...educational plants in the U. S. Still intact were the model home economics kitchens, playgrounds, sewing rooms, laboratories, built by the black crude oil that bubbles richly under the East Texas soil. Natural gas heated the individual classroom radiators in the Consolidated School. Whether it had leaked, in its odorless and highly explosive form, from a radiator or whether it had seeped into the unfinished school basement from the soil, no one seemed to know. The superintendent, a lean Texan of 61, sleepless and stunned by the death of his own 17-year-old son Sam, had no explanation...
...inconstancy gave Sir Henry Dale, a big, diligent Englishman, opportunity to pioneer on his own with many a discovery in the chemistry of nerves. One of the subtlest products of nervous reactions is acetylcholine. Sir Henry found this evanescent substance, when isolated from the body, to be a colorless, odorless, crystalline powder. It causes capillaries and small arteries to dilate, thus lowering blood pressure and slowing the action of an overworking heart. It relaxes smooth muscles, thus relieving spasms of the bladder, ureters, uterus, intestines...

Newborn babies breathe once or twice, then breathe no more. . . . In these ways and in many another Death by Asphyxia comes some 50,000 times a year...
...apples, in each piece of food a drop of his chemical (barium carbonate with a slight touch of barium sulphide). Because the Nicholes poison is comparatively slow acting the rats do not die on the premises they infest. Hungry human beings who might eat the poisoned food, which is odorless would not be harmed. They would vomit immediately. Rats cannot vomit...
