Cafalpinus has afligncd one ufe this Liquor is defigned for, viz. 
to fupply the Bees with Materials for their Honey j but Malpighi^ 
whole cautioufnefs in framing Hypothefes concerning the final Caufes 
of Thinirs, is not the lead beautiful Part of his Character, has advanced 
nothing at all about it, but only that it is a wonderful appearance. 
Dr. Woodward in a Memoire prefented to the Royal Society ^ con- 
cerning Vegetation, which both for the accuracy of the Experiments 
it contains, and the juftnefs of the Conclufions drawn from them, 
ought to be reckoned a Pattern and Standard for all Philofophical 
Enquiries, has endeavoured to account Mechanically for the Producli- 
on cf thefe Liquors, or Exfudations of Plants, but fixes no certain 
Receptacle for this we are now upon. It is certain from repeated 
Experiments he has made, that the far greatelt Part of the Juices, that 
enter by the Roots of Plants, is tranfpired through the Pores of them j 
and as fome Particles of this Matter may be fo far attenuated and fc- 
parated from one another, as to be Ipecifically lighter than the Air, 
and fo will mount up into the Atmofpherc ; fo there may be other 
Parts of it fo grofs and heavy, as not to be able to reach any further 
than the Surface of that Part of the Plant, through which they tran- 
fpired ; They willconfequently remain and fettle there ; and from fuch 
Particles condenfed, it is very natural to think this and other fuch Li- 
quors are formed. This Oblcrvation and Reafoning of the Doctor’s, 
concerning the manner in which this Liquor is produced, is much 
more fatisfadory than what either C^efalpinus or Malpighi have told 
us about it j but however contradicts no part of what this laft named 
Author has advanced. 
The next in order of time, who has faid any thing concerning this 
Melleous Liquid is Dr. Blair, and according to him it is a part of 
Plants of very great Importance in Vegetation, After obferving from 
Mr. Bradley that there is a Glutinous Matter on the tops of the Styli, 
which may be capable of receiving and holding fome patt of x\\z farina 
faciindans, as it falls from the MpiceS', he adds, 1 gofofar in with 
Mr. Bradley, that I lhall put him in mind of another Contrivance for 
that purpofe, of which, I doubt nor, he is already fcnfiblc, viz. of 
the Relvis, fo to call it, or Ciftern, fituated at the Root or Origin of 
each Retahim, filled with a vifcuous Liquor which continues there, 
and never exceeds its bounds fo long as the Ret alum is in health ; lor 
fmee the Apices here are fo artfully fixed, that they turn every way 
with the leaft Wind, as Mr. Moreland juftly obferves, when they burft 
and the Farina is driven to and fro, tho' it cannot foeafily enter the nar- 
row Tube, yet it may conveniently be blown up towards the Origin 
of the Retala, where it is flopped or flay'd by this Vil'cofity, till it 
has perform'd its office. 
Mr. Fairchild being perfwaded that this vifcuous Liquor did fome 
way or other contribute towards thefruftifyingof this Plant viz, the 
Corona
