The occurrence of multilocular fat cells in the perirenal fat 



of man.

While a number of writers 1 have called attention to the pres- 

 ence in man of a multilocular adipose tissue similar to the so- 

 called hibernating gland of animals, convincing evidence of the 

 structural similarity between these tissues does not seem to have 

 been brought forth. 



Gross and microscopic preparations of multilocular adipose 

 tissue in the perirenal fat of a new born and of a child \ l / 2 years 

 old are demonstrated with similar specimens from both the white 

 rat and the American marmot, showing great similarity between 

 this type of adipose tissue from all three sources. Its glandular 

 appearance is striking until examined microscopically. The evi- 

 dence indicates that these multilocular fat cells are not develop- 

 mental stages of ordinary fat. 



The history, distribution and functional significance of this 

 brown gland-like fatty tissue leads to the conclusion that there 

 are not sufficient data to warrant taking seriously the suggestion 

 that it may be an endocrine organ of importance in deficiency 

 diseases
