ZOOLOGY. 
Parker and Haswell’s Zoology.!— For many years there was no 
greater need in teaching zoology than a good text-book on the sub- 
ject — one which should treat the subject from a modern morpholog- 
ical standpoint. One need not go back more than four or five years 
to find the time when Sedgwick’s translation of Claus was the only 
such work available. This real need has been met, and perhaps 
more than met, in the last few years by the translation of several 
works from the German, and by new publications in the English 
language. Among the books on this subject which have been 
anxiously awaited by teachers of zoology was the long-promised 
work by Parker and Haswell, which has recently appeared. Parker’s 
text-book on zootomy and on elementary biology were evidence that 
one of the authors, at least, thoroughly understood the needs of the. 
elementary student. Jt may be doubted whether any book in any 
language presents the facts of elementary biology in a more attract- 
ive manner than does Parker’s text-book on this subject; and it 
was to have been expected that the new book on zoology would be 
preéminently a student’s text-book, clear, concise, and attractive. 
In this respect no one will be disappointed with the work. The 
authors show at every step that they are, before all else, teachers, 
and that they know how to present the facts of zoology in a way 
which, even to the laity in such matters, is intelligible, interesting, 
and instructive. 
In spite of its size the authors expressly affirm that the work is 
addressed to the needs of elementary students, but it is to be feared 
that both the size and the cost of the work will effectually prevent its 
coming into very general use among persons of this class. Almost 
all recent English works on zoology seem to show that it is no longer 
possible to condense into a single volume the elements of the whole 
Science. On the other hand, some notable German text-books on 
this subject are much more limited in extent, while no less accurate 
and satisfactory ; e.g., the works of Boas and Hertwig occupy, respec- 
tively, 578 and 576 pages, and few, if any, better text-books on zoology 
can be found in any language. Hatschek’s work is unfortunately 
Still a fragment, but where is there another such a text on the field 
which it covers? These German works show that it is possible to
