The writer was the third member of the Army Board. Born in Cuba
during the ten years" war, while still a child, my father
having been killed in battle against the Spanish, I was taken
to the United States and educated in the public schools and in
the College of the City of New York, graduating from the
College of Physicians and Surgeons in 1892. At the breaking out
of the war I was assistant bacteriologist in the New York
Health Department. The subject of yellow fever research was my
chief object from the outset, and, at the time the board was
appointed, I was in charge of the laboratory of the Division of
Cuba, in Havana.

On the morning of Christmas day, 1821, Faraday called his wife
into his laboratory to witness, for the first time in the
history of man, the revolution of a magnet around an electric
current. The foundations of electromagnetics were laid and the
edifice was built by Faraday upon this foundation in the
fourteen succeeding years. In those years and from those
labors, the electro-motor, the motor generator, the electrical
utilization of water power, the electric car, electric
lighting, the telephone and telegraph, in short all that is
comprised in modern electrical machinery came actually or
potentially into being. The little rotating magnet which
Faraday showed his wife was, in fact, the first electric motor.
