As would be expected because of the close relation between the 

 kidney and corpora adiposa and the mutually common blood vessels, 

 the kidney cells were also greatly effected. Figure 6 is a drawing 



similar to Figure 5, although the 

 tubule is slightly larger. The 

 nuclei are not as common and 

 show that there has been an 

 important reduction of the con- 

 stituent parts, especially of the 

 chromatin and granular particles. 

 The cytoplasm is no longer ho- 

 mogeneous but loosely granular 

 and contains many vacuoles. 

 There is an absence of well 

 defined cell walls between the 

 adjacent cells of the tubule. In 

 addition there are numerous 

 plasma-staining masses of ir-
