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 5 and of others, where they 
are different. And of both kinds, where they are meafured by fewer 
andwhere by more Circles. 
6. §. The Leaf of Lagopus major fol. pennat. is meafured by One 
Gircle, the fame on both Edges, whofe Diametre is Thrice the Length 
ofthe Leaf. 
7..§. That of syderitis Salvia fol. by Two Circles: the Diameter 
of the Lower, being Twice the Length of the Leafs of the upper, 
the Length and half. In both thefe the Czrcles are drawn Outward 5 
that is, with their Centers fome where upon the middlemoft or chief 
Fiber of the 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 5 that is, with the Cevter no where upon the 
Leaf, but without it. The Diameter hereof is ju(t the Length of the Tab. 44. 
Leaf. The midle part of the Edge is meafured by the fame Circle, 
only drawn Outward. Thelower Circle next the Stalk, is drawn In- 
ward, as the uppers and its Diameter Three times the Length of the 
Lea. 
4 $. The Leaf of the venetian Vetch, is meafured by Three Cir- 
cles. That next the Cone, drawn Inward; the Diameter whereof, isp 14 
Twice the Length of the Leaf 5 the next is drawn Outward; where-~ “ fas 
of the Diameter, is juft the Length. The third or lowermolt, is drawn 
alfo Outward; and its Diameter, half the Length. So that they all 
leffen by an Equal Proportion. 
to. ¢. The Leaf of Great Laferwort , 1s alfo meafured by 
Three Circles ; all drawn Outward, and one of them Repeated. The 
Diameter of that next the Coe, 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 Laferwortsis alfo meafured with Three 
Circles; and one of them repeated with Oppofite Centers. The Diame- 
ter of the Firlt, is Half the Length of the Leafs of the Second, Twice qh, 44. 
the Lengths of the Third, juftthe Length: all of them drawn Out- 
ward. That next the Stalk, is the fame with the Firfts only drawn 
Inward. 4 
12. §. The Figure of the Leaf of the Cornelian Cherry, is exaGtly that 
ofthe foregoing, Inverted: the fame meafure there beginning at the 7) ,, 
Baje, and ending at the Cone 5 which here beginsat the Cove, and ends 4% 
at the Bafé: as by comparing their Draughts together may be ob- 
fervd. 
13. §. IN ALL, the foregoing Examples, both the Edges of the 
Leaves have the fame Meafure. But they have oftentimes, different 
ones ; as in thefe that follow. 
14. §. TheLeuf of Alibea fruticofa,is meafured by Three Cércles. The 
left Edge (as the Leaf lies with the backfide upward ) by One Czrele, 
but Twice repeated. For the Diameter of the Firft, 1s 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- 
fur'd by Two Circles: the Diameter ofthe Firft; being the Length of 
the Leaf’; of the Second, Half the Length.
