...important eastbound convoys were the prey of submarine wolf packs, ranging the Atlantic between the U.S. and Eng land. In midocean, beyond the zone of air protection from Britain, the convoys suffered (losses: unannounced). When the battle moved within range of the four-motored Liberators and Sunderlands of Britain's Coastal Command, the Nazi wolves paid: five were probably sunk, many others were damaged...
Carnivorous plants spread from South Carolina to Ceylon. There are about 450 species. Their methods of capturing their prey (ostensibly nothing larger than insects) are in some measure common to all. But Professor Lloyd breaks down their "trapping mechanisms" into six categories -pitfalls, lobster pots, snares, flypaper or birdlime traps, steel traps and mousetraps. The plants lure their victims by odors, the secretion of nectar and mucilage, the display of bright colors. With few exceptions, the plants have means of digesting their prey.* Enzymes and acids are excreted, and when these are accumulated together with the prey, something like...
...lobes. The glands [with which the surface of the leaf lobes are covered] then secrete a digestive fluid and in a few days the insect body disintegrates and the products are absorbed. In the course of ten days the lobes open again, and are ready to catch other prey. This may be repeated two or three times before the leaf reaches its complete maturity, when it dies...

...more successfully than sulfa drugs do. Unlike sulfa drugs, penicillin's effects are not inhibited by pus and other materials formed in infected wounds. Used in low concentrations in the blood stream, penicillin's action is bacteriostatic, i.e., it prevents bacteria from multiplying and renders them easy prey for white blood corpuscles. Penicillin solutions strong enough to kill bacteria may safely be injected under the skin near a wound or used as a dressing...
