Bibliographical Notices. 127 



The volume on the Protozoa is the first of the two devoted to 

 this group. The second volume, or second " Fascicle," has already 

 been reviewed in these pages. With the issue of the present 

 volume students have the most complete account of the Protozoa 

 yet published ; and this fact now assumes considerable importance, 

 for during recent years the Protozoa have acquired a quite un- 

 expected significance, owing to the discovery of the part they play 

 in the history of man's well-being. 



The first part of the Editor's Introduction to the Series occupies 

 the opening pages of the volume now before us — the continuation 

 thereof appearing in the second fascicle, — and this will be read with 

 profit and enjoyment by all who are interested in the problems of 

 the origin of life and the relation between animals and plants. 

 These are still much discussed themes, but there is probably no 

 other living writer who could have summarized the present state of 

 our knowledge of this aspect of these lowly organisms in the same 

 masterly fashion. 



The study of the Protozoa is one which presents unusual diffi- 

 culties, and, moreover, the field is so vast that nowadays no single 

 worker can hope to master its intricate mazes. The fact that the 

 present fascicle is the work of no less than six authors — not in- 

 cluding the Editor — is perhaps the best proof of this. 



The section on the Hgemofiagellates and allied forms is, from its 

 relation to disease, one of the most important in the book ; and this 

 has been written by Dr. H. M. Woodcock, Assistant to the Professor 

 of Protozoology in the University of London. It forms an admirable 

 summary of our knowledge of these organisms, based on a very 

 practical first-hand acquaintance therewith. 



Though the Mycetozoa are very properly included in these pages, 

 there are many authorities who still insist on claiming them as 

 plants, and to this subkingdom, indeed, they are officially relegated 

 in the British Museum ! 



These volumes, like those of the series which have already 

 appeared, are admirably illustrated, every figure having a definite 

 lesson, which is by no means the case with most other treatises.

The name of Nicholas Frank Dobre'e was well known to British 

 entomologists, and we are glad to welcome this carefully prepared 

 Catalogue of his valuable collection of Pahearctic Noctuse, now in 

 the Hull Museum. The work commences with a short memoir and 

 an account of the collection and of Mr. Dobre'e's work ; his portrait 

 forms a frontispiece. In the Catalogue the history of each specimen 

 is fully recorded and every aberration or variety is described. In 

 the Appendices we find lists of Mr. Dobree's correspondents j a list
