little book is designed to express, as the preface states, “the 
family bond uniting all living things, as we use the term, ‘ Natur 
and her works,’ to embrace all organic and inorganic phenomena’ 
Although British animals are referred to wherever possible, yet 
the book will be found to be most agreeable reading by our young 
naturalists, boys and girls. We have never met with a book bet 
ter calculated to interest the young, while it is written froma 
high standpoint. After the youthful reader has read this, and 
“Winners in Life’s Race,” by the same author, he will be pr 
pared to understand the evolutional questions which will com 
up in after reading and study. As it is, the transition from olè 
fashioned books about animals to the more advanced ones, piè 
pared from an evolutional standpoint, is so sudden that the reade 
is sometimes thrown off his balance. The tone of the a 
of “ Life and her Children,” while liberal, is also reverential. 
The illustrations of the marine animals have been prepared by 
Dr. Wild, artist of the Challenger expedition ; they are sketchy 
and attractive, though not always well engraved; but they a 
valuable to the young reader from showing the creatures e 
roundings of water, rock and ocean bottom. The drawing)” pi 
the insects are indifferent, as are the lithographic plates. ' 
book will be excellent reading in connection with school work. f
