The B, O. U. List of British Birds (1915) might, however, 
have been consulted with advantage, if only for the sake of 
that uniformity whicli we are all striving to reach. 
At the time of his death Ogilvie was engaged in writing 
an important ornithological work which Avill now, unfor¬ 
tunately, never be published. If his “ Field Observations 
on British Birds” are anything to judge by, ornithology 
has, by the author's untimely death, been robbed of an 
exceptionally valuable contribution, even in these days of 
accurate observers and accomplished writers. 
Ornithologists and sportsmen alike owe a debt of gratitude 
to Mr. Henry Balfour, who has edited this volume “as a 
tribute,” we are told in the Preface, “to one whose death 
involved a great loss to ornithological science,” how great 
a loss only those who read Mr. Ogilvie’s book for themselves 
can properly appreciate.— D. A. B.

This work is based on a series of lectures delivered by 
the author in Aberdeen in 1917, and deals at length 
with the effects produced by man and his manifold works 
on the various forms of animal life. The author endeavours 
to trace the different ways in which man’s power has worked 
and is working, and to realize to what degree a fauna of 
to-day owes its character and composition to his interference 
with nature. 
For the purpose of this study a fauna of a manageable 
compass was necessary, and Scotland w^as found to be most 
suited to fornf a basis. An introduction deals with the 
arrival of. man in Scotland, which did not take place till 
comparatively late, as the whole country appears to have 
been covered with an ice-sheet long after man inhabited the 
south of England, and the earliest Scots belonged to the Neo¬ 
lithic period of culture. Part I. deals with the deliberate 
interference by man with animal life under the headings
