by Professor L. E. Eastham Formerly Professor of Zoology in the
University of Sheffield Most books are written with the intention of
supplying some particular need, but few end with such single purpose.
Mrs. Mellanby's is no exception, for while the author planned this work
to serve as a guide to the school pupil, which function it fulfils in an
admirable way, it will also prove of value to the teacher, the
university student and the amateur naturalist. While it may be argued
that it is not the function of the Uni- versities to teach Natural
History in the commonly accepted sense, it will always be the aim of
Zoologists to know more about animals, what they are and do, where they
live and why they live in particular environments. It is unfortunate, in
view of the fact that the majority of students of Zoology enter the
teaching pro- fession, that the increasing load of instruction in
morphology, physiology, cytology, genetics, evolution and the like
frequently makes a personal study of animal life in relation to
environment almost impossible. The fortunate ones visit the sea for a
fort- night's course in Marine Ecology; the others take posts in schools
without even this respite and set about converting their academic
learning to a school curriculum. The result is an undesirable and often
slavish imitation of university method in the school class- room.
