The Method of Evoi^ution. By H. W. 



Conn, Ph.D., of the Wesleyan University. 



G. P. Putnam's Sons, New York and L,on- 



don, 1900. 12mo, pp. ix+408, cloth. Price, 



$2. 



Dr. Conn, in "The Method of Evolution," 

 reviews the present attitude of science to- 

 ward the various evolutionary theories. He 

 discusses very fully the theories of heredity 

 inaugurated by Weismann, and calls atten- 

 tion to the great change that they have pro- 

 duced in the view which biologists hold 

 to-day regarding all phenomena connected 

 with evolution and development. The last 

 fifteen years have seen a very profound 

 modification of our ideas concerning theori 

 gin of species, but the facts that have pro- 

 duced the change have hardly been within 

 the reach of the person who is interested in 

 evolution, but cannot follow the discussion 

 in its various ramifications in scientific 

 journals. The purpose of this work is to 

 present to such students a review of the 

 subject of evolution as it stands to-day. 

 The reader of this work will not require a 

 technical knowledge of biological data in 

 order to comprehend the matter presented. 



A First Book in Organic Evoi^ution. By 

 D. Kerfoot Shute, A.B., M.D. The Open 

 Court Publishing Company, Chicago. 

 12mo, pp. 285, cloth. Illustrated. Price, 

 $2. 



Dr. Shute prepared this work chiefly for 

 the use of students in the Medical Depart- 

 ment of the Columbian University, intend- 

 ing it to serve only as an introduction to 

 the study of the Development Theory. No 

 attempt is made to prove the theory of evo- 

 lution, for this is assumed. Major J. W. 

 Powell says of this work: "It is a presenta- 

 tion of the s^ibject for the general reader, 

 which is masterly, clear and entertaining, 

 A profound subject is thoroughly grasped; 

 a technical subject is made plain ; a complex 

 subject is made simple." 



Chatty Readings in Ei<ementary Sci- 

 ence. Longmans, Green & Co., New 

 York, 1900. 12mo, cloth, in three books. 

 Book I, pp. 124, price, 40 cents; Book II, 

 pp. 132, price, 40 cents; Book III, pp. 186, 

 price, 50 cents. 



These three little books tell of the Animal 

 Kingdom in that interesting, chatty style so 

 fascinating to the child. Prepared for sup- 

 plementary reading, they will be useful both 



in the school-room and the home. The 

 characteristics of each animal mentioned 

 are accurately portrayed and are sufficiently 

 complete to give a good idea of its habits. 

 The three books are copiously illustrated 

 with both black and white and colored pic- 

 tures.
