'Third._Cut through sternum and linea alba, also abdomi¬

porirth.—Examine peritoneum, omentum, small intestines

pifth._Remove liver and hepatic glands, examine uterus 
and kidneys. 
3ixth.—Cut diaphragm and remove thoracic portion of 
trachea, lungs, and heart 5 and examine lungs, bronchial, and 
mediastinal glands. 
Seventh.—Lastly examine prescapulai and retro-pharyngeal

It would require too much time to describe the pathological 
appearances ; furthermore we are all more or less familiar with 
the descriptions. I will, however, speak of one form of the dis¬ 
ease which may cause some one trouble ; that is what is known 
as infiltration of tubercle. In this case the characteristic nodule 
or tubercle is not found ; but there is a diffuse inflammation 
through the organ affected, giving it an indurated feel. Upon 
microscopical examination numerous collections of cells may 
be seen, something similar to the beginning of a tubercle. 
As bovine tuberculosis is of the most importance to the vet¬ 
erinarian, I will only briefly speak of it in other animals. Of 
the common domesticated animals, the hog is perhaps the most 
subject to the disease after the ox. Quite often they are affected 
when the cattle are badly diseased. Tuberculosis runs a much 
quicker course in hogs and port-mortems show more of the soften¬ 
ing and very little of the calcareous stage. Horses are occasionally 
affected ; when seen it is usually more advanced in the intes¬ 
tines than lungs. Hens and dogs running in the barn with a 
badly infected herd, sometimes contract the disease. Tubercu¬ 
losis is very destructive to menageries of caged wild animals. 
In closing let us remember that the time is soon coming 
when there will be a more rigid examination of neat and beef 
cattle here in America ; it therefore behooves us as young vet¬ 
erinarians to become thoroughly acquainted with tuberculosis.
