BLADDER OF A HORSE CONTAINING CALCAREOUS DEPOSIT. 193 
tongue was coated with a dark yellowish-brown fur, and its 
sides and edges were of a blueish-red tint. 
Such were the morbid appearances of the diseased parts, 
and which we think will be admitted are characteristic of death 
having been caused by the system becoming imbued with 
a septic poison that emanated from something undergoing 
decomposition either in the yard or near to it. 
These remarks, we hope, will elicit the opinions of members 
of the profession as to the real cause which gave rise to this 
disease in the above cases; and also excite a desire to ascer¬ 
tain w’hat plants are true poisons to our domestic animals. 
THE BLADDER OF A HORSE CONTAINING A 
LARGE QUANTITY OF CALCAREOUS DEPOSIT. 
By J. Grover, M.R.C.V.S., Lewes. 
Dear Sir, —I have forwarded you the bladder of a horse, 
containing much sabulous matter, just as it was taken 
from the animal. He had never been really ill from it, and 
was killed on account of his age, having worked up to the 
time he v T as destroyed. For the last year or two there 
has been a constant dripping of urine from the penis. 
I hope to see your remarks on it in the next number of 
the Veterinarian . 
I remain, dear Sir, 
Yours truly.

OBSERVATIONS BY MR. VARNELL. 
“ It will be seen by Mr. Grover’s letter that there were 
indications of derangement existing in the urinary appa¬ 
ratus of the horse for a year or two before he was destroyed, 
from his frequently passing only small quantities of urine at 
a time ; and, although it w as not observed, it is most pro¬ 
bable that it w ? as mixed with sabulous matter. 
“ I should have thought, from the weight and magnitude of 
the bladder and its contents, that there would have been 
a straddling gait, and perhaps some tumefaction of the hind 
extremities from the pressure imparted to the iliac veins. 
These symptoms, however, are so very common in old
