 
of the animal in this direction. As soon as a second affected spot 
is detected, or the local affection exists in a more aggravated 
stage, accompanied by putrid decay, etc., we must not hesitate to 
consider the meat affected and condemn it. As long, however, 
as the disease appears only locally, existing in a slight degree, 
and the tissues of the swellings are solid, this measure does not 
seem to be necessary, according to the present knowledge of 
actinomycosis. 
Of the 143 trichinous swine, 132 were of native breeds, 3 of 
Russian, 4 of Servian, and 1 of Saxon; 53 times the trichinae 
were very numerous, 111 they were capsulated and all alive, 17 
times dead and living trichinae were present at the same time, 
and 15 times lifeless ones only could be detected. Repeatedly it 
happened that several swine (5 to 6) which were sold by one and 
the same dealer were trichinous. Suspecting that these animals 
came from one farm, requisite researches with the aid of the 
police authorities were instituted, but in a single instance only 
was the supposition verified. In other instances the researches 
proved unsuccessful, because shortly before the sale the swine, in 
company with others, were found in different hands and their 
identity too difficult to establish. 
As soon as trichinae in the same earlier stage of development 
are detected in a number of swine out of one farm, it may be as¬ 
sumed that the source of contagion is to be found on the farm in 
question, and that other swine kept there are also trichinous. To 
make these suppositions sure by investigations is of great im¬ 
portance to the public welfare, because thereby it is possible to 
remove herds affected with trichinae and to keep the suspicious 
swine under surveillance until they are slaughtered and examined.
