entire course, and in one part it was plugged with a curd-like 
or cheesy substance. A similar substance, which had been 
removed on Feb. 15th, I enclose with the other morbid parts. 
The right kidney was one complete mass of disease, its struc¬ 
ture being softened and entirely broken up. The pelvic cavity 
contained a dark-coloured matter similar to that found in the 
bladder. 
The further description of the parts I will leave in your 
hands. The thickened substance formed a coating to the 
inside of the bladder, and escaped on its being opened. There 
was also one small calculus in addition to the one I forward 
found in the viscus. 
[The parts referred to in the foregoing case were forwarded 
to Prof. Tuson, who informs us that they were in such an 
advanced state of decomposition when received at the college, 
that no correct opinion could be formed of their pathological 
condition. Prof. Tuson thus describes the urethral calculus : 
It is irregularly ovoid in shape, being about one and a 
quarter inch long, by about three quarters of an inch wide; 
the surface is nodular and highly crystalline. Its colour is 
yellowish-brown, and its weight II6T2 grains. By chemical 
analysis and microscopic examination, it was ascertained that 
the calculus consisted of carbonate of calcium with small 
quantities of carbodate of magnesium and organic matter, 
chiefly mucus.^’— Eds.] 
BEMABIvABLE CASE OF PENETRATION OF THE 
THORAX OF A COW WITH A STAKE. 
By R. Metherell & Son, Veterinary Surgeons, Spalding. 
Some few days before Christmas last we were sent for by 
Mr. Dennison, of Moulton Chapel, to see a cow with a 
wound on the inner side of her off fore-leg, she having been 
gored, as was supposed, by another, a vicious cow, which was 
kept in the same crew-yard. On examining the animal, a 
deep wound was found which readily admitted a probe to be 
passed fully six inches up it. Considerable swelling was 
present, and also some emphysema. On further examination, 
a hard substance was detected on the infero-lateral part of the 
sternum, posterior to the right limb, which on being cut down 
upon proved to be a large stake. As the stake could not be 
readily withdrawn from the original wound in consequence of 
its broken end being so far removed from the opening, and the
