standard of growth. The high protein groups are very closely- 

 equivalent in weight, protein and water content to the 

 standard. The two low protein groups reach two-thirds of the 

 high protein groups with regard to weight, water and protein. 

 The degree of mineral accretion in the high protein animals is 

 significantly different, the high electrolyte group accreting

 which was on an equivalent protein but higher ash-containing 

 ration. In the low protein groups, whether on high or low 

 electrolyte intake, the gain of ash is not significantly different. 

 It is evident that protein intake is a limiting factor allowing 

 exploitation of a high ash intake only on a high protein diet. 

 The low protein, low electrolyte animals show a greater 

 relative and absolute accretion of protein than do the low
