tlatlon of immunologically competent cells. Bussard discusses 

 difficulties of the clonal selection theory. The general discus- 

 sion which concludes the hook, and in which Edelman, Hood, Auer- 

 bach, Silversteln, Good, bterzl, and several others participated, 

 also revolves largely around the clonal selection - germ line 

 controversy. 



All the discussions held during the symposium are recorded. 

 The Dooks were printed in Czechoslovakia and are well produced 

 and illustrated.

Appleton-Century-Crofts , New York. Papers In development and 



heredity. VI, 231 pp., 97 figs., 30 taos. $ 20.90 



Contents: 1. Experimental embryology of Insects (papers by 

 Seidel and by Seidel, Bock, and Krause); 2. Chemical genetics 

 (papers by Caspari, Beadle and Ephrussi, Tatum and Beadle, 

 Tatum and Haagen-Smlt, and by Poulson); 3. Insect endocrinol- 

 ogy (papers by Kopec, Bodensteln, Wigglesworth, Pukuda, and 

 by Butenandt and Karlson) 



The organization of this book of readings is apparent from the 

 t^ble of contents above. In a 4-page introduction the editor 

 places the papers selected in historical perspective. All papers 

 are preceded by brief biographies of their authors. Those papers 

 which were originally not in English were ably translated by the 

 editor . 



From the point of view of Dibliography the book shows signs of 

 surprising carelessness. Bibliographical data are often cited 

 incorrectly, the original titles are not mentioned, not even the 

 language of the original. In one case (Seidel, Bock, and Krause) 

 only about one third of the original article is included, and 

 though this is certainly Justified, it is nowhere explained. Of 

 one other paper the source is simply omitted. 



The book is well printed and contains the original illustra- 

 tions ,
