196 THE ZOOLOGIST. 



ordinary dissection. This volume is an incentive to make us 

 really understand all that can be practically learned about a few 

 typical animals, and the thorough mastery of the anatomical 

 and physiological details of these living forms will leaven the 

 whole lump of many zoological conceptions. In fact, as the 

 author states — for one only is now left — "Throughout the book 

 I have borne in mind that the main object of teaching zoology 

 as a part of a liberal education is to familiarise the student not 

 so much with the facts as with the ideas of the science." 



The first thirteen chapters are devoted to the Frog; attention 

 is then paid to some of the most primitive forms of animal life, 

 after which the objects of study are those familiar "zoological 

 models," the Earthworm, the Crayfish, and the Fresh-water 

 Mussel. A few illustrations of the Vertebrata follow, and the 

 concluding chapter is chiefly of an embryological character. In 

 the summary of views respecting the subject of organic evolution 

 we meet with an advice which we do not remember having seen 

 elsewhere: — "As a preliminar} r to the study of Darwin's 'Origin 

 of Species,' the student is recommended to read Romanes' ' Evi- 

 dences of Organic Evolution,' in which the doctrine of Descent 

 is expounded as briefly as is consistent with clearness and 

 accuracy." 



General Index to Miss Ormerod's Reports on Injurious Insects, 



1877 to 1898. 

 Report of Injurious Insects and Common Farm Pests during the 



Year 1899, with Methods of Prevention and Remedy. By 



Eleanor A. Ormerod, F.R. Met. Soc, &c. Simpkin, 



Marshall, Hamilton, Kent & Co., Limited. 

 During a period of twenty-two years Miss Ormerod has 

 issued her Annual Reports on Injurious Insects. The quantity 

 of valuable information, thus one may almost say interred, 

 except to the diligent readers of these reports, is now accessible 

 to all by the publication of an excellent index compiled by Mr. 

 Robert Newstead, himself well acquainted with the subject. 



The twenty-third Report for 1899 commences a second series, 

 and is in no way inferior to its predecessors. Miss Ormerod's
