NON-MASTICATION OF THE FOOD. 
About two days after I visited her again : the wounds on the 
neck were healed without any bad results. I then had her cast 
and properly secured. On proceeding to open the maxillary 
cavities with a trephine of an inch and a quarter diameter at 
the inferior point of the spine of the superior maxillary bone, 
the instrument was much impeded in its operation by the 
turbinated bones, whose cavities were completely filled with 
matter. I next opened the frontal sinus by a perforation at the 
inferior point: the piece of bone came neatly out with the in¬ 
strument, the internal periosteum remaining entire, and on per¬ 
forating which about a quarter of a pint of thick pus came 
away. It was even thicker than that discharged from the nose. 
I next made an opening to the frontal sinus, from the perfora¬ 
tion in the superior maxillary, by directing an instrument upwards 
and backwards, in order to secure a depending orifice for the 
proper evacuation of the matter. I then syringed the cavities 
well out, and let the filly get up. 
The after-treatment was as follows:—The wounds were well 
syringed with soap and warm water, then with water without 
soap ; and after that a little of a lotion, composed of a drachm 
each of acetate of lead and sulphate of zinc in a quart of 
water, was injected into the parts once a day. 
Internally, I gave the oxymuriate of mercury in doses of gr. x, 
increased to gr. xx every other day for about two weeks; I then 
gave the increased dose every third day for nearly two months. It 
was now discontinued for a considerable time, and then resumed 
for another month. Twice I had to enlarge the openings at 
distant periods. There was never the least discharge from the 
nose after the operation. It was about tvvelve months before I 
suffered the lower opening to close. 
Being at Murrall with three of Mr. Dick’s young men as assist¬ 
ants in castrating several colts, I had an opportunity of examin¬ 
ing the mare about a month ago. She had been a year at work, 
and is quite free from disease. The cheek is now but little en¬ 
larged ; the perforations are quite closed up.

An aged bay horse, the property of Charles Stanborough, 
Esq., of Isleworth, was yesterday, June the 28th, driven to 
Windsor. He performed the journey in his usual excellent style.
