PHOSPHOROUS SUBSTANCES OF THE CELL. 149 



with dilute acids and that it offers a possible explanation of 

 the production of some of the waste products of muscular 

 activity, muscle-nucleon becomes a body of considerable 

 importance and interest, though fresh confirmatory work is 

 required before we can consider its role as a store of 

 muscular potential energy at all satisfactorily determined. 

 One fact which seems to bear against this view is that the 

 amount of it present in muscle is very small, viz., from o'i 

 to 0*2 per cent. Its iron ccmpound carniferrin has been 

 shown by Hall l to be readily absorbed in the small intestine. 

 It may thus to some extent serve as one means by which 

 iron is taken into the body.
