He then withdrew from the abdominal cavity a large portion of 
an enormous swelling filled with fluid which burst under press¬ 
ure of the hand. The swelling was a kidney. He removed af¬ 
ter this a second similar swelling. The two kidneys together 
were of the circumference of four times a man’s head. The fluid 
contained in both kidneys amounted to 15 litres. That delivery 
then proceeded without difficulty is easily understood.—

The Best Methods of Anesthesia for Domestic Ani¬ 
mats. —As a result of the interesting labors of G. it has been 
made clear that with few exceptions, anaesthesia in veterinary 
medicine ought to be more extensively employed. The best 
methods are : 1. CHC 1 3 narcosis. This is the least safe and may 
be fatal. The best procedure according to G. is to let the animal 
breathe the CHC 1 3 exclusively through the mouth, always plug¬ 
ging up the nostrils. 2. The mixed methods of atropine and 
morphine with CHCL, and morphine and chloral with chloro¬ 
form, can be used with less danger. The former method has the 
disadvantage of causing longer sleep than one would wish, also 
causing unconsciousness or faints. The latter, if the chloral is 
pushed too far can be attended with serious consequences. 3. 
Mixture of ether and chloroform. It is more correct—and less 
dangerous—to increase the potency of the ether by the addition of 
chloroform than to diminish the dangers of chloroform narcosis 
by the addition of ether. The mixture of ether and chloroform 
is always—in order to avoid accidents—to be preferred to pure 
chloroform.— (Schweiz. Archiv. fiir Thierhlk.)

CEsophageat Obstruction in a Slut [By Mr. Gallier] * 
—This is a very interesting record of a fox-terrier of great hunting 
value operated upon once for a fibroma of the mammae. A year 
after suffering with a mild trouble. She had enjoyed good health 
until lately. She refused her ordinary meal, ate grass and vomited 
' by intermittence. If she drank she vomited ; whatever she took 
was rejected by the mouth. The author was called in consulta¬ 
tion, and found her with high fever, the flank contracted, the intes¬ 
tines empty, the respiration quiet, breath foetid ; palpation did 
not reveal the presence of foreign bodies in the intestinal tract, 
yet in the presence of the constant vomiting and the absence of 
foreign substances in the intestines, a diagnosis was made of ob-
