this Seriim came freely from th'^ eher, by fq-jeczmg 
betwixt my Fingers: and the Curds! vvalhed in Spring 
water, which became immediately hke Rags and tough 
(Dr^w this Miik immediately, or let it fall ofT rhe Piant, 
into a Shell of fair Water, orothei Menitriii.jTi, as Vi- 
negar, S. y Spirit of Vitriol or Sulphur, ^c.) and 
remained iiiil white and dry. As for the purple Whey, 
after a Days infolation , it ftifned and became hard, 
and was eafily formed into Cakrr ; which Cakes u ere 
yet very brittle, and \^o\M eafif; crumble into Pow- 
der. About D^cm^<?r' following, 1 broke one of the 
Cakes, made of the cafeous part of the Milk of this 
Plant ; it then proved very brittle, and fhined upon 
breaking hke Rofin ; it was then of a dark brown Co- 
lour ; moreover, it burned with a lafting Flame, like 
Rofin or Wax and that being melted by Hear, it would 
draw out into long tough ftrings, 'like Bird-lime. 
On the contrary, the purplifli Powder, which was the 
Whey, if put into the Flame of a Candle, would 
fcarce burn with a Flame at all, but fopn be turned in- 
to a Coal. Laftly, the purple Powder did tafte very 
bitter whereas the cafeous part was as infipid as 
" Wax. 
Qu. Whether 'the Artifice of Bees doth cot much 
confifl in a way Nature has taught them, to coagulate 
the Juice of Plants , or rather to ftparate and make 
choice of the cafeous part of the Juices of Plants, alrea- 
dy coagulated for their Wax, and the Whey for Ho- 
ney.
