Series I. United States Marine Hospital Patient Records is comprised of 22 volumes which form a nearly complete chronological run from 1843 to 1850. These important and illuminating volumes contain the names, health history, disease symptoms, dates, and nature of treatment provided to the patients Loring attended. All volumes include an index, either by patient name, or, in the case of the 1843 records, by date of hospital entrance. Noted in these pages are descriptions and treatments of such ailments as venereal disease, typhoid, rheumatism, diarrhea, pneumonia, ulcers, cancer, hepatitis, burns, measles, fractures, frostbite, epilepsy, scurvy, leprosy, insanity, intemperance, and gunshot wounds. Of interest are several lists which Loring compiled: a tabulation of the number of cases of each disease (August-November, 1844), and a selection of medicinal recipes, and disease treatments (August-November 1847).
