248 THE SCOTTISH NATURALIST 



for any notes of errors or omissions. We suggest that any 

 such might be printed later in a supplement on one side of 

 the page only, so that the owner of the complete work may 

 be able, if he so wishes, to cut up these supplementary pages 

 and insert the slips in their proper places. The errors and 

 omissions which we have noticed are so few and unimportant 

 that it would not be just to disparage the whole work 

 by detailing them in this review. In accordance with the 

 authors' printed request we have, however, brought a few 

 mistakes to their private notice, so that they can subsequently 

 make use of our information as they may see fit. 



We understand that " by way of Supplement a Geographi- 

 cal Bibliography, in which the books and articles, as well 

 as the ornithological matter in topographical books, will be 

 arranged under their separate counties, thus affording an 

 index to the work accomplished in the various districts." 

 This "county index, in which will be included not only short 

 titles of the books, but all articles and notes in periodicals 

 by every writer, provided they are of a faunistic nature," 

 should prove as invaluable to the student as the labour of 

 its compilation must have proved gigantic to the authors. 



In the first two parts, now to hand, we have sufficient 

 evidence to show how thoroughly the Authors have ransacked 

 every possible source of information ; we may therefore con- 

 fidently state that when the work is completed it will be one 

 which will be indispensable to every public library and to 

 every individual who is a student of local Ornithology or 

 Bibliography. It may certainly be said that any author with 

 but the slightest claim for inclusion as a writer on ornitho- 

 logy has been mentioned in this work, and that, from a 

 strictly utilitarian point of view, the book might have been 

 curtailed to about one-half without omitting any publication 

 of real ornithological value ; so far from thinking this a 

 fault, we consider it additional testimony to the indefatigable 

 research of Messrs Mullens and Kirke Swann.
