d of the first period the nitrogenous fed hens had laid
forty-three eggs and the carbonaceous fed hens had laid twenty. During
the next twenty-five days the former laid thirty and the latter six;
during the third period the former laid six and the latter not any.
From this time on no eggs were received from either group. The decline
in egg production was probably due in large part to the fact that the
hens began to moult during the second period, and continued to do so
during the rest of the experiment.

The eggs laid by the nitrogenous fed hens were of small size, having a
disagreeable flavor and smell, watery albumen, an especially small,
dark colored yolk, with a tender vitelline membrane, which turned
black after being kept several weeks. While the eggs of the
carbonaceous fed hens were large, of fine flavor, of natural smell,
large normal albumen, an especially large, rich yellow yolk, with
strong vitelline membrane, which was perfectly preserved after being
kept for weeks in the same brine with the other eggs.
