"The first part of Mr. Jourdain's book makes a further addition to the 

 works on Oology now in progress. The letterpress is excellent and gives 

 a fully detailed account of the nest and eggs of each form, with references 

 to plates already published, •— and besides, what is even more important 

 nowadays, a sketch of the breeding range of the different races that have 

 been hitherto described. We may prefer the X2th edition of Linnaeus's 

 'Systema Naturae' to the 1 0th, and may be not inclined to follow the author 

 closely as regards nomenclature, but there can be Only one opinion as to 

 the necessity of an exact knowledge of the various geographical races; 

 and should their nests and eggs prove to differ, this should assuredly be 

 made known. Moreover, any such differences as exist should be reckoned 

 at their full worth in deciding the difficult question of the validity of the 

 various races. . . . Among the many useful points in the work we may 

 notice the lists of^ local British and fbreign names of the birds, the references 

 to other forms the range of which abuts upon the European area, the 

 measurements of the eggs, and the determination of the approximate weight 

 of the shells. It is of course impossible to avoid occasional slips, . . . 

 but the comparative insignificance and infrequency of these inaccuracies only 

 strengthens our opinion of the general accuracy of Mr. Jourdain's work." — 

 Ibis, 190Q, p. 722. 



"So far as we are able to judge from the first part, this work has 

 much to recommend it. The plates are decidedly good, and the letterpress 

 dealing with each species is adequate and affords much reliable information 

 on a wide range of subjects — reference to literature, local and foreign 

 names, breeding range at home and abroad, description of eggs, breeding 

 season, etc. — and bears evidence of considerable research as well as of 

 first hand knowledge on the part of the author. The work is to be 

 completed in about 10 parts, containing some 140 coloured plktes, and 

 promises to be an excellent one in all respects." — Annals of Scottish 

 Natural History, 1906, p. 191. 



"We have now before us the first part of Mr. Jourdain's publication. 

 This is announced to be completed in about ten parts, containing about 

 one hundred and forty coloured plates. Geographical races are fully recognized 

 and described, and the nomenclature recommended by the Fifth International 

 Zoological Congress has been adopted. This instalment contains fourteen 

 beautifully coloured plates and the text is very full and informative." —
