THE action of the esters of some of the halogenated fatty acids in the vapor phase upon insects was tested. From the standpoints of toxicity to insects, availability, cost, and freedom from fire hazard, methyl, isopropyl, and ethyl monochloroacetates appear to be the most promising of the lower alky

β¦ Synopsis
The Chemical Warfare School of Applied Chemistry at The Massachusetts Institute of Technology is described by CAPT. M. E. BARKER (Chemical Warfare, 1928, 14, 372-373).
This school is a graduate course covering two full calendar years. The preparatory subjects or professional prerequisites usually include calculus, chemical principles, and industrial stoichiometry.
The required subjects include chemical engineering, differential equations, industrial organization, industrial chemistry, organic chemistry laboratory, advanced inorganic chemistry, powders and explosives, chemical engineering practice, and a research and thesis topic.
The chemical engineering practice includes three periods of eight weeks each, spent, respectively, in heavy chemical manufacturing plants in Boston, the paper, pulp, and cellulose factories at Bangor, Maine, and the steel mills and by-product coke ovens at Buffalo, New York. The 8 or IO electives, which must also be completed, are usually related to the subject of the thesis, and are selected from groups in organic chemistry, chemical engineering, and mechanical engineering.
