RESISTANCE OF THE RED GLOBULES OF THE BLOOD ON 
ANIMALS OPERATED BY THYROIDECTOMY. 
By Bottazgi. 
Thyroidectomized dogs, and, especially those which have 
the classic cachexia, live some fifteen days; there is in the be¬ 
ginning an increase of the resistance of the hematics, due 
probably to the destruction of the weakest elements. Later, 
when the dogs have convulsions, clonic and tonic spasms with 
shiverings, the resistance diminishes some, on account of the 
muscular efforts and the respiratory insufficiency, and again 
on account of the alteration of the organic metabolism follow¬ 
ing the operation. This diminution in the resistance is not 
to be compared to that due to the action of the toxic of the 
blood ; these toxics, which are formed in the strumiprivarous 
cachexia, have a lesser action upon the blood. The resistance 
of the red corpuscles varies with the breeds of dogs. In dogs 
that are kept fastened, the diminution of globular resistance 
appears after the first week, and becomes more and more 
marked until the twelfth day of the fast .—Revue des Sc. Med. 
SOME OF THE EFFECTS OF THYROIDECTOMY ON ANIMALS. 
By J. L. Smith. 
In some animals, cats and dogs, the operation has for re¬ 
sults rapid symptoms of irritation of the nervous and muscu¬ 
lar systems, followed most commonly by death. And again, 
in man than monkeys, the accidents are slower in their mani¬ 
festations as those of myxodema. There is a great variety of 
effects in the different species, and even in the same species. 
There is, however, a general type with a more or less marked 
degree, i. For instance, a muscular shivering when the ani-
