This condition, as described by our author, is never found in the 
regularly worked and properly fed horse. But always is found, when 
found at all, after a period of several days’ confinement to the barn ; 
and then only when the animal is fed the full quantity or more of food 
that he should have when at work, and possibly food of the richest 
character in all the elements that go to build up the horse. The conse¬ 
quence is the blood becomes surcharged with carbon, fibrin, and other 
elements eliminated from the redundancy of rich food which renders it 
unfit for circulation. The nervous system suffers in proportion to this 
blood derangement, and under these circumstances, the animal is put to 
work. His spirits rise in anticipation of escaping confinement; the cir¬ 
culation of the blood becomes more active; the actions of the various 
organs of the body, particularly the kidneys, increase. He is harnessed 
and starts, but does not get ten rods from the barn, perhaps, before he 
comes to a stop, or gives such evidence of being unwell that the veriest 
dolt could see it. The driver perhaps thinks he has got the “ belly¬ 
ache.” He reasons thus, the horse has been idle some days and has 
filled himself too full, a sharp drive will do him good. The whip is 
applied ; he is forced to go a longer or shorter distance. And likely 
this occurs miles away from an intelligent Veterinarian. Thus several 
hours elapse before assistance worth having arrives. The period is past 
when remedial measures can be of any use, and death closes the scene. 
I think that “ engorgement ” of the kidneys would be a better name for 
the diseased condition described by our author than hoemoglobinuria.

Editor of A. V. Review : 
Dear Sir :—The following case, being of somewhat rare occur¬ 
rence, it may possibly be worth recording in the Review. 
About a month ago, I was consulted by Mr. A. Van Inwagen, of 
this city, respecting a four-year old colt (which had recently come into 
his possession), and which had a fistula at the base of the right ear, 
which had existed for over three years, and had been under treatment 
by an empiric for the last six months without effect. 
On passing a probe up the sinus, which was straight, I detected 
that at the bottom was an apparently bony substance, which I at first
