But it does not appear that Boerhaave ever tried to get rid of the eruption of smallpox by means of drugs. In the chapter of his Aphorisms, “De Variolis” (§ 1392) he says that he imagines a specific might be found, in the class of antidotes, to correct and destroy the variolous virus, indicating antimony and mercury as likely agents for the purpose owing to certain physical properties of the medicinal preparations of them. Ruston (An Essay on Inoculation, 3rd ed. 1768) says that Boerhaave, who died in 1738, “never practised it himself; nor seems to have understood the manner in which these medicines operate to produce their salutary effects.” However they were known as the Boerhaavian antidotes to smallpox, and were used in Rhode Island, it is said with great success and as a secret. Ruston used them in England, and discovered by an analysis that Sutton’s secret powders were the same. They seem also to have been used by Cheyne to prevent the development of smallpox in persons who had been exposed to contagion and had presumably taken the contagion. Frewen, in 1759, published a pamphlet to show the improbability of antimony and mercury having any such action, and the fallacy of the claims made for their success.
[927] The Duchess gave the following account of her own case (Gent. Magaz. Nov. 1765, p. 495, sent by Gatti to a friend in London): “On the 12th of March, 1763, I was inoculated for the smallpox, and about four or five days afterwards a redness appeared round the orifice, which Mons. Gatti called an inflammation, and assured me was a sign that the smallpox had taken effect: these were the very terms he used. The redness or inflammation increased every day, and about the seventh or eighth day, the wound began to suppurate. There appeared also about the wound six small risings, or pimples, which successively suppurated and disappeared the next day. Mons. Gatti, upon their appearance, again assured me that the smallpox had taken effect. In the afternoon of the eleventh or twelfth day of my inoculation I felt a general uneasiness and emotion, a pain in my head and my back, and about my heart, in consequence of which I went to bed sooner than ordinary. I slept well, however, and rose without any disorder in the morning. These symptoms Mons. Gatti assured me were the forerunners of the eruption. The next day a pretty large rising or pimple appeared in my forehead, turned white, and then died away, leaving a mark which continued many days.
“The wound in my arm continued to suppurate seven or eight days, and Mons. Gatti now assured me that I had nothing to fear from the smallpox; and upon this assurance I relied without the least doubt, and continued in perfect confidence of my security till the natural smallpox appeared. I continued very well during the whole time of my inoculation, except one day, as mentioned above, and I went out every day.

[928] Gibbon’s Autobiography. It was to Dr Maty that Gibbon, in 1759, submitted his French essay on the Study of Literature, having had a fair copy of it transcribed by one of the French prisoners at Petersfield. Of Maty he says: “His reputation was justly founded on the eighteen volumes of the Journal Britannique, which he had supported almost alone, with perseverance and success. This humble though useful labour, which had once been dignified by the genius of Bayle and the learning of Le Clerc, was not disgraced by the taste, the knowledge and the judgment of Maty.”
