pofllble, yet the Flo\Ver blew out the fame as if no- 
thing had happen'd, till about the Time that the Fa- 
rina might befuppofed to a£l; then the Fetala began 
to look black next the Stylus y and dropp'd off a Day 
fooner than the regular blowing Flower. 
Not having an Opportunity of purfuing this further, 
for want of Flowers and warm Weather, I applied 
myfelf to the Experiments of Mr. Needham , men- 
tioned p . 74. I brufh'd off fome dry Farina , and, 
putting Thames -Water to it, found it would not burft, 
under the Space of 7 or 8 Minutes, and not till they 
are foak'd in the Liquid: For, at the Time of afling, 
they feldom or ever lie one upon another, but 
float off, till they are clear of all Incumbrances. 
But I obferved one Particular, which fecms intirely 
to have efcaped Mr. Needham y which was, That, on 
the Application of Water, they inftantly emit a pel- 
lucid kind of Matter (much thinner than that at 
burfting) thro’ their capillary Prickles, with which 
they are thick fet. Upon the Application of Briftol 
Water they are found to burft much fooner, and 
with lefs Emiflion. In Vinegar they fcarce ever burft 5 
at leaft, if they attempt it, are inftantly flopp'd by 
the Sharpnefs of the Liquor. I don't find Vinegar to 
have any other EfFeft than this. 
In making my Experiments on a frefh-blown Holly- 
hock, I obferved a Lufus Nature of two Globules 
quite fmooth and {Tuning (contrary to their Nature, 
which is rough) : One of thefe acted very foon, the 
other not at all. The whole Farina feem to me to 
have a ftrong Su&ion; for I was obliged, in the Space 
of ten Minutes, to apply Water three times, in order 
for them to have enough to a Qc in 5 and I obferve,
