of the Ca/é being lined with a {trong and Tenfed Membrane, they here-

CHAP. VI. 
Of the US E of the Parts to the Fruit. 
gy, N the forgoing Deferiptions, I have already mention’d 
the Ufe of the Parts in fome particulars. ¥ fhall now 
a little further explain the manner of their fervice, 
both to the Fruzf, and to the Seed. 
9 2, 6: And firlt, the Vefels ferve for the Figura- 
~, tion ofthe Frat. So inan Apple, the Ten great and 
DT Wie @ utmiolt Branches ferve not only to nourifh and feed 
it; but alfo, by the Arched Lines they draw, to dire&t and govern the 
Growth thereof into an orbicular Figure. The Dilatation of thefe 
Veffels, not being hindred by any Braces or Conjunéion with the In- 
terior ones. By the Slendernefs of the Aer-Vefels, asin the Root, fo 
here in the Fruit, much promoted. And by their Saline Principle,

3. g. The Five midlemoft and the Five Inmoft ferve together, to 
figure the Goars the former bounding the Outer, the Latter, the Iner 
Angles. For were they only Five, or were all Ten in the fame Cir- 
cle, they would only make a round Cavity like that of a hollow Pith. 
Hence it is that Apples, in which fome fmall Threds of the Vefels ftrike 
out into the Circumference, are very Uneven with divers Kvobs and 
Ridges. But Plums, Cherries, &c. where the Vefféls all terminate at 
an Equal diftance from the Sk, are Even all round about. 
4. §. The Bulk of the Fruit dependeth alfo on the Braces of the 
Vefféls. For in Plums and Cherries, they are more numerous but in 
Apples and Pears they are very loofé one from another, and fo have li- 
berty left them to {pread abroad. . 
5. §. Asalfoon their Sizes that is, onthe Size of the Aer-Veffeli. 
Which, the lefs they are themfelves, they ferve to make a bigger Fruit: 
As the lef they are in any Root, they {erveto make it the more ample. 
For the lefg they are, the more pliable to the Attraition of the Aer : 
and in their Growth muft make fo many more fpiral Rings: by both 
which means, they make the greater Arches. And therefore a Pear is 
commonly a finaller Freétthan an Apple; a Plum than a Pears and a 
Grape, thana Plum; in all which the Aer-Vefels are ftill greater and 
greater.
