my work in cytology has been done in his
Department and I owe much to his advice and
encouragement.

THIS book is founded on the experience gained
in giving nine annual courses in cytological tech-
nique to advanced students in the Department of
Zoology and Comparative Anatomy at Oxford. I
want to express my gratitude to Professor E. S.
Goodrich, F.R.S., in whose Department it has been
my privilege to work since I was an undergraduate,
and to Dr. H. M. Carleton, from whom I first began
to learn cytology fourteen years ago. I cannot
omit to mention my indebtedness to Mr. Frank
Sherlock, whose manipulative skill in microtomy
is well known to all Oxford zoologists.
