The Chemists Key

The Chemists Key to Shut and Open: As the True Doctrine of the Corruption and Generation in Ten Brief Aphorisms Illustrated with most plain and faithful Commentaries out of the Pure Light of Nature: By that Judicious and Industrious ArtistHenry Nollius 1617. This book having worth enough in itself needs not my commendation this Author in his lifetime being an eminent physician and most able Philosopher as the discourse itself can best testify. The translator also wanted not judgment to choose what was best in his kind nor abilities to perform the choice being made. It is I alone that appear here as Menelaus at that feast in the Iliad who came though not invited. I shall not endeavor to excuse myself for I come not empty but will contribute somewhat to the collation. The Author builds on good principles so that his Theory is as true as it is plausible; and I presume he aimed at nothing more leaving all particulars and their application to the industry of his readers. He is sometimes pleased to descend to examples but to such only as are natural and they indeed are good to teach but hard to imitate. We see not all that Nature does.
