the organism. Its proliferative power, which is revealed under 

 favorable conditions, is well established, also its intracellular 

 digestive capacity. Though this digestive property of the 

 mesenchyme has been recognized as widely distributed in the 

 animal kingdom, it has not yet been made an object of special 

 inquiry in relation to the equally widely distributed resistance 

 against heteroplastic grafting. Researches along these lines 

 promise to reveal new facts which may bring a better under- 

 standing of the special case of the digestive activity exercised 

 by the adult splenic mesenchyme of the fowl on the cells of two 

 mouse tumors, the Ehrlich sarcoma and the Crocker Fund 

 sarcoma no. 180, a process which at present stands as a unique 

 phenomenon.
