...soon developed that Japanese B is transmitted to humans by the bite of a mosquito, Culex tritaeniorhynchus. Only the females are venomous bloodsuckers; the gentle males stick to flower nectar. All well and good, but mosquitoes disappear in winter. Where did they fill up with encephalitis virus in the early summer to pump it into humans? The answer was an animal, no doubt, with seasonal habits-one easily infected with the virus but not made seriously ill or killed by it. That pointed to young animals, which would promptly develop antibodies. The only creatures that fitted these specifications were birds...

...dramatic thrombosis as in the case of President Eisenhower and the individual who sleeps through his heart attack? The answer lies in the gradualness of the process that narrows the coronary artery concerned.

Thus when the final shutdown comes, its original blood flow has already been diverted. In cases like the President's, the collateral circulation has to develop after the attack...

Rust and harvesttime rain cut last year's crop to 309 million bushels, but exports again fell off sharply. Britain withdrew from the International Wheat Agreement, India and France began to grow more of their own grain as a matter of national policy, and Argentina, bouncing back from a year-long drought, stepped up its sales in Latin America. The U.S., burdened with a giant surplus...
