their fragility, are capable of winding about another, without being 
torn all to pieces. For which end alfo, thefe Thorws grow not like 
Buds, erected but poynt all downwards, like fo many Testers or 
Hanging-hooks : as in the Bramble, chiefly on the stalks 5 and in Chivers, Tab, 43. 
alfo on the Leaves themfelves ; whereby they catch at any Thing that 
ftands next them; and fo, although fuch flim and feeble Plants, yet 
eafily climb to a very great hight. 
8 §. OF THE feveral Figures of Hairs, and their Ufe, Ihave B. 1.Ch. 4, 
alfo fpoken. Astoone Ufe, fc. the Protection they give to the Leaf, Tzb. 43. ‘ 
I thall here further note, That the defign of Natwre, is the more evi- 
dent if we confider, That all Leaves are not alike Hairy, nor at all 
times, nor in every part : but differently, according to their Age, Sub- 
fiance, Texture, and Foulding up. Their Ages for there are many 
young Buds covered with a thick warm Hair, which afterwards dries 
up and difappears, as ufelefs5 as thofe of the Vine, Gulden Liverwort, 
&e. Their Subftances fo thofe Buds which are tendereft, and would 
fooner feel the cold, if naked, have the fulleft Hair; as of Thi/tle, 
Mullen, Burdock, and others. Their Struéfure 5 therefore thofe Leaves, 
whofe Fibres {tand more prominent or above their Surfice, left the 
cold fhould nip them, are covered with greater Store of Hair; as in 
Moth-Mullen, Garden-Clary, and the like. And their Foulds it being 
obfervable, That thofe Leaves which are folded up inward, have little 
or no Hair on their inner, but only on their Back-Sides, which are 
open to the Aers as is vifible in Coring Warden, Golden Liverwort; 
and others. os 
9. §. Add hereto, That where there is Store of Hair, Nature is 
the le follicitous for other Covers 5 and where there is not, fhe is more. 
Sothe Lesves of Beans and Peafen, of Netile, Plantain, &c. not being 
Hairy, have each a Surfojl, or elfe certain Hairy Thrums, to protect 
them. And thofe Plants which have neither, are fuch as have a Hotter 
Fuyce, and folefs fubject to the impreflions of Cold, as Speerwort, Scur- 
wgraft, Watercreft, Fenil, and moft of the Unabelliferous Kind. 
10. §. Hairis of ufe to preferve young Brds, not only, from the 
cold Aer, but alfo from too much Wet; which, if it were contiguous, 
efpecially in Winter, would often rot and deftroy them. But being 
made to ftand off in drops at the ends of the Hair, doth not hurt, 
but refreth them. Thus doth Nature make the meaneft Things fome- 
times fubferve to the beft Ends.
