FIBRO-VASCULAR TUMOUR IN THE BLADDER. 383 
ascertain the true character of the urine when called upon to 
treat similar cases. Such a procedure will materially aid 
him, not only in forming a correct diagnosis and prognosis, but 
also to speak with some degree of confidence should he be 
called into the witness-box to give evidence, or have to take 
part in arbitrations on such matters. The province of the 
veterinary surgeon is wider than many suppose it to be, and 
it might be, with great advantage to the public, much more 
extended. 
I will now describe the morbid changes that had taken 
place in the organs sent by Mr. Kettle, which consisted 
of the bladder with the urethra, the ureters, kidneys, and 
a portion of the vagina, together with a large mass of ab¬ 
normal deposit situated between the upper surface of the 
urethra and neck of the bladder, and the under surface of a 
portion of the vagina, and more or less encircling the whole 
of these parts. This adventitious growth, which was a little 
flattened on its upper and under surfaces, formed a tumour 
of the size of a small child’s head. The bladder was greatly 
increased in size, its coats w 7 ere thickened, and like the 
tumour it was of a dirty purple colour, which probably de¬ 
pended upon the tissue being stained by effused blood. On 
laying the bladder open from one end to the other, exit was 
given to a large quantity of thick blood-coloured urine and 
clots of coagulated blood. This fluid was carefully examined, 
as was also the surface of the much thickened mucous mem¬ 
brane, with a view to ascertain if any calcareous deposit 
existed, but I could not discover a trace of any. The 
mucous membrane itself was of a dark colour, approaching 
to black, especially towards the neck of the organ, into 
which the tumour projected for a considerable distance. 
Here the surface of the tumour was uneven, the blood¬ 
vessels were enlarged, and many of them had given way, 
thus allowing the blood to escape into the bladder. 
A section was next made through the tumour, in a line 
with the urethral canal, so as to expose the whole of its 
structure. The centre of the mass was composed of dense 
fibrous tissue; the outer part was less dense, and seemed to 
be made up partly of the same material, but to a larger ex¬ 
tent of blood-vessels, fibrelized lymph, and coagulated blood. 
The central part was likewise of a dirty white colour, 
gradually approaching to a darker hue towards the outer 
surface, particularly at that part which was wdthin the 
bladder itself. I examined different parts of the diseased 
mass with the microscope, but was unable to discover that it 
was composed of anything more than a simple fibro-vascular
