The male frog straddles the female from behind using a branch or leaf to brace himself while he deposits his sperm on the female's back. The female lays her eggs, which are fertilized by the sperm trickling down her backside.

Legally Hot

Through years of spare-time dabbling in such occult sciences as prophecy and mental telepathy, Godfried Bueren, 70, a West German patent attorney, never lost his amateur enthusiasm for astronomy. Finally, he announced, he had learned something that professional astronomers don't know. The sun, asserted Herr Bueren is a hot, hollow sphere, a million miles in diameter; inside its fiery shell floats a cool core, 600,000 miles thick and lush with vegetation. What's more, he had 25,000 marks ($5,945) that said he was correct about the sun.

When Herr Bueren announced his startling theory, most scientists shrugged it off. But the German Astronomical Society accepted the challenge. Said Hamburg Observatory Director Otto Heckmann: the society would like to keep such "silly ideas" from attracting too much attention. Besides, the society needed the money.

Like schoolmasters marking a poor student's test paper Dr. Heckmann and a couple of scientists sharpened their pencils and set to work on Herr Bueren's theory. The sun's corona does blaze at approximately 1,000,000° C., they conceded, but who can believe that the enormous heat is caused, as Herr Bueren also insisted, by cosmic particles striking the sun's outer atmosphere? Why shouldn't the same particles bombard the earth and set it glowing? And did Herr Bueren really believe that sunspots are gaping holes in the sun's shell, opening on to a cool black core where plant life changes heat into chemical energy, thus lowering the temperature? Pure nonsense, said the scientists. As for heat-reducing plants: Dr. Heckmann & Co. pointed out that science knows of no plants that use up all the energy available to them.

A Bueren-picked jury of West German scientists studied the astronomical society's arguments and solemnly announced the the Bueren solar theory had been demolished. His bald pate flushed with anger, the sun-gazing patent attorney refused to pay. "People who want to cash in on the money," he cried, "do not even pay attention to what I have to say."

But Dr. Heckmann and colleagues, having paid attention to the prize offer, sued Bueren in the Osnabruck court. "Science cannot always say what is correct." they argued, "but we have advanced so far as to be able to say what is wrong."

Last week, despite Herr Bueren's dark mutterings that his professorial jury had been intimidated, the court found the sun's core legally hot, ordered him to hand over the 25,000 marks plus a year's interest at 4% and court costs.
