RUPTURE OF THE COLON.

such subjects as may be at issue. Such opinions must be 
regarded with favour, and would be of great assistance to 
the veterinary witness. I will now just dot down a few 
questions to exemplify my meaning, viz. : 
Do you consider corns to constitute unsoundness in an 
otherwise healthy foot, provided no lameness be present ? 
Do splints, or other bony deposits on the fore-legs, in your 
opinion, constitute unsoundness when no lameness is present ? 
Do you consider thorough-pins, wind-galls, or other bursal 
enlargements, not producing lameness or impeding action, to 
constitute unsoundness ? 
Do you believe a horse to be unsound, having a curb of 
long standing, when no lameness is present ? 
Is a horse unsound, in your opinion, having an opaque 
spot upon the cornea, when the internal structures of the 
eye are not involved ? 
This, then, is simply the outline of my plan. I do not 
wish to dictate or to consider that this is the best that can 
be adopted to meet the requirements of the case, I merely 
suggest this. 1 shall only be too happy to aid in a better 
one ; and as funds will be necessary for carrying out any 
plan, I shall be delighted to contribute as far as it is required 
of me.

Manchester. 
On Monday, July 27th, about one o'clock, p.m., an aged,

examination, I found the pulse to number fifty beats in the 
minute, and to be intermittent; the mouth dry and clammy; 
the visible mucous membranes injected ; the extremities 
cold; the respiration increased, and a peculiar careworn, or 
anxious expression of countenance present, accompanied with 
frequent sighing. I administered a draught composed of —
