The amounts of total phosphorus excreted and of fecal phosphorus 

 increased with the quantities of phosphorus and protein fed, but the 

 amounts in the urine remained practically constant. 



The data for the different forms of phosphorus in the feces, the total 

 phosphorus in the urine, and the total phosphorus stored in the body, 

 expressed in percentage of the total phosphorus ingested, are given in 

 Table XIV. 



Table XIV. — Different forms of phosphorus in the feces of Iambs, the total phosphorus 

 in their urine, and the total phosphorus stored 



[Results expressed in percentage of total phosphorus ingested] 



It is evident from the data given in Table XIV that, on an average, 

 89.4 per cent of the total phosphorus ingested by the lambs was excreted 

 in the feces. On an average, 75 per cent of the ingested phosphorus of 

 the feeds was excreted in the feces in a form soluble in 0.2 per cent 

 hydrochloric-acid solution, while 69.5 per cent of the total phosphorus 

 consumed was excreted in the feces in the inorganic form. 



On account of the small number of animals in each group and the 

 marked individual differences in the data for the different forms of 

 phosphorus in the feces, the total phosphorus in the urine, and the total 

 phosphorus stored in the body expressed in percentage of the total 

 phosphorus ingested, it is impossible to make out significant group difter- 

 ences due to the differences in the quantities of protein and phosphorus 

 ingested. 



The data for the percentage distribution of the different forms of phos- 

 phorus in the feces in percentage of the total phosphorus are given in 

 Table XV.
