emains to be said. It should be unnecessary to repeat that in
pointing out literary defects and mistakes, we do not touch the honour
of the writer in any way. How can one measure the weight of a life-
long prejudice, or determine its influence upon conduct or opinion?
"Tout comprende est tout pardonner." Within a few weeks, the author of
"Animal Experimentation," if living, will enter upon his eightieth
year. The errors of judgment, the inaccuracies of statement, the
tendency to exaggerate utility--these and all other literary defects
of the volume before us must be recognized and deplored, but they
should be ascribed only to causes which do not affect the honour of
the man. We may be confident that after he has passed away, the world
will quickly forget the too zealous defender of unrestricted
vivisection, and remember, finally, only the wise teacher, the skilled
surgeon, the trusted friend.

APPENDIX II

In the acquirement of knowledge concerning vivisection, and for the
prevention of abuses, it is essential that in every institution where
experiments are performed a register of all animals received be
carefully and accurately kept. Each one should have a serial number,
under which all particulars should be entered. The book used for this
purpose should have printed in the first column of each double page
the required details concerning which a record is to be kept; the
blanks should be written in ink by someone responsible for its
accuracy. Some such form as the following outline might perhaps be
used for such register:

REGISTER OF ALL MAMMALIAN ANIMALS RECEIVED FOR EXPERIMENTATION IN THE
CARNEGIE LABORATORY DURING THE YEAR 1920.
