...used a thin needle, 1¼ inches long, which he passed through a tiny opening in the air-sac end of the egg. After he withdrew the needle, he sealed the hole with paraffin. In three or four days he removed the infected yolks, dried and ground them, diluted them in salt water, produced a remarkably virulent suspension of Rickettsiae, which lost none of its power when passed through ten series of eggs. "The technique," said Bacteriologist Cox, "is very simple, and permits a minimum of contamination." The simplicity of this operation should permit him to make thousands of doses...
...obtained a pituitary substance which did not noticeably affect the thyroid or the sex glands, but which had a marked effect on the mammary glands. It started milk production not only in normal female guinea pigs but also in spayed females and males. In pigeons it thickened the crop sac, which provides a liquid ("pigeon milk") with which pigeons feed their young. Riddle called this new hormone prolactin...
They have measured the crop-sac response of pigeons so closely that it serves as a quantitative test for prolactin in samples sent there by other laboratories. Dr. Bates, who took part in the original discovery of the hormone, has specialized in this "biological assay." Dr. Schooley has worked out a pituitary removal technique for pigeons, going in through the pharynx at the back of the throat, which leaves the back lobe of the gland intact so that almost all the birds survive the operation...
That Elizabeth Madox Roberts was lost in one of these treacherous literary culs-de-sac became painfully clear to most critics three years ago, when she published her obscure, mystical novel, He Sent Forth a Raven. A difficult, humorless book, it had nothing of the earthiness and quiet backwoods simplicity that made her first novel, The Time of Man, a best-seller and a critic's favorite. Instead of plain Kentucky hill folks, its characters were strange, unreal philosophers who explained at great length, in highly polished sentences, that they did not know what it was all about...
...artificial feeding was sometimes necessary. About ten patients suffered bladder paralysis, necessitating the constant and painful use of catheters. Two developed arthritis. Many women had sharp abdominal pains, due to attacks by the germ on the ovaries. Such a diseased ovary, when exposed for surgical treatment, looked "like a sac of pale blue cellophane stuffed with tapioca pudding." The ovaries of a few patients were entirely destroyed and typical menopause symptoms followed. Endocrine disturbances snowed themselves in increased obesity and growth of body hair...
