[Illustration: WALTER REED.

In the year 1900, Major Walter Reed, a surgeon in the United States
Army, demonstrated, by experiments conducted in Cuba, that a mosquito
of a single species, Stegomyia fasciata, which has sucked the blood of
a yellow-fever patient may transmit the disease by biting another
person, but not until about twelve days have elapsed. He also proved,
as described in Volume I, Part II, that the malady is not contagious.
"With the exception of the discovery of anaesthesia," said Professor
Welch, of Johns Hopkins University, "Dr. Reed's researches are the
most valuable contributions to science ever made in this country."
General Leonard Wood declared the discovery to be the "greatest
medical work of modern times," which, in the words of President
Roosevelt, "renders mankind his debtor." Major Reed died November 23,
1902.]
