Abstract
August 26, 1663. It being related by Mr. Oldenburg the secretary, that he had been desired by Monsieur Ludolf, councillor of the duke of Saxe-Gotha, to procure from the society, for a domestic of that prince, who was to be sent into Egypt and Ethiopia, some instructions of inquiries fit to be made in those parts; the society desired Mr. Boyle, Mr. Henshaw, and other members to draw up some queries for that purpose. [Among these was one, “Whether, tho the plague be never so great before, yet on the first day of the river's increase, the plague not only decreaseth, but absolutely ceaseth; not one dying of it after?”]
