BOOK REVIEWS Tcddington, who has rontriIx>tpdn grrat, deal to our theoretifit1 nndprstanding of this area of research. The bssie principles necessnr>-for understanding the field are given in thp first part of the book togcther with n dii.nwion of the instruments used. Hew the t r ~ a t ment is somewhat qualitative although more detailed than in the ~ x r ~ l l e nhrid t book by J. D. Roberts. S o nttrmpt u w made to deal with broad-line nuclear magnetic resonance of solids; this mat.erial is treated by the older works of n d r c w and of Sahe and Da.s The second part or thc hook is a ntrve?of the chemical applications of the technique of high resolution S l I R t,hrough 1958. The emphmis is on protan rwonanres, since these are t,heoncs m o ~ useful t and most frequmtly encountpred in the investigation of organic ehemiral sy~tems. Thi~ survey deals brieHy with x wide range of applications t,aken irom the ehemird and physical Iitersture. It swme to he reasonably complete, including in fact a number of unpublished resolti. irom the authors' laboratories. The hihlingraph:should be useful to m y worker in this a r m Naturally, this part of the hank will he the first to become dated as is inevitnhle in such s rapidly moving field. 9 t,n!ly critical survey of this xork remains to he written. Tho present volume was produced by a trans--4tlnntic collaborativ~ effort, working undw diffirulties (some of the work was done a t n Gordon Confer~nee -on the lawn, not in the snnrk bar]. The book will be c x t , r ~ m ~vslunhle Iy tn any one with a serious intweet in NMR spectrosrop.~,especially to student,* and others thinking of doing researrh in the field. To teachers it should provp B useful supplement to the hrider s~-orkof Roherte which iu addressed specificall>-to :I general audience of organic rbemietr. R. P.

Some 20 pages of introdwtion t o types of crystals and t,heir genrrnl properties is followed hy 100 page8 of litpr:,t,ure rwirw of thecurrent knonlrdgp of t h rampounds ~ mentioned in the title. The rurrrnt etatns (up to June, 1957) is then ~ummarieedin terms of ionic and metnllir radii and general concepts as t o the. relxtive validity of "thoride" or "actinklc" hypotheses. The discussion is clear and well translated. If one were to judge from t h ~ literature cited, over 90% of t.he work in this field is done in the United St,ates. This leads t h e reviewer to helieve that the prime purpme of the book wse to revipw "on-Russian work in this area. J. .4. CAMPBELL Harvey .%i'udd College Claremont, California
