of domestication, destruction for safety, food or sport, 

 protection, and the deliberate introduction of new animals. 

 Part II. recounts man's indirect interference with animal 

 life by the destruction of forest, the increase of cultivation, 

 and other minor factors. 



As regards birds, the author traces the history of the 

 Domestic Pigeon in Scotland, and also of two ancient 

 Scottish breeds of fowls, the Dumpy and tlie Scots Grey. 



The history of the destruction of tiie larger birds of prey 

 and the Great Auk are told with considerable detail, and 

 of the introduction and spread of the Pheasant and Caper- 

 caillic ; the gradual extension of the range of the latter is 

 illustrated by a map. 



The woik is written in charming style with many quota- 

 tions fiom the okler Avriters and poets, and the illustrations 

 are numei'ous and well chosen, and though it is on the larger 

 mammals that the effects of man's influence has been mostly 

 felt, it is remarkable how human civilization has affected 

 even the less conspicuous and more humble forms of life. 

 We can thoroughly recommend the book to ornithologists 

 and otlieis as full of information and interest.
