B.) 



Briefly summarized, the urine is almost free from calcium ; the feces 

 contains enormous amounts; there is a marked negative calcium balance. 



The urine was always poor in calcium and the feces high in calcium 

 whenever they were examined. The negative calcium balance may 

 possibly not be continuous. The conditions may be similar to those in 

 osteomalacia ; in this condition there is a long continued loss of calcium 

 with negative calcium balance, which gradually becomes less, until in the 

 later stages of the severe cases, the body stubbornly retains an irreducible 

 minimum of calcium, and calcium balance is again reached but on a lower 

 plane. 



There is further evidence for the belief that the failure to grow is asso- 

 ciated with a disturbance of the calcium metabolism especially. As a
