This second edition shows improvements in comparison with the already
very valuable first edition. It is therefore a pity that the photographs are reproduced
so unsatisfactorily. On this account we should like to recommend that
the ne.xt edition again be printed on better paper (which would however make
the book more expensive) or that another technique be used.
The new chapter on comparative embryology of the vertebrates, in which
several developmental steps are given of the development of the frog, chick,
pig and man, in the form of drawings of sections, is very well prepared. The
distribution of the figures on the successive pages cannot however be considered
a great success. It would have been clearer and easier to arrange the
figures simply according to the successive stages, since it is essentially the cross
references at the beginning and the end of the description of each figure which
form the actual key for comparison.

"GRUNDRISZ DER ALLGEMEINEN ZOOLOGIE"
ll»h edition, 1955
by A. Kuhn Georg Thieme Verlag, Stuttgart
281 pp. with 223 figs Price: 16,50 D.M.
This concise textbook of Zoology for premedical students will form a guide
into the enormous variety of forms and functions in the animal kingdom, and
will show the general principles upon which its structure and function are
based. The tenth edition has been changed and extended in many respects;
the eleventh edition however shows only some corrections and small additions.
The book begins with an extensive introduction into the various phyla, classes
and orders of the Invertebrates and Vertebrates. In the various groups of
Invertebrates special attention has been paid to the parasitic forms, with their
pathological significance. An extensive chapter has been devoted to general
physiology in relation to morphological structure, after which the general development
of the organisms has been described, with special emphasis upon the
genetical aspects. Finally, some data on ecology and phylogeny have been
briefly given.
The concise, but comprehensive treatment of the various chapters and the
very instructive form of the illustrations allow this textbook completely to fulfill
its purposes. We should like to recommend it warmly not only to premedical
students — the text might be too extensive for the premedical teaching in many
countries — but also to elementary students in biology. The list of references
at the end of the book opens the way to more detailed studies of special
subjects.

This sixth edition has become essentially a new book, since it has been
