ing hydraxyl groups in serine and threonine is considered in a paper by D. F. Elliott. This approach is most valuable in that it offers a potentially reliable method for controlling the breakdown of Longer peptide chains, thereby reducing the sequential analysis of larger proteins to problems of the magnitude of insulin. Initial experiments in the formidable task of fractionating the pepsin hydrolyzate of crystdine albumin are outlined by P . Boulanger and G. Biserte. The conlposition and analysis of the highly basic proteins located in cell nuclei, the protamines, and nucleoprotamines are desorihed by K. Felix. E. L. Smith discusses the use of specific peptidases in snalysingpeptide struoture. Two papers discuss the difficult and controvemid problem of collagen structure. W. A. Schroeder describes hi chromstographic experiments on different hydrolyzittes and considers the various theories of collagen structure in the light of his results. Electron microscopy and chemical analysis of various oollagen peptides are disoussed by W. Grassmann. This is a very useful book which summarizes some of the progress in a field of chemistry that is growing very rapidly.

be of use to the one seeking information outside of his own field. In college, the emphasis must be on the technical asspeots of the chemical engineering profession. Because so many of the graduates become more and more engaged in the business aspects of the chemical industry, we must make avdable to our students and introduce to them this "Chemical Business Handhook" so they will know where to turn for informfition as they encounter businem rather than technical problems.
