PANCREATIC CALCULI FROM A COW.

viz., cure by resolution . It may be asked, why do you advocate 
slinging in preference to casting? I answer, I do so for 
several reasons, but especially because the animal is soon 
tired of being confined down ; he becomes impatient of 
restraint, commences fighting, and bruises himself all over. 
He also injures his feet in his violence, throws off the 
poultices, rubs off the blisters, &c. ; and you are thus 
unable to attend properly to him. Irritable horses will 
sometimes fight until so completely exhausted that they 
actually expire in their fetters. 
If the above humble remarks shall have tended to the 
elucidation of truth, or in any way to assist in relieving the 
intense sufferings of that noble animal, the horse, when 
labouring under the disease which has formed the subject of 
these papers, my object will have been fully gained ; and the 
knowledge of having so done will be a gratification which I 
shall reckon amongst the greatest I have been permitted to 
enjoy. 
PANCREATIC CALCULI FROM A COW. 
By F. Blakeway, M.R.C.V.S., Stourbridge. 
Dear Sirs, — I beg to send you a few calculi, taken from 
what has been called a cyst, said, by a butcher of this 
town, to have been situated near to the pancreas of a cow, — 
probably it was an enlargement of the duct ; but as I did 
not see them until they were taken out, I cannot speak to 
their exact situation. There were about forty of the calculi, 
and the analysis of four by my friend Mr. W. Stoddart, of 
North Street, Bristol, gives the following result: — 
Carbonate of Lime 1194 
„ Magnesia . . . . - 18 
Phosphate of Lime 3*75 
„ Magnesia . . . . -73 
Organic Matter *82 
Water -16 
17-58 grs. 
We were surprised to find them so infusible, and to 
contain so little animal matter; this being chiefly mucus, 
and a sticky kind of extract, soluble in alcohol. Solution of 
potass had hardly any action on them, and very little was 
dissolved on boiling the concretions in alcohol or ether.
