Thefe Vefels are admirably fmall, yet througha very good Gla/s become vifible. 15. §. The Liquor conteined in the Seed, when full ripe is chiefly Oyls generally, foundin a greater proportion here, than in any other part of a Plant. Being as the Pickle, in which the Seminal Virtues, z.e. the more volatile and aéfive Principles of the Seed, are immerfed for their Preférvation: and to curb them from too great a Luxuriance in the Vegetation of the Seed, VI ferve and reprefent the Method which Nature ta= keth in its Generation. / ; y Bee SLX CAS 2. §. Inorderto this, the firft thing that is to be be done, done, isis to to make make a fit Uterus.

Forthis purpofe, the. Pulp and Stove of the Fruit are both neceflary 5 but primarily the stove: the meat or Pulp being ro otherwife neceflary, but becaufe the Stove cannot be made without it 3 the petrifying of that Parenchyma which is the Ground of the Stone, being effected, by the finking of the Tartar from the Pulp thereinto. 4. §. And that, at the firft, the Ground of the Stone, is a diftiné, but foft Parenchymas is evident inthe cuting of a young Aprecock. Of which, alfo aflice cut off, with a Rafor, and viewed through a good Gla/s, fheweth it to be compofed of Bludders, as the Pulp it Tah 82, felf’ Only, whereas many of thofe of the Pa/p are Jarge, now about as big. as a white Pepper-Cor: thefe are no bigger than a MuftardSeed. But as the Parenchyma hardens into a Stove, thefe Bladders are all gradually filled up, and difappear. 5- §. This Parenchyma is derived immediately from the Pith, as the Pulp is from the Barque and makes the far greater part of the Stone, “Tis coveredall over within,with a very thin Lining ;derived,not from the Pith but the Parenchyma which covers the Seed- Branch,uponits firft entrance within the hollow of the Stove. This Lining is ofa clofe fubftance 5 yet compofed of Bladders,exquifitely {mall andhardly vifible. By which means, it foon becomes a very hard and dry Body 5 and is Toh. 86, herebyfitted, both to promote the induration ofthe reft ofthe Stove; and the feafonable drying, andfo, the thrinking up, of the Covers of the Seed, to make room for its Growth. 6. §. The Stone being made hard and dry ; it could never be fo fufficiently foftned bylying under gtound, but that, it would keep the Seed a perpetual prifoner, unlefs it were alfo made prettyeafily to cleave intwo.
