Heads of Old Garlick 32 fe. were Dryed in a Furnace and Bumt; fromthe Aßies there was hardly any Sah to be garhered.

Thirtj Pounds of Wheat Tlower bumt in a Furnace wirh a litrle Sulphur,and burnt a-new in a Potter’s Oven, gave 8 Z of vcry black Aßies, thewhich bei ngbaked again for 8 Days continually in a Brick Furnace asterthe Lye was made, there could net be a Grain of Sah Drawn. The likehappen’d in 10 of Aßies Drawn from a Stare and a half of Bran, burntfirst in the Furnace wich Sulphur, and afrcrwards baked in a Potter’s Oven,and in onc of Bricks.

16 All the Salts whatever Drawn from the Aßes of Feget abies, taken bytheMouth, says he, have a Purging Faculty, and a great measore more thanwhat by semc is believed in Common Sah , which taken by the Mouth haslittle or none at all ; or if it have any, betwixt that of Common Sah andVegetables, the Proportion is but as Two to Eight.

i 7, This Solutive Faculty is of equal Energy in all the Salts, in suchtmannet that the Saltos Sumxck, Veels of Pomegranates, Myrtle Berries, orMaß ick, Purges as much as the Sah ofRhubarb, Sena, Turbith, Mechoacan,and all other like Purgative Drugs.

1 8. The Dose to be used is the säme in all the Saht, to wir, from1 Dracbms and a half to half an Ounce, Diffolved in 6 Ounces of CommonWater and Broth ; he has observcd by infinite Experiments, that half zuOunce uses to Purge 3 A. and a half, or 4 or thereabouts of Matter, raore orless, according to the Complcxions, and according to the Fulness of theLodies.

19. In the Purging he has found no Differente betwixt thefe Salts thathave stiarp Points, and thosc that are Obtuse and Blunt or Cubical; he hasmade proof very often in divers Perlons, caufing the like Cubical Stcnes ofCucumbers, Gtnger, Colewort, and of Liquorsßi , to be picked out, and he hassene that they have JVorked with the same Energy as the most Acute Hex*agone Stones of the Salt of Pepper, of Carnation Roses, of Mechoacan, ofColeworts , of Cucumbers, See.

io. From the aforesaid Observations, tbough you cannot Establifii a cer-ta in Pule, you may neverthelesi Conjecture, not without sbme Reasön, Fsrjfthat ehe Salts drawn from the Aßes of Herbs, Flowers and of Frusts, See. donot Conserve the Viftue, and that Faculty which Physicians believe theHerbs , Flowers, Fruits, See. Endowed with , Secondly, You may verynear be certain of the Proportion of Aßies rising from each Species of Fege-tables, and of the Quantity of Salt which is afterwards to be Drawn fromthem.

21. You may also obfirve that sbme Vegetables Insipid and Cold, as E»-dive, Pompion, and Roses, have given much more Salt than others of astronger Savour, Aperitive, and Incisive, as the Onions, Hellebore, Lawrtl,Maiden-Hair • and Garlick, which is so strong, gives none at all: But itmay perchance be seid, that in these there is a greater Quantity ofFolatlle Salt.
