Abstract
I Had heard by several reports from China and Guinea, but especially from Turkey, of the inoculation (as it is called) of the small-pox; and took an opportuntity, when the late Dr. William Sherrard was consul of the English Nation at Smyrna, to desire the favour of him, it being an operation never practised in these parts, nor by some physicians thought practicable, to inform me of the truth and success of it.
