The supplement to a small treatise called Salt-water sweetned shewing the great advantages both by sea and land, of sea-water made fresh. Together with the Honourable Mr. Boyle's letter, and the approbation of the Colledge of Physicians, of the wholsomness of this water. And also the conditions on which the patentees and others concern'd, do intend to contract with such as shall please to deal with them for the use of his invention.

AFter so many forcible and convincing Te∣stimonies in favour of this great Design, I shall make an Addition of the Approbation of His Majesty of Great Brittain; who, after the publication of the first Impression, having seen the convincing Proofs of the healthful Quality of this Water, hath resolv'd to have the same to be made use of in all his Sea-Port Garisons; The which he caused to be published by ex∣press Order, in several Gazetts, and particular∣y in that of Munday, Novemb. 5. 1683.

An ABSTRACT out of the Gazette, Numb. 1676.

HIS Majesty was pleas'd to Command the Ho∣nourable Mr. Boyle to attend Him,* to give His Majesty an Ocular Proof of the Nicety of his way of examining the freshness and saltness of Water, and to apply it to the Sea-Water, prepar'd according to the Patentees Invention; which being done before his Majesty, his Royal Highness, and the Duke of Grafton, several Persons of Quality being also present, it was made apparent, by a certain prepar'd Liquid which Mr. Boyle had brought with him, that a Discovery could be made if there were so much as a thousandth part of Salt in a pro∣pos'd Water: By which Tryal His Majesty, finding that the Prepar'd Sea-Water, for which he has granted his Royal Patent, was at least as free from Salt as the best Waters used in this Town: received such Satisfaction as to the wholsomness of the said Water, that He was pleased to declare his Royal Intentions both to encourage the said Invention, and to have the said Water made use of in his seve∣ral Maritime Garrisons, which Nature has not furnished with wholsom Water.

SIR,

FOR these Four Months past, I kept your Sea-Water (for its better Tryal) Buried in my Ships Hold, where, had it not been extraordinary good, it must infal∣libly have been of no use, and offensive, but I'll assure you it prov'd quite contrary; for yesterday, having several both of Sea and Land Officers on board of me, I made them insensibly taste of your Water, which I pre∣tended to be from a Spring I watered my Ship at, Ten Leagues to the Southward of Sallie; they all affirm'd it to be as good as Tangier Water, the very best counted in the Streights, but when I discovered the Water to be yours, they hardly would give it Credit, and approv'd of it (as really it is, as good as can be drank) which they desi∣red me to let you know.

I am

Your Humble Servant

Novemb. 3. 1683.
