Experience mull: teach us what degree of heat will be the belt to preferve Fruit without much altering its tafte. E X P E R 1 M. II. July 6. I put into a pot five ounces of Goofe-berries, and having continued the fire till the drop of water would dry away in is feconds, I prefently put it out. The Veiicls being cooled, I found that the Goofe-berries had yielded an ounce and half of liquor pretty thick: I put fome of thefe Goofe-berries to dry in the open Air, and they did dry very well and not corrupt. This Experiment made me the more apt to believe that Sweet-meats might be lo ordered as to keep much of the tafte of the Fruitj and I believe at the fame time one might have a great conveniency to make clear Cakes, becaufe the juyce fit for that purpofe is all kept in this Engine, and may be drawn a great deal fooner than after the ordinary ways.

I took off the fire, and the Veflels being cooled, I found the Goofe-berries very well boiled, foft, and of a good tafte: though the Fermentation had made them hard and unpleafant to the palate. I included at the fame time another pot full with frelh Goofe-berries, to which I added one part of Sugar to five parts of Fruit: I found
