Proteins a n d iiinirio Acids in S u f i i t i o n . MELVILLESAHYUS,Editol.. 566 ]Jp. Xeiy Tork: Reinhold Publishing Corporation, 1948. Price : $7.50. I?or several years t h e concentration of nutritional interest, so loiig centered o n vitamiris, has been veering sway toward proteins a n d amino acids, t h e break being conveniently bridged in p a r t by s a c h interrelationships as those of niacin and t r y p t o p h a n in t h e etiology of pellagra. There is, inderd, danger t h a t t h e enthusiasts who recently sought t o cure all t h e world's ills by vitamin dosage, mxy noly a t t e m p t a similar t o u r de force, more expensivelp! with aniino acids. I n a n y case there is obvious need of a scholarly review of t h e whole subject of proteitis and amino acids in nutrition, arid t h a t is what, Sahyun a n d his seventeen collahorittors have a t t e m p t e d t o provide in the present, book. I n t h e introduction, lr. I3.Lewis points out t h e changes of opinion about t h e dietary i n t a k e of proteins proper for ni:in. Tlie high recommendations of t h e pioneer Gernian workers gave way in t h e early yexi's of this century t o t h e l o w p r o t e i n school represented b y C h i t t e n d e n ; recently, much pri'ssure seems t o be developing t o complete t h e cycle and t o return t o levels which ivoultl have pleased Carl Voit arid J u s t u s von Liebig. But t h e present book, though shon-ing m a n y imprints of t h e ncw vogue, is largely a sober summary of evidence on protein utilizatioii. deficicncy, arid protein nutrition in clinical states. There is little 011 t h e pure physics or rhemistry of proteins or amino arids nor should one wish t h i s in t h e present contest. T h e several chapters are of u n e y u d interest uiid merit, nor do they together provide an i n t e g x t e d picture or devclop a parlicular theme. While this, as ell as t h e marked variatioiis in style.niayt)e regretred in t h e pres,iiir book,it must be a d m i t t e d that, t h e d a y of t h e rnoiiuniental treiitise, plxiined :tnd executed in det:til hy a single scholar. is o v e r ; t h e modern monograph fly multiple a u t h o r s seems t o ho t h e only solurion to the growth of knowledge ions of a n y single mind. \Te must be grateful for t h e historical chapter (of h \vhic!i, escellerii i n itself, serves t o place t h e broad problems its a developmcrit nl franir for t h e whole hook.
