If this purple Juice be Coagulate, it is referrable 
to the next (brt of Juices, viz, thofe which cake alto-

Divers parts of the fame Plant have divers Faculties^ 
F, C. F, A, in App. T^f^o, & 4x. i add. That divers 
parts of the fame Plant yield , from the fame Veins, 
different Coloured Juices, v.g, the Milk in the Root 
of Spond'ilium Ger, is of a Brimftone Colour, but in 
the Stalk White : Yet I make a Queftion, if the Juice 
of the Leaves of Betomca^ in Spring, will not Work 
by Vomit and Seat as well as the Roots, which ought 
to be tryed. 
Amongft thofe Juices which Coagulate and are Clam J^^^^^iP^^-

In the middle of July, I drew and gathered of the^^^^^' 
Milk of LaUuta fyl cofta fpinofa, C, B, and of all our 
Englip? Plants, )that ! have yet met with, this moik Latiucafyi 
freely and plentifully affords it. It fprings out of the 
Wound thick as Cream and Ropes, and is White, and 
yet the Milk which came out of the Wounds, made 
towards the^ top of the Plant, was plainly ftreaked or 
mixt with a purple Juice, as though one had daflied 
or fprinkled Cream with a few drops of Claret, And 
indeed, the Skin of the Plant thereabouts was purpliih 
' alfo, perhaps with Veins, Again, in the Shell I drew 
it, it turned ftill yellower and thicker, and by and by 
curdled, that is, she white and thick cafeous part did fe- 
parate from a thin purple Whey. So the Blood alfo of 
Animals, whilft warm remains liquid and alike, but lb . 
' foon as cold, it cakes and has a Serum or Whey feparated 
from it ; the Cake is made of glutinous Fibers, and 
therefore if the hot or new drawp Blood be well ftir- 
red or beaten, it will not break. Qu. If the fame ftif? 
ring the Milk for ex. of Lac. fyi in drawing it into the
