The specific gravity of fresh eggs from the different pens was: 
Pen No. 1, average of forty eggs, 1.088. 
Pen No. 2, average of twenty-four eggs, 1.086. 
Pen No. 3, average of eleven eges, 1.095. 
Pen No. 4, average of thirty-seven eggs, 1.091. 
There was no appreciable difference in the specific gravity of 
eggs from pens of the same breeds differently fed. There was a 
greater difference in regard to breed, the brown shell eggs 
averaging 1.087 specific gravity and the white shell eggs averaging 
1.092. 
There was a slight difference in the chemical composition of 
egos from different pens, as can be seen from the table. The 
_ most noticeable difference was in the ash. Eggs from No. 3 con- 
_ tained twice as much as those from No. 4 (the same breeds fed 
differently). 
The chief difference between eges from No. 2 and No. 4 (differ- 
- ent breeds, fed the same) was in the per cent of water, those 
' from No. 2 having less, making the per cent of other constituents 
_ somewhat higher. Other results in accord with this observation 
will be given later. 
The per cent of shell in fresh egg was: 
Pen No. 1, average of 40 eggs, 9.98 per cent shell. 
Pen No. 2, average of 43 eges, 9.95 per cent shell. 
Pen No. 3, average of 21 eggs, 10.78 per cent shell. 
Pen No. 4, average of 50 eggs, 10.86 per cent shell. 
_ There was some difference in per cent of shell in regard to 
breed, the brown shell eggs averaging 9.96 per cent and the 
white shell averaging 10.82 per cent. The different feed had no 
effect on amount of shell, as the average for 1 and 3 was 10.38 per 
cent and for 2 and 4, 10.40 per cent. 
It would appear from this result that the source from which 
the fowls obtained material for the egg shell was independent of
