worse. I of course varied the treatment as I thought the 
circumstances required, and persevered daily until the 24th 
of November, when I saw no hopes whatever of her recovery ; 
and the owner now coinciding with me, we had her killed. 
Examination after death . — The coffin-bone on the inside, 
where the nail had penetrated, was a little discoloured, and 
the navicular bone was found to have been fractured on the 
outside. The preparation of this is, through the kindness of 
the secretary, placed in the museum of the Royal College of 
Veterinary Surgeons. 
CASE OF URINARY DEPOSIT. 
By Gr. Evans, M.R.C.V.S., Bridgenorth. 
Dear Sir, — I thank you for microscopically examining 
the sediment of the urine I sent to you. I send you the 
following account of the case in which it occurred, because 
you have wished me to do so ; at least, it appears to me that 
I am one of those alluded to on the cover of your last num- 
ber, who have sent to you somewhat incomplete cases. 
On July 13th, I saw the horse for the first time. He was 
then so weak that he could hardly stand ; laid down a good 
deal, and was as thin as any gipsy horse I ever saw in my 
life ; rough coat ; anxious expression of the countenance ; 
he often looked at his sides, and the owner complained that 
“ he staled very badly, voided little at a time ; not very often, 
and there was no pain in the act of doing it.” As he did 
not attempt to stale while I was there, I passed the catheter 
into his bladder, and withdrew about a pint of urine, of a 
yellowish straw-colour, slimy, which deposited some lime 
salts, which you say “ chiefly consisted of carbonate of lime, 
crystallized in somewhat an unusual form, and some of the 
phosphates were also present.” As to the quantity then, it was 
nothing compared to what we often see in apparently healthy 
urine. The bladder, ureters, and urethra, were, as far as I 
could make out, all right. There was slight flinching upon 
pressure being applied over the region of the kidneys, and I 
fancied more on the right side than on the left ; but I did not 
put too much dependence upon that as 1 have seen it in some 
healthy animals. It only served to create suspicion. 
History . — The animal is a five-year-old cart-horse, a violent 
worker upon a hilly farm and bad roads. He is always put
