of a ligature on Cataputia minor Lob elMz^xht fudden /pringing 
of the Milky juice out of infinite pores befidcs the Incifion ; 
(thecaufeof which Phcenomenon 1 take to be ^ the diffedled 
veins iinpecuoufly difcharging themfelves of part of their 
juice within the porous Parenchyma of the Bark 5) whence it is 
probable 5 that, if there was no. coated veflTel to hold this 
milky juice, we might well expe6t its fpringing upon the bare 
ligature, as when we fqueez a wet Sponge ; the external Cu- 
ticle of the plant, as this Experiment ftiews , being adually 
perforated. 
In the next place it is very probable , that thefe vc^flcls are 
in all Plants whatfocver. For,as it is truth- like of all the orhcr 
fukflantial parts of plants, that they are aSually in y and com- 
mon to all plants 3 though fpecified by divers accidents in 
Figure and Texture ; fo of thefe Veins^ which, though they 
be difcern^ble moftlyin thofe plants where they hold 
louredjmces^ yet we may very probably think, that they are 
wanting, where the eye finds not that affiftance in the chal- 
lenging of them. As in thefe very plants, where they are leajl 
vifible, there is yet a time when they are, if not in all , yet in 
fome parts of thefe plants , plain enough to the naked eye : 
The tender flioots of the Greater and Lefler MapU ^ in May, 
are full of a milky juice ; vi^^ the known liquor of. thefe Veins^ 
Again to this purpofe. If you apply a clean knive- blade to a 
traverscut of the like Shoots of Elder , the Gummy I quor of 
thefe Veins will be drawn forth into vifible firings 5 as is the 
nature of Bird-lime, of the bark of Hollf, or the milk of Cata- 
putia minor Lobel. Further, The leaf ftalksof our G^/'^wi^/^- 
barb do fometimes flioot ( by what accident , we enquire not 
here) a tranfparent and very pureChryftallin G2^;72w , though 
the Veins, that held this gummy juice, are by no ordinary 
means vifible in themj and yet by comparing the nature and 
properties of this Gum , with that of the Gumsof other Ve- 
getables, we cannot doubt but this Gum-J^ubaxb is the juice of 
thefe Veins, as well as we are allured, the Gum of other Ve- 
getables to be of theirs^ by the fame comparative Anatomy* 
Laftly^ we think,that even Mujhromts(th2it feemingly inferiour 
and imperfeft order of Vegetables ) are not exempt and 
defticuce
