being usually employed, and for the second vesuvine, which gives 
the background. The blood collected in the sealed glass tubes 
was treated and prepared for examination in a similar manner. 
Examining the blood in such preparations, I observed that the 
white blood corpuscles were, as a rule, more numerous than nor 
mal, and as a constant appearance in the blood of this disease 
was the presence of a micrococds, this bacterium was found in 
large numbers, either singly or in pairs, or in torular chains, and 
most frequently in zooglia masses, this appearance being repre¬ 
sented in the accompanying drawing, and from an original prep- 
eration, and reproduced directly from the microscope, by the aid 
of the camera lucida. This sphero bacterium is of pale white or 
yellowish color, and in micrometic measurements, is shown to be 
on the average one fifteen-thousandths of an inch in diameter. 
This organism I never failed to find in any of the cases observed 
by me, either during life or after the death of the animal.

INFLAMMATION. 
By E. Mink, V.S. 
There is perhaps no topic in pathology that has been so 
thoroughly investigated as the morbid process known by the term 
inflammation ; yet at the present time it is difficult to give a short 
and adequate definition of this term. Nearly all, however, who 
are now regarded as authority on this subject agree substantially 
upon its processes, products, variations and terminations. 
The morbid process known by the term inflammation consists 
of a succession of. changes in the living tissue of the parts affect¬ 
ed, and take place in nearly the following order : 
First, changes in the blood vessels and circulation ; second, 
exudation of liquor sanguinis, and migration of blood corpuscles; 
and third, alteration in the nutrition of the inflamed parts. 
Recklinghausen, in 1863, discovered the existence of wander¬ 
ing cells in the tissues. This discovery raised a doubt of the 
correctness of the theories of inflammation advocated by Vir-
