460 W. M. SMALLWOOD. 



Conklin's picro-haematoxylin many small cells were stained. 

 Each of these has a distinct but small amount of cytoplasm with 

 a definite nucleus in which the chromatin was delicately dis- 

 tributed. These nuclei had a decidedly healthy appearance. 

 After trying a number of stains, I am inclined to interpret them 

 as connective tissue cells. But I am at a loss to understand why

they should be apparently so normal when all of the parts of 

 the muscle cell stained so faintly. From their appearance one 

 might suspect that they were associated with the breaking down 

 of the muscle cells. I have not been able to locate in the litera- 

 ture any evidence that the internal secretions that are believed 

 to be responsible for this breaking down of muscle are the 

 product of any definite cells. It may be that part at least of the 

 secret is discovered in these active connective tissue cells.

 constantly raised and lowered in a regular manner. This simple
