presenting a preponderance of Gram-positive coccoid 
organisms. His appetite was fair and he showed marked 
craving for lime, eating plaster from the walls when he 
could get it. Because of this desire for lime he was given 
a salt mixture to see if it would have any effect on the 
bone condition. The mixture used was the following : 
NaCl 0.874 grams 
KCl 0.548 grams 
CaH(PO) H2O 3.608 grams 
Ca lactate 0.386 grams 
Mg citrate 0.848 grams 
K citrate 1.953 grams 
This mixture the animal ate with avidity and seemed more 
comfortable ; other than that no change was noted. 
An inorganic metabolism examination was attempted 
on the ordinary diet and the diet plus the salt mixture. 
Under the circumstances at our disposal tliis was not 
entirely accurate but showed such marked variation from 
the control animals examined — normal and osteo- 
malacic — and such marked correspondence on the four 
separate four-day periods, of each intake that it seemed 
acceptable. The result of this investigation on the first 
series of four four-day periods was :

0.0463 =0.0177 retention 
0.07 =0.084 retention 
0.17 =0.026 loss 
The result on the higher salt content was practically the 
same, the retention being in proportion slightly less. The 
diet for these small monkeys is two apples, two bananas, 
six small sweet potatoes, with a lump of boiled rice about 
the size of an egg. The content of this diet has been 
found very low in calcium, phosphorus, sodium, chlorine 
and iron, while potassium, magnesium and sulphur were 
high. To this diet lime water was added to increase its 
inorganic content.
