Cortical Thorns are fach as thofe of the Rasberry Buth, be- 
ing not, unleß in a moft extraordinary fmall and invifible proportion 
propagated fromthe Ligwons Body, but as, it feems, wholly from the 
Cortical and Skin, or from the exteriour part of the Barque. 
3. $. The Growth of this Thorn may farther argue what in the 
Second Chapter we {uppoed fe. That as the proper Tendency of the 
Lignous Body, isto fènd; lo of the Cortical to Defeend. For as the 
Lignous Thorn, Nike other Parts of the Trunk , in its Growth afcends; 
This, being almoft wholly Cortical, pointeth downdward. The ufe of 
Hitt. of the Thorns the Ingenious Mr. Sharrock hath obfeved. 
Prop.ofVegets 4. $. Upon the Leaves of divers Plants two Produifions thew 
themfelves, Je. Hairs and Gloubulets. Of Hairs, only one kind is 
taken notice of 5 although they are various. Ordinarily they are of 
a Simple Figure 5 which when fine and thick fet, as on moft Hairy 
Buds; or fineand long, as on thofe of the Vize, we call them Dom». 
5. $. But fometimes they are Branched out, from the bottom to the 
top, reciprocally on every fide, in fome refemblance to a Stags Horns 
asin Mullen. And fometimes they are Aral, as upon Lavender, and 
fome other Leaves, and efpecially thofe ot Wild Olive; wherein every 
Hair rifing in one round entire Bafis a little way above the furface of 
the Leaf, is then difparted, Star-like, into feveral, four, five or fix 
Points, all ftanding at right Angles with the faid perpendicular Bafs, 
6. §. ‚The Ufes of Hairs are for Diftinétion and Protection. That 
of Diftinifion is but fecondary, the Leaves being grown to a confide- 
rable fize. That of Protedfion is the prime, for which they were ori- 
ginally form’d together with the Leaves themfelves, and whofe fer- 
vice they enjoy in their Infant-eftate : For the Hairs being then in form 
of a Down, always very thick fet, thus, give that Proteöfion to the 
Leaves, which their exceeding tendernefs then requires; fo that they 
feem to be velted with a Coat of Frize, or to be kept warm, like 
young and dainty Chickens, in Wool. 
7. $- Globulets are feen upon Orach, both Garden and Wild; 
and yetmore plainly on Mercury or Bonus Henricus, In thee, grow- 
ing almoft upon the whole Plant, and being very large, they are by 
all taken notice of. 
8. $. But ftri& Obfervation difcovers, that thefe Globulets are 
the natural and conftant Off-fpring of very many other Plants. Both 
thefe Globulets, and likewife the diverfity of Hairs, I find that Mr. 
Microgaphy. Hook hath alfo.obferved. I take notice, that they are of two kinds 5 
Tranfparent, asupon the Leaves of Hyjop, Mint, Baume, and many more 
White, as upon thofe of Germander, Sage, and others. All which, 
though the naked Eye will difcover, yet by the help of Glafés we 
may obfervethem molt diftindly. The ufe of thefe we füppofe the 
fame, in part, with thole of the Flower, whereof we {hall (peak.
