...Friday the petition of the Plan E Committee, which under the chairmanship of Dean Landis has obtained over 11,000 signatures, was blocked by the Council on trivial technical ground. Mr. McNamara, president of the body, declared that Cambridge "was not going to be turned into a laboratory of guinea pigs for a lot of theorists" and sat down on his political haunches. Even when the ballot law commission certified the petition of Saturday, Mr. McNamara refused to call a special meeting because of an "interfering" ordinance. Mayor Lyons also did his part: to Dean Landis's plea that...
Some were killed and samples of their brain tissue were injected into other healthy mice, which fell sick in two days and died. The virus also worked on monkeys, guinea pigs, rabbits. Typical of eastern equine encephalomyelitis was the two-day incubation period, as well as the violent symptoms which are unique and completely different from those occurring in human beings. As a further check, however, they injected deadly doses of the virus into animals which had been immunized against eastern equine virus. All these remained "perfectly well...
...yardsticks nowadays. Last week a psychologist reduced to statistics some surprising facts about the subtle art of changing people's minds through discussion. Dr. Ray H. Simpson, an instructor in Barnard College, made a study of Those Who Influence and Those Who Are Influenced in Discussions.* His guinea pigs were 185 college girls (Dr. Simpson says his findings would probably have been similar if the subjects had been men.) He determined their opinions on many issues, then formed groups of four students each, with differing opinions, to discuss these questions. After the discussions he again tested them to find...
Last fortnight in The Lancet, Drs. Deanesly & Parkes reported the results of experiments made on the hunch. They anesthetized five immature male guinea pigs, made slits in their skins, pushed a disc-shaped ovarian hormone tablet, weighing from eight to 16 milligrams, into each slit, and stitched up the incision. There was no local reaction but a tight coat of connective tissue began to grow around the tablets. After six months the guinea pigs' male sex organs had atrophied, their rudimentary male mammary glands had become greatly enlarged. The tablets were then removed, dried, weighed. It was found that...
...large female guinea pigs were given implantations of a male hormone and in two months they were definitely on their way toward masculinity. "A single administration," said the scientists, ". . . had produced masculinization which would otherwise have required either frequent injection of androgen [male hormone] or the presence of a transplanted testis." It was discovered that the rate at which the tablets were absorbed ranged from 2% a month for the female hormones to 25% for the male hormones. Best way to insure adequate absorption, said Drs. Deanesly and Parkes, was to use a number of smaller, tablets rather than...
