TUMOUR WITHIN THE VAGINA OF A COW. 
97 
cow on January 14th. The animal was in good condition, 
and was sent for slaughter to the Metropolitan Cattle Market. 
On the abdomen being opened, one ovarium was found to be 
enormously distended, round in form, and to weigh sixteen 
pounds. As soon as the tumour was cut into it collapsed, in 
consequence of the escape of the contained fluid—serum mixed 
with the blood. 
The sac was composed chiefly of the peritoneum, with a 
small portion of the fibrous stroma of tlie ovary, nowhere 
exceeding a quarter of an inch in thickness. 
The interior of the sac was pulpy in appearance, and 
covered with numerous small tufts of a yellow colour. 
These under the microscope were found to consist of fine 
white fibrous tissue, with many nuclei and cells, undergoing 
conversion into fibres, showing all the intermediate forms of 
oval, fusiform, and spindle-shaped cells. The uterus con¬ 
tained a foetus, and it did not appear that the presence of the 
ovarian tumour had materially interfered with the animal’s 
health. 
TUMOUR WITHIN THE VAGINA OF A COW. 
Mr. D.B. Howell, M.R.C.V.S., Reading, has forwarded 
to us an interesting specimen of a tumour which had formed 
beneath the mucous membrane of the vagina of a pregnant cow. 
It appears that the cow—an aged animal—had been consigned 
to a salesman at Reading; and that, on the day following her 
arrival, she gave indications of approaching parturition. No 
advance of the foetus taking place, an examination 
vaginam was in due time made by the consignee, who finding 
something’'’ to be occupying the passage which prevented 
the birth of the calf, [sent for Mr. Howell. Exploration at 
once revealed the existence of an immense tumour filling 
up the vaginal passage, and firmly pressing against the cervix 
uteri. With much difficulty the mouth of the womb was 
reached, when it was found that although the foetal presen¬ 
tation was natural, delivery was impossible. The animal was 
consequently slaughtered. 
The tumour, which is ovoid in form, with slightly flattened 
sides, measures in its long diameter fifteen inches, and in its 
short ten inches, having a circumference of twenty-five inches 
at its largest part. Its surface is smooth and unbroken, and 
covered with the mucous membrane. Its colour varies slightly 
in places, but as a whole it differs but little from the normal 
hue of the vagina. Its attachment, which is just above the
