...Smith, 36, is a Johns Hopkins graduate, small, shy and darkly attractive. When newshawks besieged her day after the announcement of her discovery, she made Dr. McCordock answer most of their questions. He carefully explained that she had not, as the Press first leaped to announce, isolated the virus of the disease. She had simply demonstrated the presence of a virus. To establish that it was the virus of encephalitis, it would have to be isolated and passed through a series of animals. If these developed the disease's symptoms, then would come the work of producing a serum...
Some of the cells were abnormally large. By means of stains she discovered inside these oversized cells small bodies called intranuclear inclusions. These are the only visible evidence of the presence of a disease-causing virus, so subtle that it passes readily through a porcelain filter...

But the name and effects of the disease are almost all that is known about it.

First they proved on guinea pigs, rabbits and themselves that the placental extracts were not poisonous and caused no sex derangements. Then on guinea pigs, rabbits and monkeys they demonstrated that the extract neutralized diphtheria toxin and infantile paralysis virus, and caused scarlet fever rashes to blanch.

Most discussed recent proponent of the germ theory has been Dr. William Ewart Gye of London, who indicated a virus. Last year Dr. Edward Watts Saunders of Cornell suggested a streptococcus...
