Letterpress copybook with approximately 925 manuscript letters, on 500 numbered leaves, sent to patients' families and physicians
from the superintendent and physicians at Hudson River State Hospital in Poughkeepsie, Dutchess County, New York. The majority
of the letters are signed by Dr. J.M. Cleaveland, Superintendent, concerning the mental and physical condition of his patients
over a twelve-month period in 1882 and 1883. However, the actual author of the letters (and the individual in whose hand they
are written) is Dr. Abner O. Kellogg, his assistant, who signs a few of the letters himself at intervals when Cleavland is
absent. Dr. Kellogg was a noted physician and specialist in the field of women's health. His letters were written to patients'
parents, spouses, physicians, or sponsors.
