Los Angeles cabinet-maker Edward Stewart may be a modern Dr. Frankenstein. In 1959, he cla

ims, he restored a dead friend to life with a simple technique. He opened the dead man's chest, rubbed his heart with a "secret, life-giving" plant juice, then stimulated the heartbeat with 110 volts of electricity. The friend, says Stewart, has. been living in Hawaii ever since.

Stewart also claims his revivification technique works on the small animals he suffocates in jars in his garage. It takes three hours to revive a dead mouse, he reports, and five hours for a small dog. "Some times, "he adds , "I buy those little chicken hearts in the super-market, and I make them beat again using my plant juice before I cook them for dinner."

According to Stewart, he discovered the plant juice one day while cutting hedges around his former home in Hawaii. Juice from one of the plants splattered onto his wrist, he says, and he suddenly noticed the skin begin to twitch. Nonetheless, he adds, he can't reveal the name of the plant. "When the juice is zapped with electricity, "he says, "it gives off a deadly gas."

To promote his idea, Stewart has spent the past decade sending his papers to the University of California, the Army, and a number of government agencies. One scientist who evaluated the concept was Lynn Eldridge, of the Jerry Lewis Neuromuscular Research Center, in Los Angeles. She says Stewart may not be joking. "The extracts from plant like belladonna are used to supply nutrients to human organs, which must be kept alive while traveling to a transplant. So Stewart might cut the heart out of a mouse and keep it alive with plant juice. But this effect is short-lived, and the organ must be placed into a healthy body or it dies. It's impossible to place a live organ in a dead body and expect it to revive every other organ in that body. I think Stewart has observed a basic scientific phenomenon, but his interpretation is crazy."
