Marshall and Hurst's Practical Zoology. 5 — The fourth edition 

 of this work being called for, the work of revising and editing it has 

 devolved upon Mr. Hurst, to bring the work up to date numerous 

 changes have been made, the most important of which, perhaps, are in 

 the chapter on Amphioxus. 



The work as originally written was intended to give the junior stu- 

 dents of Owens College, Manchester, England, a practical acquaintance 

 with animal morphology, and the present revised edition will be found 

 a useful laboratory text book for any one who wishes to acquire an 

 insight into the leading facts of Animal structure, and a technical 

 knowledge of the principal methods of research. 



The illustrations are intentionally few, as it is expected that the stu- 

 dent will make drawings from his own dissections. These are, however, 

 of excellent quality. 



"Works of this class are of utility in the laboratory, but they do not 

 take the place of general text books as guides to the larger problems 

 of zoology. 



Elementary Lessons in Zoology. 6 — In the hands of a com- 

 petent teacher this book will be of value in giving a student a fair start 

 in the study of zoology. It is in reality a Laboratory Manual. Four 

 simple types of animal structure are given to familiarize the student 

 with the meaning of the terms, cell, protoplasm, tissue, </<"; 

 sexuality, etc. Considerable attention is given to insects ; then follow 

 in turn common forms of Crustaceans, Worms, Molluscs and Verte- 

 brates. The study of the animal alive, and in its biological relation to 

 its environment, is made a prominent feature. To this end methods of 

 observation are given with suggestions as to the facts to be ascertained. 

 In this way the student acquires a practical knowledge of the life 

 histories of the animals studied. 



An appendix contains directions for the preparation of material for 



The illustrations are intended as guides to identification, and in a 

 very general way, they answer the purpose.
