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...
...been secreting an acid digestive juice in large quantities from great glands which fill all of its five arms. This fluid acts as an "anesthetic" on the muscles of the oyster, rendering them flabby and useless, after which it becomes an easy matter for the starfish to devour its prey...
