ADIPOSE TISSUE. 25 



of minute vesicles, varying in diameter up to -^^ of an inch, 

 filled with oil, and imbedded in groups in connective tissue. 

 Sometimes a nucleus can be detected at the side of the vesicle. 

 The mode of development appears to be that one or more 

 minute globules of oil occur at first in the interior of a con- 

 nective-tissue-corpuscle, and that the oil goes on accumulating, 

 pushing before it the substance of the corpuscle, which sub- 

 sequently is so altered in appearance and consistence, as to 

 form the wall of the vesicle or adipose cell. Adipose tissue, 

 and the connective tissues o-enerally, are but scantily sup- 

 plied with blood-vessels
