On this 31st day of March, 1920, before me, the subscriber, personally
came A. B., known to me, and he, being duly sworn, declared that the
foregoing report signed by him is a full, true, and complete statement
of all the animals of the species named therein, which were either on
hand on the first day of the quarter, or which have been received at
the Laboratory of the Carnegie Institute for experimental purposes,
and the disposition thereof, for the quarter-year ending March 31,
1920.

NOTARY PUBLIC.

It is necessary not only to know what animals are received at any
laboratory; we must be able to follow them to the end. Each
individual instructor, professor or assistant-professor, or other
person who performs experiments of any kind should be required to
state what he has done. The following is an outline of a report which
might be made to the Director in charge of the laboratory.
