FIRST EDITION, CONTAINING ONE OF BOYLE'S EARLIEST PUBLISHED WORKS. Boyle's anonymously written twenty-page essay is among the nine addresses included in this rare anthology. Boyle was introduced to Samuel Hartlib by Lady Ranelagh, and he seems to have turned his interest to medicine and such practical matters as agriculture. Medicine led Boyle to chemistry, at first for the preparation of drugs, and he quickly became a skillful chemical experimenter and an original chemical thinker. This essay reflects his modern attitude when he urges physicians to divulge their secrets for the well-being of the publick: "...I find some Physitians objecting, that having laid out much of their mony, and more of their time, in the search of such and such a secret, that discovery is now become either their Fortune, or their Subsistence, and by consequent the divulging it to others would prove destructive to themselves. In this case I must ingeniously confess that all I can require is, that they deny not those that want it the benefit of the Composition, whilst that bewrays not the receipt, and refuse not to impart the Secret it self to those that need it, upon reasonable terms: for they that will not assent to this, must flie for shelter to some other excuse."
The other works include: "Whether the Urim of Thummim were given in the Mount"; "Sir George Ripley's Epistle to King Edward unfolded"; "Gabriel Plats Caveat for Alchymists"; "A Conference concerning the Phylosphers Stone"; "Whether or no each Several Disease hath a Particular Remedy"; William De Rand's "A short and easie Method of Chirurgery"; Gerard Malynes' "Philosophy about the essence and existence of metals"; and "The New Postilions, pretended Propphetical Prognostication, of what shall happen to Physitians, Chyrurgeons, Apothecaries, Alchymists, and Miners."
