168 Recenthj imblished Ornithological Works. [Ibis, 



The B. O.U. List of British Birds (1915) might, however, 

 have been consulted witli advantage, if only for the sake of 

 that uniformity whieh we are all striving to reach. 



At the time of liis death Ogilvie was engaged in writing 

 an important ornithological work which will now, unfor-

 exceptionally valuable contribution, even in these days of 

 accurate observers and accomplished writers.

 to Mr, Henry Balfour, who has edited this volume "as a

 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.

 with the effects produced by man and his manifold works 

 on the various forms of animal life. The author endeavours 

 to trace the ditterent ways in wliich 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 «as necessary, and Scotland was found to be most 

 suited to form 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 S(!ots belonged to the Neo- 

 lithic period of culture. Part I. deals with the deliberate 

 iuterference by man with animal life under the headings
