Season of the Year, as the Spring and Autumn. The Things that hinder it, are, (1.) The Fume of burning Brimstone. (2.) Alkaline Salts, and alkaline Earths. (3.) Closeness of the Veffel. ( 4.) Too great Heat. And, (5.) Extraction of the Air from the Vessel, and Liquor, by the Air-Pump. Fermented We are next shewn how to preserve the Liquors : fermented Liquor; which is a thing known to ved and di... ere every one : and afterwards how to distil it for Rilled. its inflammable Spirit; the Apparatus and Manner whereof does not greatly differ from that of diftilling simple Waters, as described under Process #freenth. And thus at length concludes the History of Fermentation ; wherein We wish ché Author may meet with all the Success he desires, with regard to establishing a folid Doctrine of general Use: for his Notions here seem to be but narrow and limited; whereas the Subject is copious, and diffusive. 43,44. . The forty-third and forty-fourth Processes Vegetable are Exemplifications of the general Doctrine of Matters , Fermentation; the one upon Meal and Malt, fermented. fermented with Water ; the other upon Honey, fermented in the same manner ; to Thew thác they will thus make what the Author calls Winë. THE forty-fifth and forty-sixth Processes are Dirilled performed upon the preceding fermented Matfor spirit, ters, to shew the common Way of making in Aammable Spirits by Distillation ; and that an acid Liquor will rise after the Spirit is come over.

The Processes upon Vegetables conclude with the artificial Manner of putrefying them ; or making them heat, rot, and change to an animal Nature ; so as by Distillation to afford the fame Principles as animal Subjects: whence this last Process leads directly to the Processes upon Animals, which are next to follow.

Process 89-91. are performed upon Cows Milk; to shew, (1.) That when new, it is neither acid nor alkaline, faline or spirituous. (2.) That ic coagulates or curdles with Acids. And (3.) That it turns yellow by being boiled with fixed Alkali. 92-98. PROCESS 92-98. are all performed upon UUrine. rine, to Thew, (1.) That new-made Urine is neither acid nor alkaline. (2.) That by Distillation it affords a ferid nauseous Water, neither acid, alkaline nor vinous. (3.) That the Re'mainder after the Diftillation is neither acid, alkaline,or saponaceous ; but faline and fetid.
