Nitroglycerine Explosives. These are followed by a Supplement on the analysis of nitroglycerine explosives, and by adequate author and subject indexes. The laboratory preparation of nitroglycerine and of the other nitric esters is described, their chemical, physical, and physiological properties are discussed, and plant scale manufacture of the eaplosivc materials and of the finished explosives in cartridges is set forth in detail and illustrated with cuts of apparatus and machinery. The translator has described American practice, pointing out the respects in which it differs from the German. The laboratory sources of the k,nawledge behind the industry are mentioned with references. The reader feels that nitroglyceline explosives have heen produced by research and that the research is still going on. The work is authoritative and will be accepted as standard. It is printed on unglazed and unweighted paper, and is light in the hands-a pkasure to handle. I t augurs well for the Series which it initiates. L. DAVIS TENNEY MASSACHUSETTS INSTITUTE OF TECHNOLOGY
