SOME Berries are also of great Use in Practice; as the Powder of _Ivy-Berries_ given to the Quantity of one Dram in two Parts of _Elder Vinegar_, and One Part of _White-Wine_; the Spirit likewise drawn from _Elder-Berries_ would do the same in a Dose of ℥ iij. or ℥ iv. the Spirit of _Juniper Berries_ given to ℥ i. a Spirit drawn from green _Walnuts_, with _Treacle-Water_, as also from the Seeds of _Carduus_, _Citrons_, &c. had likewise their due Recommendations in powerfully promoting Sweat. BUT I know nothing amongst the _Simples_ that hath so obtained, for Ages together, as the _Oriental Bezoar_, and which still hath so great a Name; yet without having any Inclination to contradict a received Opinion, I have been so confirmed by a Multitude of Trials, that the Truth will speak for it self, which manifestly denies its Virtues to be at all equivalent to its Value: And I have really given it in Powder many times to 40 or 50 Grains, without any manner of Effect; and I dare affirm that the _Bezoar_ with which I made these Trials was genuine. THE Powder also of an _Unicorn_’s Horn, so much cried up for an Antidote, never answered any good Expectations, although I had several Dozes of it given me by a Merchant, on purpose to try its Virtues: But that which would cure Pidgeons, Fowls, Cats and Dogs, from Arsenical Poisons, as the worthy Gentleman assured me that did, had yet no Efficacy against the pestilential Virulence: Yet if it was not controverted to this very Day, whether or no there is such an Animal in Being as an _Unicorn_; and it should moreover be granted that the Horn hath these stupendious Virtues; the Price of it would make it purchaseable only by the Rich; whereas in this dreadful Calamity the Populace were chiefly infected; and therefore cheap and common Medicines should be contrived for them by the Physicians; in the Number of which, first occur the _Troches_ of _Vipers_, given to the Quantity of ℈ iv. in compound _Scordium Water_, or the volatile _Salt_ of _Vipers_ given to ʒ [ss.] in the same Vehicle. A very worthy Person sent us from _New-England_ some Troches made of the Flesh of a _Rattle-Snake_, from which I found more Success amongst the Sick, than those we commonly have here. THE _Powder of Toads_ was likewise prodigiously extolled by every Body; but I found more Success in _Spirits of Hartshorn_, given from ℈ ij. to ʒ i. in _Plague-water_.
