nation of the double eolon ; “ it was elearly what is commonly 
termed a dust-ball.” It was broken into small pieces with the 
hands of the operator and the operation ended with the ordinary 
antiseptic measures. The animal lived for nearly a week. At 
the post-mortem a dnst-ball weighing 6 lbs., and measuring i8}4 
by 19^ inches, was found in the large colon at its junction with 
the floating colon. These two cases show that laparotomy is 
not an operation to be undertaken in horses, unless the diagno¬ 
sis is certain, and that even when the greatest care is taken the 
probable sequel is always to be taken into proper consideration. 
Rupture of Both Suspensory Ligaments [By Mr. H. C. 
Jcigger ^.—This case is rather peculiar on account of the loca¬ 
tion where the ruptures of the ligaments wxre said to have taken 
place. It is stated that in both fore legs of the mare in which 
the accident happened “ there were no bones broken, the flexor 
tendons were not ruptured, but merely both suspensory liga¬ 
ments about their middle.” At the time of the accident, the 
mare was trotting gently along under a hedge and the rider had 
only noticed her stumble once before, immediately prior to the 
accident. She gave way at both fore fetlocks and was stand¬ 
ing with her feet in front of her, the soles pointing straight to 
the front, resting, as it were, on the distal end of each large 
metacarpal bone, one of which had pierced the skin and rested 
naked on the ground. The history and the symptoms point 
very much to that lesion which is not uncommon in the United 
States, cases of breaking down, of giving way of the insertions 
of the suspensory ligaments at the great sesamoids, with changes 
in the structure of the bones and the ligamentous tissue also. 
Canine Dentistry. —To Mr. Hobday is due this probably 
unique and interesting case. It is that of a dog, whose teeth 
had almost all disappeared from old age, with the exception of 
four good canines and four carnassial molars. With the assistance 
of Mr. B. Moseley, L.D.S., an impression of the mouth was 
taken, and a plate of platinum, with 24 teeth (6 incisors, 6 
molars and premolars in each jaw), was made. At first the 
animal seemed to object and manifested great discomfort, but 
after two hours did not offer any objection. With his new set 
of teeth, which are taken off every day and cleansed, the animal 
is able to enjoy his meals, eats meat and crunches bones without 
trouble, and in a month he has gained one and a half pounds in 
flesh.— [Jour. Co7np. Path, arid Therap})
