This supplement of "Genetics" contains all the papers read at an inter- 

 national Symposium held in Belo Horizonte, Brazil, in December 1968. Most 

 of the papers deal with two main subjects: chromosome structure and repli- 

 cation, and molecular genetics, both in a variety of experimental material 

 ranging from bacteriophage to mammals. Of the 68 contributors 26 are Bra- 

 zilian scientists. 



The 37 papers are arranged in seven sections as follows: 1. Chromosomal 

 activities during meiosis I (5 papers); 2. Chromosomal activities during meiosis 

 II (7); 3. Nuclear activities during development (6); 4. DNA metabolism 

 during development (7); 5. Genetic redundancy (4); 6. Gene expression 

 during differentiation (6); 7. Nucleic acids in bacteriophage development (2). 

 In his closing remarks H. Swift confines himself to three main areas: chromo- 

 some structure, gene transcription, and gene amplification. 



All papers have English and Portuguese summaries. The volume is amply 

 illustrated and has an alphabetical index.

This Symposium was probably held some time during 1967, but the book 

 does not state when and where. In most of the bibliographies the most recent 

 literature cited is from 1 967. 



The object of the Symposium was to promote collaboration between students 

 of differentiation and of immunology, and the book should arouse the interest 

 of all those who use to think about cytodifferentiation and cell heredity. Why 

 this is so is made clear by Paul Weiss in his lucid introduction entitled "Mo- 

 lecular specificity — link between immunology and differentiation". 



The book contains 16 papers, all by prominent authorities in their respective 

 fields. Several of these of course deal with the immune system and lymphoid 

 cells, but others describe work on protozoa, embryonic cartilage, collagen- 

 synthesizing cells, the embryonic lens, the rat orbital gland, isolated thymus 

 chromatin, and organ-specific tissue extracts. 



The book is well illustrated and well produced, and has an author index.
