100 Bibliographical Notices. 



plants" to the latest revelations of the modern microscope. Wide 

 though this survev is, and admirable in its treatment, we yet feel 

 some surprise at the omission of any reference to the views of 

 Mr. Sedgwick on the subject of the cell-theory. 



The section on the Foraminifera by Mr. J. J. Lister is a monu- 

 ment of thoroughness. Embracing all the results, of any consequence, 

 of the work of others in this field, he has added much that is new, 

 presenting his facts with great clearness and force. We have only 

 one small omission to notice, and that is the absence of Sherborn's 

 'Bibliography of the Foraminifera' and his 'Index to the Genera 

 and Species of the Foraminifera ' from the list of " Literature 

 referred to." 



Scarcely less valuable is the section by Prof. Hickson on the 

 Infusoria (Corticata Heterokaryota). It is refreshing to remark in 

 reading this section, and also other sections of this treatise, a more 

 philosophical method of treatment than is to be found in any other 

 similar work. 



Eut the bulk of this book is devoted to what may justly be called 

 the masterly treatise on the Sporozoa by Prof. E. A. Minchin. 

 Remembering the part that many of these lowly organisms play as 

 parasites and the ravages they commit, there can be no doubt but 

 that the decision to make this section as complete as possible will be 

 commended. To the medical man, as well as to the biologist, it will 

 prove a source of great help, inasmuch as the author's account of 

 the life-history of the malaria parasite is the first which has 

 appeared in a general work on natural history in this country. 

 Besides this, however, there is much else in the section that is now, 

 for the first time, placed before the student in a readily accessible 

 form, and a very great deal that is the result of laborious research 

 on the part of the author himself. 



Like the earlier parts, the tone of this volume is seriously dignified 

 and the matter of the very best of its kind possible. There is a 

 wealth of illustrations, all of which are excellent and many are 

 new. We await with impatience the appearance of the first 

 fascicle. 



We regret to announce the death of Dr. William Francis, for 

 many years one of the Editors of this Magazine, which took place 

 on the 19th January. A short notice will appear next month.
