Book IV. of Leaves. 151 
5- $. TO make this appear, I (hall give feveral Inftances: of fome, 
where both the Edges are of one Meafure 3 and of others, where they 
are different: And of both kinds, where they are meafured by fewer? 
and where by more Circles. 
6. $. The Leaf of Lagopus major fol. pennat. is meafüred by One 
Circle, the fame on both Edges, whofe Diametre is Thrice the Length 
ofthe Leaf. 
7. §. That of syderitis Salvie fol. by Two Circles: the Diameter 
of the Lower, being Twice the Length of the Leafs of the upper, Tae 
the Length and half. In both thefe the Circles are drawn Outward a 
that is, with their Centers fome where upon the middlemoft or chief 
Fiber ofthe Leaf. 
8. $. That of Orange-Tree, is alfo meafured by Two Circles >, but 
one of them repeated with Oppofite Centers. That next the Cone of 
the Leaf, is drawn Inward ; that is, with the Center no where upon the 
Leaf, but without it. The Diameter hereof is jult the Length of the Tab. 44. 
Leaf. The midle part of the Edge is meafured by the fame Circle, 
only drawn Outward. The lower Circle next the Stalk, is drawn In- 
ward, as the uppers and its Diameter Three times the Length of the 
Leaf. 
A $. The Leaf of the Venetian Vetch, is meafured by Three Cir- 
cles. That next the Cone, drawn Inward; the Diameter whereof, is Tab. 44 
Twice the Length of the Leaf 3 the next is drawn Outward; where- 04% 
of the Diameter, is juft the Length. The third or lowermoft, is drawn 
alfo Outward 5 and its Diameter, half the Length. So that they all 
leffen by an Equal Proportion. 
lo, $. The Leaf of Great Laferwort , is alo mieafured by 
Three Circles 5 all drawn Outward, and one of them Repeated. The 
Diameter of that next the Cone, is Half the Length of the Leafs of the Tab. 45: 
next, Thrice the Length; of the Third, juft the Length; the lower- 
moft, is the fame with the Firft. 
11. $. That of Broad Leav'd Laferwort,is alfo meafured with Three 
Circles; and one of them repeated with Oppofite Centers, The Diame- 
ter of the Firft, is Half the Length of the Leaf; of the Second, Twice Tab. 44; 
the Lengths of the Third, juftthe Length: all of them drawn Out- 
ward. That next the Stalk , is the lame with the Firft; only drawn 
Inward. 
12. $. The Figure of the Leaf of the Cornelian Cherry, is exactly that 
ofthe foregoing, Inverted: the fame meafure there beginning at the 
Baft, and ending at the Cone ; which here beginsat the Cone, and ends 
a ES Bafe: as by comparing their Draughts together may be ob- 
terv d. 
13. $. IN ALL, the foregoing Examples, both the Edges of the 
aves have the fame Adeafure. But they have oftentimes, different 
- ones; asin thefe that follow. 
14. $. The Leaf of Althea fruticofa,is meafured by Three Circles, The 
left Edge (as the Leaf lies with the backfide upward ) by One Circle, 
but Twice repeated. For the Diaweter of the Firft, is the Length of Tab, 45: 
the Leaf’; the Second is the fame, but drawn upon another Center 5 
the Third alfo the fame, but drawn Inward. The right Edg, is mea- 
far'd by Two Circles: the Diameter of the Firft, being the Length of 
the Leaf; of the Second, Half the Length 
Tab. 44:
