The subject of this notice was born in Charleston, N. H., Aug. 20, 1830, and at an early age was graduated from one of the academic institutions of his native State. Soon afterward he began the study of medicine at Springfield, Vt., and in the spring of 1857 was graduated with honor from the College of Physicians and Surgeons of New York City. Such had been his close application to his books, and his habit of observation was so thorough and concentrated, that, immediately upon leaving college, he was appointed Attendant Physician at the New Jersey State Lunatic Asylum, located at Trenton, and which position he held until the summer of 1870.

Dr. Carriel at an early period in his life became deeply interested in the treatment of insanity and determined to make it a specialty. With this end in view he spent nearly the whole year of 1860 among the insane hospitals of England, Ireland, Scotland, and France. In July, 1870, he entered upon the duties of his resent position. At that time this was the only asylum for the insane in the State, and it contained 450 patients. It has now under its fostering care 930 patients, while there are scattered throughout the State four other institutions for the treatment of this peculiar and rapidly increasing malady.

While a resident of New Jersey Dr. Carriel was married, May 6, 1862, to Miss Mary K. Buttolph, daughter of the then Superintendent of the New Jersey State Insane Asylum. Mrs. Carriel died in 1873, leaving three sons: The eldest, Harry B., is practicing medicine in Chicago, Ill.; Horace A. runs a cattle ranch in Texas; and Frank B. is a student at Jacksonville. The Doctor contracted a second marriage in 1875, with Miss Mary L. Turner, daughter of Professor J. B. turner, of Jacksonville. Both he and Mrs. Carriel are members of the Presbyterian Church.

In his reading and researches Dr. Carriel reports that among the insane of this State the sexes are about equally divided. Educated people are less liable to insanity than are the uneducated. The fact that insanity is on the increase is attributed largely to the foreign population, which comprises nineteen percent of the whole, while among the insane forty-five per cent are of foreign birth. Of the large number of patients at Jacksonville not over 100 are thought to be curable. Dr. Carriel, who has no superior in the treatment of this disease, estimates that recent cases of insanity are largely curable. If taken in hand within three months from its development, seventy per cent are curable. If allowed to run six months, the per cent, would be reduced to fifty. If allowed to run twelve months, not to exceed twenty-five percent could be cured, and if two years intervene the case may be classed as wholly incurable.
