The \-oluiiic begins with a paper (15 pages) by Paqunt n n autoxidation of fatty substances, through which t h e rettdcr becomes acquainted with pertinent aspects of peroxide chemistry. Thereafter, follow analytical studies on the radintion formation of peroxides in various organic conipciunds of biological interest, including cumene (11.Durup, 9 pages), amino acids and peptides (S. Okada, 4 pages) and nucleic acids and related compounds ( J . .I.1.. Butler, 3 pages and J . IVeiss, 3 pages). Then papers on t h e presumptive indication of peroxide intermediates, in different biological r.idi.ition reactions including killing of mice ( J . S t . I,. Pltilpiit, et ai.,8 pages), inxtivCition i i f tr:iiisfurming principle i n pneumococci (I- and Sons, Paper and printing are good. There is an Inc., 44@ Fourth Avenue, S e w I'ork 16, S .

tor>-tools for t h e study of high inagiletic fields or the study o f protective materials for the re-entry phase of rockets. The report of this conference presents authoritative a n d , in m a n y instances, quite detailed discussions of t h e equipment used for priiducing tlie high temperature plasmas or of the types o f i i ~ e ; i ~ ~ r e n that ~ e n tcan be made. It is unfortunate t h a t the rel.tsntion of security restrictions in this general field did tmt come early enough t o allow a much broader discussion o f ivurk with plasmas and possible applications. This restrictiun has left a somewhat unbalanced presentation \\-itli sotne topics discussed in great detail and other topics barel>- iiientioned. For those topics which have been :tdequ:itel!- covered t h e reader will find a quite up t o date and comprehensive treatment. Although this work will be of great value t o those active in the plasma field, it will not be very useful t o the casual reader who wishes to gain an over-all view of the activities in this field.
