BOOK REVIEWS Organic Syntheses. \-oluine 35. T . L. CAIRSS, Editor-inChief. John IYiley aiid Sons, Inc., 410 Fourth Avenue, Xew York 16, S . 1’. 1955. vi 122 pp. 15.5 X 23.5 cin. Price, $2.75. I-olume 35 of “Organic Syntheses” contains directions for t h e preparation of thirty-six organic compounds. T h e editing a n d presentation of t h e experiments in tliis latest addition t o t h e annual series a r e rer>- good a n d follow t h e pattern of previous volumes. LVithout d o u b t this is a work of considerable value t o t h e practicing organic chemist. rictually, one wonders how t h e editors manage so well t o meet the requirements of a new volunie each year without including m a n y over-specialized preparntions which would seriously weaken t h e series.
edition of “Diffusion in Metallen.” T h e quality a n d quant i t y of experimental d a t a has increased tremendously, d u e in large p a r t t o t h e widespread availxbility of artificially produced radioisotopes; notable progress i n understanding the mechanism of t h e diffusion process has resulted from both t h e theoretical a n d esperimental a t t a c k s ; a s t a r t has been made toward putting t h e problem of “structure-sensttlve” diffusion on n rational a n d quantitati\-e b surprising, therefore, t o tind this secoiid thorouglily re\-iscd and gre2itly espanded. T h e first third of the book, denling largcl!. with cllicrimeiital aspects, is inairily ail updating of ciirrehponding chapters in tlie first edition.
