CORRESPONDENCE. 
which I wish to solve is, How did this congestion of the kidneys 
occur, so as to produce a kind of haemoglobimuria ? Is it probable 
that the inactivity of the bowels during the colic was the cause 
of the bloody urinating ? Or have I got to search the cause in a 
malassimilation of albumen, which by haemoglobimuria (according 
to the examinations by Prof. Siedamgrotzky) produces a poison, 
and the latter causes the congestions of the kidneys and spiual 
cord? The horse is a very fleshy, heavy, young Norman horse, 
and lias been fed very much upon corn. It is unfortunate that I 
could obtain no urine to make a microscopic examination. Hop¬ 
ing that you can give me some explanation of this case, I remain, 
Yours respectfully,

POLYPUS OF THE BLADDER. 
Fort Walla Walla, W. T., April 10, 1883. 
Editor Review : 
I send you to-day, by express, a tumor of unusual and peculiar 
growth, that I trust will be interesting in your museum, and 
otherwise useful. 
A condemned cavalry horse,.live or six years old, died on 
March 26th, a short time previous showing slight colicky symp¬ 
toms, with dripping of urine. On making a post-mortem exam¬ 
ination, I found the organs, with exception of kidneys and blad¬ 
der, in a healthy condition. The latter was very much enlarged 
and thickened, with appearance of chronic inflammation, and in 
a state of atony. On opening it, I found this peculiar polypus 
attached to the neck at the prostates. It is about 12 or 15 inches 
long, weighed 22 ounces, and is of a cauliflower growth. 
The kidneys were pale, soft and enlarged. 
It has been in absolute alcohol since March 26th, and, I trust, 
will reach you in a satisfactory state of preservation. 
Wishing anxiously to hear from you on the subject, 
I am, with much respect, 
H. B. Corcoran, Y.S., 1st U. S. C.

scopic examination.— Ed.]
