"The series of books entitled "The machine gun" was begun with the belief that the next best thing to actual knowledge is knowing where to find it. The research summarized within the covers of these volumes has been compiled by the Bureau of Ordinance, Department of the Navy, in order to place in the hands of those rightfully interested in the art of automatic weapon design, the world's recorded progress in this field of endeavor."--Vol. II, p. v.

Luke S. May played a significant role in the development of scientific methods of crime investigation. Although basically self-taught in scientific matters, May spent over a half century practicing scientific crime detection and built a solid reputation among police agencies and attorneys in the Pacific Northwest and Western Canada as a serious and effective scientific investigator. This reputation as "America's Sherlock Holmes" also led to his being consulted on the establishment of the first full service public American crime laboratory at Northwestern University in Chicago, Illinois, and on a laboratory for the Royal Canadian Mounted Police at Regina, Saskatchewan, Canada. When May began, few people, anywhere, used scientific tools to investigate crime. Except for a couple of minimal installations in Europe, there were no crime labs. So to solve his cases – criminal and civil – May improved or invented techniques in every area of forensic science in the era before public crime laboratories. Along the way, he exchanged ideas with many other well-known crime fighting pioneers. American Sherlock: Remembering a Pioneer in Scientific Crime Investigation is the biography of this innovative criminologist, giving a case-based account of his life and honoring him as one of the pioneers of scientific crime detection.

This book has been written for the practicing chemist whose occasional task may be qualitative analysis. It deals with the investigation of things as they are without any limitations to the scope. It emphasizes the identification of materials - inorganic, organic, organized (biological), common, rare, described or not described in the accessible literatur- as they actually occur in nature and industry, or are met in the investigation of mishaps and crime. The description of techniques - macro to submicro - and the practice exercises have been included since the teaching of these arts is rarely a part of academic curricula and it happens with increasing frequency that chemists have to acquire them "on the job". In the systematic procedure given, emphasis is placed upon the investiga tion of minute specimens and upon acute reasoning that continuously weighs all accumulating evi9.ence. The work begins with the consideration of the history of the material under investigation. Especially when specks of all organic substance shall be identified, it should be realized that the discovery of the source - and consequently of the possibilities involve- may be the most valuable clue to an efficient solution of the problem.
