...surface of the distillate and a cold condensing surface, molecules can be separated by weight. "Dr. K. Hickman," said Dr. K. Hickman last week, ''began experiments in high-vacuum distillation in 1927. In 1931 he constructed the continuous molecular still and was able to separate from cod-liver oil a golden waxy concentrate which showed high potency of vitamins A and D. Up to this time, molecular distillation had been a scientific curiosity. It represented the ultimate in the application of vacuum...

...temperature increased, the distillation rate of each vitamin changed and each had its characteristic peak. By this means he established that different fishes manufacture different kinds of Vitamin D. Vitamin D obtained from bluefin tuna did not resemble, in distillation behavior, the vitamin from white sea bass. Cod-liver oil was found to contain two major Vitamin Ds and some minor ones, making at least four and possibly five in all. When the new stills are completed it is hoped that these will be isolated and identified...

...like the organs of healthy young humans, are composed of cuboidal cells. These cells are vulnerable to alcohol, chloroform, uranium nitrate and other poisons. If the poisoning is slight, the destroyed cuboidal cells are promptly replaced. But if the poisoning is serious, peculiar flat cells repair the damage to liver and kidneys. Those flat cells withstand great amounts of intoxication, and possibly explain why mature men and women carry their liquor better than juveniles. "The mechanism which prevents poisons from injuring this type of cells is entirely unknown," said Dr. MacNider...

...livers of senile men and women, continued Dr. MacNider, and the organs of senile dogs, even those that are known never to have been touched by poison or disease, are composed almost entirely of flat cells. Those senile flat cells are identical in appearance with the flat liver and kidney cells of young dogs which Dr. MacNider experimentally poisoned...
