...allergy to some substance caused the sneezing, Washington doctors scratched her skin some 80 times, rubbed into the scratches hay pollen, flower pollen, pulverized cat fur, dog hair, house dust, food extracts, dozens of substances...
...have enriched its ancient history, traced the outlines of its prehistory. Ireland was not inhabited in Pleistocene times, as Britain and Europe were. Settlers arrived from Britain about 7000 B. C., bringing Stone Age implements some 10,000 of which the Harvardmen found. In geological strata of this period pollen grains of elm, alder, beech and oak and fossil shellfish reveal a warm climate. The Bronze Age began about 1800 B. C., the Iron Age not until 100 A. D. From then until the Anglo-Norman conquests (12th Century) the Irish lived in wicker huts, wooden houses or crannogs-lake...
...plant life involved in the formation of anthracite coal and petrified woods. Never before have botanists been able to secure satisfactory microscopic specimens from these hard rocks. Mr. Darrah has succeeded in making fossil peals of both coal and petrified woods, among them specimens containing the remains of pollen grains more than 200,000,000 years old from a coal deposit in Illinois...
...examined and it was discovered that these super-double flowers were entirely female sterile. They kept on blooming and never went to seed." Because they are "female sterile," the flowers cannot be mated with one another. But not being "male sterile," their strain can be continued by using their pollen to fertilize the double hybrids. The 60-petaled super-double hybrids were shown in Manhattan last week at a special preview for horticulturists, to whom Mr. Burpee recounted the story of his find. The flower has been patented under the name Trapaeolum majus Burpeeii, Mr. Burpee being granted Plant Patent...
Ordinary regal lilies are dehiscent: the pollen-bearing anthers swell, burst open, shower sticky golden dust on the blossoms, marring their virginal immaculacy. GE's lily, which owes its existence to Engineer Chester Newell Moore, is non-dehiscent. Mr. Moore was experimenting with the effects of x-rays on genes and chromosomes (heredity carriers in the germ-plasm). He irradiated 75 bulbs of regal lilies. Nothing noteworthy happened to the first generation, but among the second-generation freaks were two flowers whose anthers shriveled without releasing their pollen. From these two Engineer Moore obtained a true-breeding strain...
