The German government, in cooperation with certain producers of coal-tar products, sponsored and secured an elaborate study of the toxicology and hygiene of motor trucking operations. The items of particular concern were motor fuels, motor lubricants, exhaust gases and condensation products. This study was prompted by the increasing numbers of accidents, such as carbon monoxide asphyxiation in garages, and by the threat that street air may come to contain such a concentration of toxic gases as to constitute a practical hazard. This reprint is primarily made up of technical data based on chemical analyses of fuels, oils and gases; methods of collecting samples under divers conditions, such as in the street, in tunnels and directly from motors; and subjecting small animals to the action of various potentially toxic substances by inhalation and intravenous or intraperitoneal injections. One section is devoted to the methods of control. The authors conclude that carbon
