tomy and physiology of the abscess and its contents, and the fol¬ 
lowing division is accordingly proposed: 
First.—The simple abscess , developed under the unique influ¬ 
ence of normal pyogenic microbes, containing no others, and ex¬ 
clusive of all others. 
Second.—The infected abscess, due to the influence of either 
normal pyogenic microbes, or of pyocolous microbes, evidentally 
pyogenic, but characterized by the presence of this last with all 
the consequences of this microbian justaposition. 
This division has a certain parallelism with the old method of 
idiopathic and symptomatic abscesses, but is preferable because 
it is better defined, and rests upon the precise presence of the 
elements which give to the pus its various characters.— Journ.

On March 3rd I was called to see a bay gelding, five years

the horse down, laying perfectly quiet, being unable to rise, the

driven had shied at something, got the best of the driver, and run 
into an iron fence, which was badly broken; the bay dropping 
down with apparently only a slight flesh wound of the thigh, 
made by a portion of the broken iron rail. I made an examina¬ 
tion of the back for injury to the spine, but could find no indica¬ 
tion of any; not being able to find a specific cause for the loss 
of power behind. I declined to order the destruction of the 
animal, stating that it was possible that it was due to nervous 
shock. The owner’s stable being near, I had him removed in the 
ambulance and placed in a well littered box stall, made a more 
careful examination and could find no visible injury, except the
