GENERAL REVIEWS. 



A Manual of Zoology. — By the late T. Jefl'ery Parker and William A. Haswell. 

 8 vo., pp. xvi + 550, and 300 figs. London: 1S99, Macmillan <& Co., Ltd. 



This manual forms an admirable introduction to zoology for a class of Students 

 who deserve something more than the modern cram book. Owing to the restrictions 

 of space many "groups of rare occurrence and uncertain relationships" have been 

 wisely omitted and greater space devoted to the more familar forms. In cases of 

 this kind it is always difficult to decide just what to omit and what not, and the 

 authors here seem to have been very happy in their selection. The Brachiopoda 

 might perhaps have received a little more attention. 



We note with pleasure that in the author's opinion laboratory and museum work 

 should be supplemented by work in the field and on the seashore. 



The types are all well chosen and excellently illustrated, particularly the 

 Ccelenterata. Amongst so many modern illustrations it seems a pity to include such 

 figures as fig. 170 (a proglottis of Tccnia), and fig. 81 (Starfish, vertical section of 

 an arm). 



Chapter xi dealing with the MoUusca is well written, and there are some very 

 useful figures illustrating the anatomy of the Cephalopoda. 



We heartily welcome this work, which must prove of great value to junior 

 students.— W.E.C. 



Statistical Methods with special reference to Biological Variation. — By C. B. 

 Davenport. 16 mo., pp. vii+148, and 28 figs. New York: 1S99, John 

 Wiley & Sons. 



This work is intended for those who are interested in the quantitative study of 

 species and of organic variation, and must prove very useful to all biologists engaged 

 in such work. It is clearly and concisely written and remarkably free from errors. 

 The method of using the various tables is carefully explained and fully illustrated. 

 All who are interested in the methods elaborated by Galton and Pearson will welcome 

 Dr. Davenport's handbook. — W.E.C. 



EDITOR'S NOTES. 



It is with feelings of great pleasure that we have to record the receipt of 50 francs 

 from a " French malacologist " towards the deficit on the Journal during 1899. We 

 take this, our only means, of tendering our sincere thanks to the donor for his 

 generous gift and good wishes. 



We cannot refrain from quoting a short paragraph from the letter accompanying 

 the above donation " If," says the writer, " English students of the Mollusca were 

 less shell-collectors and more malacologists your journal would have a balance not 

 a deficit." 



We regret to have to record the deaths of Edgar Leopold Layard on January 

 1st, IQOO, in his seventy-fifth year, and G. Sherriff Tye on February 4th, 1900. 

 A portrait and notice of the latter will appear in our next number. 



We have received from Mr. II. B. Preston his price lists of South African 

 Marine and Land and Freshwater Shells, also Australian L. and F. Shells. Mr. 

 W'alter F. Webb (Albion, N.Y., U.S.A.) sends us a very useful and carefully pre- 

 pared priced check-list of Land Shells of the United States and Canada.
