"The disease has hitherto been confined to particular districts; and it has been observed, that where the Cow Pox has prevailed, the Small Pox has been much less frequent, and much less fatal."

"It is a pity that the practice of inoculation has not been more generally adopted; for if it had, many lives might have been saved."

"My greatest ambition has always been to be useful to mankind."
