DISEASE OF THE SPLEEN IN CATTLE. 141 
A part of the liver was of a greyish colour, and softened in 
substance. The gall-bladder was unusually full of bile of a 
blackish green colour, and very thick. The urinary bladder 
was about half full of fluid, of the same colour, but not quite 
so thick as that in the gall-bladder. The substance of the 
spleen was reduced to a semifluid state, and was of a livid 
red colour, and weighed 14 lb. The rumen and maniplus 
were full of ingesta ; the epithelium was easily separated, and 
the surface from which it was removed had a red streaky 
appearance. A portion of the intestines, about a foot in 
length, contained a quantity of fluid resembling the state to 
which the spleen was reduced. 
The other beast, which I also had the opportunity of seeing, 
presented precisely the same appearances, except the spots 
on the bowels. After having satisfied myself with the ex- 
amination of the dead, I accompanied the owner to the field 
to see others that were living, and among them I thought I 
saw one a little ailing, but could scarcely speak positively, as 
the beast was so much tormented with the flies, which the 
oldest man cannot remember ever being so troublesome before. 
I told the owner he had better watch this animal in the even- 
ing when the flies were gone, which he did, and about 9 p*m. 
1 received a message to attend, as there were three more 
animals ill, namely, the one I had pointed out and two others. 
When I arrived, the symptoms presented were a staring 
coat ; backs arched, with a stiffness and unwillingness to 
move ; pulse about 60, and rather oppressed ; and a little 
saliva flowing from the mouth. I bled two of them (the worst), 
and gave all of them a dose of aperient and febrifuge medi- 
cine, and left them in the yard for the night. 
The next day, before I arrived, one had died, and another 
being nearly dead, was killed, as was also the other. Now, 
as there appeared to me to be but little chance of a cure being- 
effected after the disease had developed itself, I advised the 
owner to have all his cattle attended to, so that w r e might, if 
possible, prevent any more from falling into this state. lie 
did not, however, consent ; when some few days afterwards 
my services were again required to five cows, two of which 
had failed in their milk, and were looking very thin. They 
were frequently lying with their heads back upon their sides, 
and the throat was swollen. I gave them as follows : 
1^3 Aloes Barb., ^iiij ; 
Zingib. Pulv., ; 
Potassse Nit., ; 
Magnesise Sulphas, §xij ; 
Pul. Corticis Peruv., ; 
Aquas, q. s. fiat haustus;
