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 the Scots Grey. 
The history of the destruction of the larger birds of prey 
and the Great Auk are told with considerable detail, and 
of the introduction and spread of the Pheasant and Caper¬ 
caillie; the gradual extension of the range of the latter is 
illustrated by a map. 
The work is written in charming style with many quota¬ 
tions from the older writers and poets, and the illustrations 
are numerous and well chosen, and though it is on the larger 
mammals that the effects of maiPs 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 others as full of information and interest.

collection of birds made by a Dutch planter, Heer A. C. F. A. 
van Heyst, in the Deli district of north-eastern Sumatra. 
The country in which the collection was made ranges from 
the mangrove forest of the coast, through the low-lying 
districts planted with tobacco, and thence to the central 
mountainous country, rising to elevations of 4000 to 
5000 feet. Representatives of 242 species were obtained and 
four new forms are described, namely— Macropygia rujiceps 
sumatranus, Bracliylophus chlorolophus vanheysti, Cyornis 
vanheysti , and Buchanga leucophcea batahensis. Four other 
species are recorded from Sumatra for the first time. A good
