Many a patient who takes penicillin in lozenges or sprays shows a marked discoloration of the tongue; most U.S. doctors have blamed the disease rather than the cure. Following up the work of doctors in Britain and India, Dr. Samuel A. Wolfson of Los Angeles came to a different conclusion: he showed that penicillin itself causes blackening of the tongue, may even cause the growth of black "hairs" up to half an inch long. Fortunately, the disorder clears up automatically after penicillin treatment is ended...

...week's Science magazine, Dr. Alber Wolfson of Northwestern University advances his explanation: that they are led astray by the earth's fickle geology. According to a fairly well established theory, says Dr. Wolfson, the continents were once bunched together in two main masses: "Laurasia" (North America and Eurasia) and "Gondwana" (South America, Africa, Antarctica, Australia), which were separated only by shallow seas (see map). During the Cretaceous period, 60 million years ago, both masses broke up and drifted slowly apart, their light granitic rocks floating on the heavy, plastic basalt that underlies both the oceans...
...time this movement got under way, birds had already evolved into modern types. Dr. Wolfson thinks that some of them had learned to make comparatively short seasonal migrations between feeding and nesting places, that generation after generation, for millions of years, they stuck to the same routes. New oceans appeared and widened under their beating wings. New mountains reared up. The climate changed as glaciers crept forward, then melted. The birds, more steadfast than the earth, kept to their ancient flight plan, though their journeys became much longer than at first and twice as long as need...
