numbers. On the otlier hand the Irish Dipper^ the Irish 

 Coal-Tit, and the Irish Jay, all indigenous forms, appear to 

 have hardly suffered at all. 



A complementary account of the effects of the winter in 

 Co. Down is given by Mr. N. H. Foster in the succeeding 

 number. Here the winter though severe was not excep- 

 tionally so, and extermination was not so noticeable, though 

 there was a great scarcity of Fieldfares ; the Stonechat, 

 Gold-crest and Long-tailed Tit also suffered severely, but 

 not the Grey Wagtail and the Meadow-Pipit. It would be 

 interesting to compare these observations with those brought 

 togetlier at a recent meeting of the B. O. C. (Bull. B. O. C. 

 xxxviii. p. 20). 



A second paper by Mr. Foster deals with the sizes and 

 weights of birds' eggs, the latter of the shells when 

 blown. 



A short article by Mr. Moffat deals with tlie arrival dates 

 of some Irish migrants and discusses the question whether 

 the forward or backward condition of the spring affects these 

 dates ; and Mr. J. P. Burkitt has some field-notes on the 

 nesting and other habits of the Long eared Owl which seem 

 to bring out some novel points. 



A number of short notices by Prof. C. J. Patten and 

 others on occurrences of rare birds at lighthouses and else- 

 where are of some interest, though nothing very novel 

 appears to have transpired during 1917.

The French Ornithological Journal, under the able 

 guidance of M. Menegaux, deals with ornithology, not 

 only in its scientific, but also from a popular and economic 

 aspect. From the latter point of view, we find an article in 

 the present volume by M. Ch. Riviere dealing with the 

 domestication and farming of the Ostrich in Madagascar 

 while the Editor himself puts in a plea for either Kerguelen 

 or the Crozet Islands, both of which groups are in the
