this capacity took part in the expedition against Quebec. In subsequent years he used to describe those terrible times, and the torture he endured on account of his helplessness in the midst of so much misery. At the expiration of two years' service he became surgeon to Col. William Douglas' regiment, in July, 1776, and was present through the cam- paign around New York City. He was mustered out with the regiment, on December 29, 1776, and then returned home to resume practice. His health, however, was much impaired, during the next two years, liy what he had under- gone.
He was greatly interested in politics, and was a member of the Lower House of the General Assembly for eighteen sessions (1780-1809). On one occasion he was nominated for the upper house, but was defeated. In his political views he strongly allied himself with the Jeffersonian Democracy, while in his religious belief lie was a Universalist. This attitude in politics and religion placed him at variance with the prevail- ing sentiments of his alma mater, and caused him to speak derogatory words against her.
In tlie zenith of his fame he was prob- ably the most celebrated and popular physician in the state. And rightly, for he strove by buying the latest books on medicine to keep himself well abreast of the times. This helped, also, to make him a famous medical teacher. The celebrated Dr. Lemuel Hopkins of Hart- ford was his first student. His consulta- tion practice was very extensive and carried him over most of the state. For "he was an excellent judge of symptoms and specially skilled in diag- nosis." " In practice he was particularly fond of alkalies and alkaline earths. The famous ' Porter's powder, ' as used by him, was composed of chalk, carbo- nate of ammonia, camphor and charcoal. He used it largely in dyspeptic and other gastric complaints."
He married Sarah Forbes, on April 19, 1764, and had two daughters. These
daughters married two brothers, the younger girl was the mother of Jared P. Kirkland, a physician of Ohio.
His death, which occurred on July 30, 1810, was due to a peculiar accident. As he passed a field of rye on his farm he plucked a head of ripe grain and, on shelling it, threw the kernels into his mouth. Unfortunately, a beard lodged on the uvula, causing inflammatory gan- grene and shortly after, death.
