P hilofophical History of Plants. 
Corny the juyce whereof is fo Vifcous, that the twentieth part ‘of 4 
Grain, willl draw out above a Yard in length. Oyless not only in 
Seeds,, and fome Fruzts, but other Parts as in certain little cavities in 
the Leaves of Savine, vifibly- collected while they are growing. Gumms 
or Refives; as in Pine, Fir, and others of this Kind. Milks 5 as 
imavaftnumber of Plants, and amongft them, many not fufpected to 
yicld) any. For, of Herbs, not only moft ofthe Ombelliiyerous Kind, 
are Milkys but all or moft of the Intybows 5 Poppys ; Tracheliums 5 
Perwinkles', divers\Thiftles 5 and even Oxions, if cut at the bottome; 
with agreat many more. Of Trees, not only the Little azple, but 
the: young Shoots of Lawrel, efpecially being crufied; as alfo thofe of 
Elder} and:fome others. To which’ may be added, fuch Mucilages, 
which though not fo properly contained’ within the Parts, yet are 
found lying over them 5 as over the firft Spring-leaves of all kinds of 
Docks 3 betwixt the Leaves and the Veil wherein they are involved. 
That fine white: Flower or Powder, which lies over the Leaves of fome 
Plants, as of Bears-Ear: And in Princes-Feather, about certain Aper= 
tures only-on the edges of the Leaves. 
22... Ofvall thefe fhould be obferved, jirf? their Receptacles 5 
fome of them, being proper to one; others, common totwo or more 
oftthem: fince it iscertain, that fome of them do Tranfmigrate from 
one; intoanother Receptacle, or that the fame Receptacle is filled with 
Fluid Bodies, of a' quite different Nature, at the different Seafons of 
the Year, and Ages of the Vegetable. And it is alfo very probable, That 
two of fome of them, may, fometimes, be contained in one Receptacle, 
at the fame time 3 as in Azimals, the Lympha inthe D. Thoracicus, and. 
that, and the Chyle, inthe Sanguineous Veffels. 
23. §. Then'their Motions both Natural, and fuch as ‘may be 
effected by Art : and thofé either by Defcent or Afcent; And in 
afcending, through what different Chanels or Parts of the Truk; fince 
itis certain, That there isa variety, bothin refpeat of the Seafon, and 
of Vegetables. Where it will fall in, To obferve the Tapping of Trees. 
Asalfotheir Bleeding: to what Trees it is proper to bleed: in thofe to 
which it is,with what difference of Celerity: and when their peculiar 
Seafow: fornone will bleed at all times; neither will all bleed at the 
fame... And then'their Collateral’ Moitow, together with the Mode of 
their Tranfition from'one Organical Part to: another. 
24. g. Next their Quantities, either of ove 5 asthe Comparifon 
is made betwixt feveral Plavts, or betwixt ‘the Parts of the fame. So 
the:true Seed of all Plants, containeth more Oyl, in proportion, ‘than 
any of the other Parts. Or elfe of divers,: as coexiftentand bearing fuch 
a_-proportion one to another in the fame Part: of moft of which, it 
maybe known by their refpe€tive Receptacles. Yet the Computati- 
on muft not be made from the number of the faid Receptacles, imply 5 
but as that is in conjunétion with their Capacity; and as their'Capacity 
is: proportioned to their furrounding Sides; the Sides of thofe of the 
leaft Capacity, being ufually as thick, asthofe of the greateft: fo that 
fup pofe Ten leffer,. tolye within thecompafs of One greatersthe Con- 
gi! of thefe altogether, would fearce be'equal to half the Content of 
that:One.
