kidneys of three freshly-killed deer, and of several hares, filled 

 with free fat- globules, and the epithelium similarly filled, while 

 scarcely an isolated fat-globule could be seen in the true tubular 

 substance or in the contents of the bladder of these animals. 

 Since these animals were perfectly healthy, and had certainly 

 taken no fatty food shortly before their death, these observations 

 to a certain degree oppose Lang's view, according to which the 

 amount of fat in the normal kidneys is dependent upon the use of 

 fatty food. At all events the subject requires further investi- 

 gation, notwithstanding Lang's careful observations. On a recent 

 occasion I could find no fat in the kidneys of a deer : could those 

 three animals have been in a special state of development ? 



[We may here notice the investigations of Professor Beale* in 

 reference to the amount of fat in the human liver arid kidney both 

 in health and disease.
