_Collectanea Chymica_: A collection of ten several treatises in chymistry, concerning the liquor Alkehest, the Mercury of Philosophers, and other curiosities worthy the perusal. Written by Eir. Philaletha,[254] Anonymus, J. B. Van-Helmont,[255] Dr. Fr. {126} Antonie,[256] Bernhard Earl of Trevisan,[257] Sir Geo. Ripley,[258] Rog. Bacon,[259] Geo. Starkie,[260] Sir Hugh Platt,[261] and the Tomb of Semiramis. See more in the contents. London, 1684, 8vo. In the advertisements at the ends of these tracts there are upwards of a hundred English tracts, nearly all of the period, and most of them translations. Alchemy looks up since the chemists have found perfectly different substances composed of the same elements and proportions. It is true the chemists cannot yet _transmute_; but they may in time: they poke about most assiduously. It seems, then, that the conviction that alchemy _must_ be impossible was a delusion: but we do not mention it. {127} The astrologers and the alchemists caught it in company in the following, of which I have an unreferenced note. "Mendacem et futilem hominem nominare qui volunt, calendariographum dicunt; at qui sceleratum simul ac impostorem, chimicum.[262] "Crede ratem ventis corpus ne crede chimistis; Est quaevis chimica tutior aura fide."[263] Among the smaller paradoxes of the day is that of the _Times_ newspaper, which always spells it _chymistry_: but so, I believe, do Johnson, Walker, and others. The Arabic work is very likely formed from the Greek: but it may be connected either with [Greek: chemeia] or with [Greek: chumeia]. Lettre d'un gentil-homme de province a une dame de qualite, sur le sujet de la Comete. Paris, 1681, 4to. An opponent of astrology, whom I strongly suspect to have been one of the members of the Academy of Sciences under the name of a country gentleman,[264] writes very good sense on the tremors excited by comets. The Petitioning-Comet: or a brief Chronology of all the famous Comets and their events, that have happened from the birth of Christ to this very day. Together with a modest enquiry into this present comet, London, 1681, 4to. A satirical tract against the cometic prophecy: "This present comet (it's true) is of a menacing aspect, but if the _new parliament_ (for whose convention so many good men pray) continue long to sit, I fear not but the star will lose its virulence and malignancy, or at least its portent be averted from this our nation; which being the humble request to God of all good men, makes me thus entitle it, a Petitioning-Comet." {128} The following anecdote is new to me: "Queen Elizabeth (1558) being then at Richmond, and being disswaded from looking on a comet which did then appear, made answer, _jacta est alea_, the dice are thrown; thereby intimating that the pre-order'd providence of God was above the influence of any star or comet."
