DISEASKI) KIDNEYS IN A CO^V.

the ureter, just over the pelvis, so as to examine its interior. I in¬ 
troduced my finger into the various branches inside, and found the 
tubes much dilated in the different lobes. It also contained a con¬ 
siderable quantity of muco-purulent matter; but much of it had 
escaped, and also out of the ureter, from a cut that had been made 
in the latter by the butcher. The substance of the kidney felt a 
little flabby when the matter was out of it; but it was kept some¬ 
what distended by the thickening of the different tubes ramifying 
throughout it. The inner membrane was of a pale colour. 
Tlie Ureter .—Its length was twenty-six inches. The breadth 
of the ureter forming the pelvis was three inches and a half. At 
the distance between the second and third inch from the kidne}", 
the ureter became more narrow, and was not above an inch and a 
half wide, on laying it flat and pressing the sides together. It then 
tapered suddenly off, and was about two inches wide, and continued 
so for eight inches. It afterwards gradually narrowed again to an 
inch and a half, and continued so for nearly the remainder of the 
length; but the last inch prior to entering into the bladder was about 
an inch wide. The united thickness of its coats was a quarter of 
an inch, but the central coat seemed the principal one, and the in¬ 
ner one was so closely attached as to be scarcely distinguishable 
from the other, while the whole had the feeling of soft cartilage. 
The opening from the ureter into the bladder was very apparent. 
I drew a blow-pipe a quarter of an inch thick very easily through 
it; and it could have been considerably more dilated. 
The opening from this ureter was twice as large as from the other; 
but each was very distinct, and near to the other; and there was 
no particular or other formation at their orifices to prevent any 
thing from flowing backwards or forwards. 
The bladder was small and contracted, and its united coats were 
about three-eighths of an* inch thick—the mucous coat was one- 
eighth, and soft and rugous. 
The vein of the kidney, when laid out flat, was an inch wide, and 
five inches long from the vena cava. The artery was half an inch 
wide and three inches long from the aorta.
