Page 3 - ANIMAL MICROLOGY PRACTICAL EXERCISES IN ZOOLOGICAL MICRO-TECHNIQUE FOURTH REVISED EDITION BY MICHAEL F. GUYER

vi Preface to the First Edition

that the student will find the methods recommended all good ones
which will yield satisfactory results.
In Appendix D some directions are given for collecting and prepar-
ing material for an elementary course in zo~logy.
It is hoped that the volume will prove of use: (1) as a class text-
book; (2) as a guide to the independent individual worker (teacher,
physician, college or medical student, or novice); (3) as a reference
book for teachers, in the preparation of material for courses in elemen-
tary zo~logy, histology, or embryology.
In the matter of expressing his obligations the writer is at a loss to
know just what to do. Many of the methods in microscopical tech-
nique have been handed down tradition-wise from one worker to an-
other until their origin is unknown; they are the accumulated expe-
riences of several generations of workers. Furthermore, many points
have been absorbed, as it were, by the writer, from fellow-workers in the
Universities of Chicago, Nebraska, and Cincinnati, respectively; con-
sequently the obligation cannot be specifically expressed. Where the
name of the originator of a method is known, due credit has been given.
The books to which the author is most heavily indebted are the vol-
umes of Gage and Carpenter, already mentioned, Lee's Microtomist's
Vade-Mecum, Whitman's Methods in Microscopical Anatomy and Em-
bryology, Hardesty's Neurological Technique, Foster and Balfour's
Elements of Embryology, Minot's Laboratory Tert-Book of Embryology,
Huber's translation of the Bohm-Davidoff Teet-Book of Histology,
St~hr's Tert-Book of Histology, Mallory and Wright's Pathological
Technique, Bausch's Manipulation of the Microscope, and the Journal
of Applied Microscopy. Grateful acknowledgment is also made to the
various manufacturers of microscopical instruments and appliances
for the loan of most of the cuts which have been used in this volume.
