A CASE OF BLACK-WATER. 
Spinal marrow. —At the withers and at the posterior dorsal vete- 
])r 0 e I cut down to the spinal marrow, and laid bare about six inches 
of it in each place, but I found no inflammation or effusion within 
the theca. The exterior membrane was a little discoloured and 
tinged yellow. 
Paunch, —This viscus was sound, and about three parts filled 
with moist food. There was nothing unusual about the appearance 
of it. 
The second stomach had about a quart or two of liquid matter 
in it, of the colour of that in the paunch, but it was much softer. 
The stomach was sound. 
The third stomach was quite filled with food, but nearly three parts 
of it were very soft, and especially so about the canal that leads 
through it. The remaining part was much harder, but not at all of 
that dry hard nature that is found in many cases of staking; indeed, 
I have frequently seen it as bad at slaughter-houses in fat cattle 
that have been killed there. Where the food was the hardest, the 
plaits were covered with a blush of inflammation. 
The fourth stomach was, on its mucous coat, almost entirely 
covered with ecchymosis, and looked severely diseased. It con¬ 
tained about a couple of quarts of liquid, slimy secretion and 
food. 
Intestines. —These were, even on an external view of them, 
diseased, and had a dark blue appearance. On laying them open 
the mucous coat was found to be covered with a secretion of a very 
dark bl ue colour—almost black. It was not one continuous covering 
of this colour, but spotted over in specks from the size of a pin’s 
point to a pin’s head as thick as they possibly could be set, and 
which might have been scraped off with a knife. There was 
scarcely any part tinged with bile. 
The gall-bladder contained about a pint of bile, of the thick¬ 
ness of good cream, and of a dirty yellow colour. On viewing 
the substance of the liver, one-half looked tolerably sound, and was 
so on cutting into it; but the other part had an unsound appearance 
and was of a clay colour, and on cutting into it appeared to be much 
diseased. Itwasof the same colour throughout, and a great deal of 
it was very soft and in a decomposed state. 
The spleen was a little engorged, and on making an incision into 
it I could readily force the whole of the blood out, leaving its cel¬ 
lular structure beautifully shewn. The blood was of a brownish 
colour, and almost putrid. 
Kidneys. —One of them Avas of a paler colour externally than 
natural, but internally it Avas more firm and redder. The other 
appeared diseased as it lay in its situation, and, on stripping off its 
tunic, Avas of a dark blue colour Avhere the bowels must have pressed
