PREFACE TO THE SECOND EDITION
The favorable reception accorded the first edition of Animal Mi-
crology has encouraged the author to believe that a second edition, in-
corpora ting some of the many new methods which have appeared dur-
ing the past ten years, would be equally welcome. The general plan of
the book has not been altered (see Preface to the First Edition, on a
preceding page), although changes have been made on nearly every
page, many sections have been entirely rewritten, and two new chap-
ters, one on "Cytological Methods," the other on "Drawing," have
been added. The chapter on drawing has been prepared by Dr. Eliza-
beth A. Smith.
In spite of a determined effort to limit the book to its former size,
it has expanded by over fifty pages. For every method dropped there
seemed to be a host of good new ones demanding recognition. These in
the main, however, have been left to the encyclopedia and the various
technical books and journals listed at the end of the volume. As in the
first edition, the policy has been, not to attempt to give all "best"
methods, but rather to select representative good ones which have
proved their worth by satisfactory tests in American laboratories.
Whatever merit the new edition may prove to have over that of the
earlier one is due in no small measure to the many helpful suggestions
of my colleagues in other colleges and universities. I am particularly
indebted in this respect to Professors C. E. MeClung, R. R. Bensley,
H. MeE. Knower, F. L. Landacre, F. C. Waite, B. M. Allen, George R.
La Rue, Edward L. Rice, F. D. Barker, R. M. Strong, and H. L. Wie-
man, and to Doctors Elizabeth A. Smith and C. H. Heuser.
