third (final) examination after studying for one winter and one 
summer session in any British veterinary college—the only pro¬ 
viso being that the time spent in obtaining the foreign or colo¬ 
nial diploma be equal to that usually spent in studying for the 
subjects of the first and second examinations in British schools, 
i. e., two winter sessions of twenty-two weeks and one summer of 
eight weeks duration. 
HOSPITAL RECORDS, 
REMOVAL OF THE LATERAL CARTILAGE IN TWO CASES OF 
QUITTOR. 
By W. D. Critoherson, D.V.S., House Surgeon Amer. Vet. Col. Hospital. 
. This operation was first performed by Lafosse, in 1750. At 
the present time, with but few exceptions, it is only employed 
after all other means of treatment have failed. But it is rapidly 
gaining favor with the profession, and will undoubtedly soon 
receive from the educated veterinarian the attention which it so 
justly merits. 
“ It is essential to avoid injury to the coronary band, the podo- 
pliyllous tissue, the lateral ligament, and the synovial capsule of 
the articulation.” The two operations which I have to record 
will illustrate the benefit derived—in one a chronic case, in the 
other, a case which was the result of a suppurative corn. In 
both, complications arose. In the first they were slight, while 
in the second case they were more serious. 
Case No. 1.—A gray mare, eight years of age, fifteen hands, 
one and one-half inches in height, and weighing about 1150 
pounds. 
This animal was brought to the hospital on the 16th of May, 
very lame on the near fore leg. Upon examination (the shoe 
had been removed) found an enlargement the size of a man’s 
closed hand, situated on the outside of the coronet, in the region 
of the cartilage which limits the lateral and posterior portion of
