NOTICES OF NEW BOOKS. 857 
written about organs rather than about groups of animals; but 
he has added an Index, in which the various parts of an animal 
are collected under its name; so that the student who desires to 
use the volume as a zoological text-book will have no difficulty 
in selecting the portions of the chapters which bear on a 
particular form or set of forms. 
A noticeable feature in the book is that all important bio- 
logical terms which precede the definitions given of them are 
printed in bolder (Clarendon) type. These, in point of fact, 
are the material words which would be certain to be underlined 
by the student, were he not by this device saved the trouble of 
doing so. Another commendable feature is that the author gives 
the names of his authorities for important statements, a practice 
which we should like to see more generally adopted, especially when 
such statements embody the latest results of biological research. 
It too often happens that the writers of text-books, for the sake 
of brevity, condense in a few lines an allusion to some recently 
ascertained fact, and by omitting a reference to the authority for 
the statement, disappoint the reader, who would like to satisfy 
himself on the point in greater detail. 
The woodcuts in this volume, although of unequal merit, 
seem to have been selected judiciously, and sufficiently illustrate 
the author’s remarks. 
The Collected Scientific Papers of the late William Alexander 
Forbes, M.A. Edited by F. EK. Brpparp, M.A. With a 
Preface by P. L. Scuarer, M.A., Ph.D., F.R.S. Royal 8yo, 
pp. 496, with 25 plates. London: R. H. Porter. 1885. 
THe late Mr. W. A. Forbes, as many of our readers will 
recollect, was for three years Prosector to the Zoological Society, 
during which period he brought before the scientific meetings 
many interesting and valuable communications, mainly derived 
from his studies of the animals that came under his examina- 
tion at the Zoological Gardens. These were published at 
intervals in the Society’s ‘Proceedings.’ In addition to these, 
he contributed several papers to ‘ The Ibis,’ and ‘ The Entomo- 
logist’s Monthly Magazine,’ and an important Report on the 
Anatomy of the Petrels collected during the voyage of H.M.S. 
‘Challenger,’ printed in the Scientific Reports of the Voyage,
