REVIEWS AND EXCHANGES, 
Whose Home is the Wilderness. By William J. Long. Illustrated by Charles 
Copeland. 8 in. x 5I in. Pp. 230. Ginn and Co. Price 5s. net. 
Every naturalist — every student, that is, of living beings as opposed to the 
mere anatomist — has probably realised the main thesis of this series of “ Studies 
of Wild Animal Life ” by the skilful pen of that born ob.server, Mr. Long, 
namely, that apart from specific characters, animals exhibit individuality, 
psychic if nothing more. That his tales have a philosophic purpose in no way 
detracts from the interest of the author’s narratives ; his animals live : and their 
surroundings are no less vividly set before us, whilst many of the illustrations 
are charming. 
Filial Natural History Essays. By Graham Renshaw, M.B. Illustrated. 
9 in. X 5J in. Pp. 225. Sherratt and Hughes. Price 6s. net. 
We are sorry to see the title of Dr. Renshaw’s third volume. It completes, 
as he says in his Preface, a series of sixty essays dealing with mammals, 
especially those seen in Zoological Gardens, “from the combined standpoint 
of the zoologist and the historian,” illustrated by an excellent .series of photo- 
graphs taken by the author. There are, however, many more mammals — to 
say nothing of other animals — for the learned doctor’s pen and camera, so that 
we hope we are not to part company permanently. Though antelopes and other 
African forms predominate, the subjects of this volume are in no way less 
interesting than those of its predecessors, and many visitors to the Natural 
History Museum in the Cromwell Road will be glad to have the representation 
of the case of polar animals in winter dress, which the author names “ The 
White Company.” 
Some Nature Biographies ; Plant — Insect — Marine — Mineral. By John J. Ward. 
With upwards of 200 Illustrations from photographs by the Author. 7J in. 
X in. Pp. 307. John Lane. Price 5s. net. 
We sometimes think that photographic illustration is overdone in quantity 
and misapplied in its subjects. To observe for oneself such biographies as Mr. 
Ward here records, such as those of the White Admiral, Brimstone, Swallow-tail 
and Cabbage-White Butterflies, a Hydra, a Horse-Chestnut Bud, a falling leaf, 
or the Mildew of Wheat, is a liberal education ; and to photograph them is 
a technical feat and secures an interesting record of one’s observations ; but 
to look at some one else’s photographs instead of the things themselves is far 
less valuable. Photographs of nearly opaque objects, such as not a few of the 
botanical subjects in this volume, are, we think, much less instructive than 
drawings. The skilled draughtsman can render relative values of light and 
shade far more intelligibly than can the camera. Mr. Ward has done his work 
excellently both with pen and camera, and the twelve views of the same land- 
scape at monthly intervals, which attracted our attention at the Royal Photo- 
graphic Society’s Exhibition, are a delightfully novel feature and in themselves 
worth the whole price of the volume. 
Guide to the Specimens of the Horse Family {E]uida) exhibited in the Depart- 
ment of Zoology, British Mu%eum (Natural History). By R. Lydekker. 
Illustrated by 26 Figures. . in. x 5J in. Pp. 42. Price is. 
It is now a good many years ago since Huxley, in calling attention to the 
new discoveries which tended to fill up so many of the gaps which Darwin had 
acknowledged in the palaeontological record, insisted on the fossil Equidae as 
a demonstration of the theory of evolution, or descent with modification. Since 
that time the feet and teeth of this series have become familiar illustrations 
of such evolution. Evidence has been accumulating as to Pleistocene forms 
in South America, the wild Mongolian horse or Tarpan of the Kirghiz Steppes, 
the various geographical races of the allied Zebras, and the “ reversionary ” 
characters of domesticated hybrids ; while Professor Ridgeway’s recent elaborate 
study of the Arab and the application of Mendelian principles to the rjuestion, 
have invested the Stud-book with a new scientific interest. It is, therefore, 
most fitting that a special series of specimens illustrative of this group should
