And if I shall see that this treatise of distillation passes with acceptance among the artists of this nation, I shall hereafter gratify them for their good will with two other parts of chemistry, viz. sublimation and calcination. And I hope this will be occasion to set the more expert artist on work, for the communicating their experiences to the world. One thing (courteous reader) let me desire you to take notice of, viz. whereas every process is set down plain, yet all of them must be proceeded in secundum artem alchymistae (which art indeed is obtained by experience) and therefore many that work according to the bare process effect not what they intend, and the reason is this, because there was some art of the alchemist wanting. To conclude, if you know more or better things than these, be candid and impart them (considering that I wrote these for them that know them not); if not, accept the endeavors of your friend, John French.
