"In the year 1777 ... I saw a case of the Diabetes Mellitus in a weaver at Edinburgh. He had been at least four months in the Royal Infirmary without having derived any advantage, and was chiedy under the care of the late Dr. Hope, Professor of Botany. When the patient was discharged, a Mr. Johnstone, then a Student of Physic, and myself, detained him a few days, and paid his expenses, in order to bleed him, and obtain some of his urine, so as to ascertain the appearances and spontaneous changes. I well remember that the blood and urine exhibited the appearances discribed by Dr. Dobson; but the papers, and a portion of the saccharine extract which I carried with me abroad, were lost in the hurricane at Barbados in 1789."
