116 THE CANADIAN ENTOMOLOGIST. 



This work of 876 pages contains all ilie information necessary con- 

 cerning the forms, occurrences, life liistory in relation with man of his 

 various animal friends and foes, and the curative and preventative meas- 

 ures against their attacks. The newest discoveries of workers in this field, 

 and original researches by the author are recorded, and 477 figures, en- 

 graved with scientific accuracy, show the appearance of the different 

 mammals, birds, insects, snails, and worms, the details of their structure, 

 and many devices for resisting the injurious kinds or assisting those that 

 war against the latter and are thus precious allies of the farmer and 

 gardener. 



The first 30 pages are devoted to considerations on the causes of 

 occurrence of obnoxious animals, and on the general means of protection 

 against them. Then So pages treat of mammals from the bear to the 

 mouse and the bat, 120 of birds, 460 of insects, 130 of snails and worms. 

 The depredations of insects, which have been particularly studied by Dr. 

 Bos, are especially dwelt upon. 



At the end of the book are tables of the animal pests arranged accord- 

 ing to the place where they live. This table is most useful, for, with its 

 aid, anyone who has found any form of animal life preying on man, cattle, 

 domestic animal, tree, or plant, or in granary, barn, or house, and wishes 

 to know its name, habits, the nature of its ravages, the remedies against 

 it, etc., can with very little trouble find the page in the volume where the 

 desired information is given. 



For instance, the first item of this table is as follows, with reference 

 for each animal to the page in the book : — 



Bee, bee hive : — Foxes, marten, polecat, bear, honey-buzzard, tits, 

 occasionally other bird species; — spiders ; — wasps ; — the brown bee louse 

 (Braula coeca, a winged louse) ; — the so-called black bee louse (larva of 

 an oil beetle), which, however, leads usually its cuckoo life only in wild 

 bees' nests ;— bee moths, wax moths ; bee-beetles j — earwigs. 



Similar lists follow for cat, cattle, dog, domestic birds and eggs, goat, 

 horse, man, pig, rabbit, sheep. 



The references to apple tree pests are arranged under the different 

 heads : In roots, in wood, under bark, in bark crevices, on and in buds, 

 on young shoots, on one year's twigs, on buds and leaves, in the fruit, 

 ravagers of the fruit ; and similarly for all common trees and plants of 

 field, garden, or forest. J. A. Guignard, Ottawa.
