The following table shows the per cent of calcium found in the 
ash of each food and in the eggs and the equivalent amount of 
carbonate of lime. In the oyster shells and the egg shells nearly all 
the lime present vi was in the form of carbonate.

It was intended that these hens should have only rain water to 
drink, but through a misunderstanding spring water was given them 
part of the time. The actual amount of water taken by the hens at 
this time is not known, but the amount measured out to them, and 
which they could not have exceeded, gives a limit to the amount of 
lime that could have been obtained from this source. 
This water contained in solution 358.3 parts of total solids in the 
million and 287.3 parts of inorganic matter; 58.2 per cent of the inor= 
ganic matter was carbonate of lime. 
The results obtained during these two periods can best be shown
