CARMICHAEL, a distinguished physician, only son of Thomas
Carmichael, Esq., representative of the Carmichaels of Balmadie, and his
wife Margaret, eldest daughter and heiress of James Smyth, Esq. of
Athenry, was born in Fifeshire in 1741. In compliance with the
testamentary injunctions of his maternal grandfather, he assumed the
name and arms of Smyth, in addition to his own. After studying for six
years at the university of Edinburgh, he graduated there in 1764, when
he wrote a dissertation De Paralysi, and introduced into it a short
history of Medical Electricity in its application to the cure of this
disease. He subsequently, for professional improvement, visited France,
Italy, and Holland, and in 1768 settled in London. His first public
appointment was physician to the Middlesex hospital; he had also
considerable private practice. His attention having been particularly
directed to the prevention of contagion in cases of fever, he had
recourse to the effect of nitric acid gas, the preventive power of which
he fully established. His experiments made by order of government on
board of the Spanish prison ship at Winchester, where a pestilential
fever prevailed, were deemed satisfactory, and in 1802, parliament, in
requital of his services, voted him a reward of £5,000. His claim to the
original merit of this valuable discovery was disputed by Dr. James
Johnstone of Kidderminster, for his father, and by M. Chaptal of France,
on behalf of Guyton-Morveau, and he was involved in a severe polemical
dispute in consequence with several of the profession. Soon after, for
his health he went to the south of France, and subsequently, retiring
from professional pursuits, went to live at Sunbury. He was a fellow of
the Royal College of Physicians, London, also a fellow of the royal
Society, London, and physician extraordinary to the king, George III. He
died 18th June 1821. He had married in 1775, Mary, only child and
heiress of Thomas Holyland, Esq. of Bromley, Kent, and had by her eight
sons and two daughters. His eldest son, General Sir James Carmichael
Smyth, was created a baronet of the United Kingdom in 1821. His eldest
daughter married Dr. Alexander Monro, professor of anatomy in the
university of Edinburgh. (See CARMICHAEL of Balmadie.)
