generation. These conditions were, therefore, the result apparently 

 of a hemorrhage of such an extent as to distend the corpora adiposa 

 out of all ordinary shape. 



A further examination of the frog with a view to determining the 

 cause of the hemorrhage showed a small collection of blood on the

dorsal side of the coelome just beneath where the ileum joins the last 

 vertebra. The ileum had been broken and probably in the process of 



breaking caused the 

 hemorrhage. 



In order to ade- 

 quately stain the tis- 

 sues of the corpora 

 adiposa, it was neces- 

 sary to remove the 

 excess of corpuscles. 

 This was accomplished 

 by freely washing the 

 sections in water. Fig. 3 

 shows the conditions 

 of the tissues. On the 

 outside of the capsule 

 there is a well marked band of connective tissue; and this same tissue 

 although less compact forms the main frame-work of the corpora. The

 scattered. There are numerous nuclei in the connective 

 tissue. Some polynucleate phagocytes are shown.
