They discounted U. S. attempts to justify the use of gas and herbicides in Vietnam on the grounds that they are not lethal...
...Biological weapons have not yet been perfected. Viruses contain small molecules which can be unpredictably changed by enzymes in the human body. This makes it impossible to measure a weapon's degree of toxicity. We must assume that all are potentially lethal," said Matthew S. Meselson, professor of Biology and a member of the group, at a press conference here yesterday...
...refinements-that G.I.s faced in the island-hopping battles of World War II. It is an interminable blindman's buff that has squads and platoons snaking stealthily along tangled jungle paths, ever fearful of snipers' bullets, ever watchful for the trip wire that might set off a lethal "Bouncing Betty" mine or drive poison-tipped stakes into a man's chest. The big set-piece battles-Chu Lai and Plei Me, Chu Pong and la Drang-were the exceptions, and even they
...Lethal Vagina. A major controversy in female physiology has concerned the source of the all-important vaginal lubricant. Some authorities have traced it to the uterine cervix; others, to the Bartholin glands flanking the vagina. In fact, says Dr. Masters, the normal cervix secretes nothing of any importance; the Bartholin glands secrete only a minute quantity of lubricant. According to Dr. Masters, the vaginal walls themselves supply nearly all the vaginal lubricant. How they do so is unclear, since there are no glands in the vaginal walls, and this is a subject of continuing study...
...Sims suggested in 1888, says Dr. Masters, the vagina seems to be a functioning as well as a functional organ. In some cases, at least, its biochemical activity may completely defeat nature's purpose. In 39 patients, Dr. Masters has found a vaginal secretion that was absolutely lethal for spermatozoa; three more patients had an equally deadly cervical secretion. The chemical nature of these substances is not yet known, but since some of them kill all accessible sperm within ten seconds, Dr. Masters says, "research in this direction is important both from a conceptive and a contraceptive point...
