Body and Boughs, and perhaps by wounding then made 
way for frefh Manna. Here I may note, that many Fn- 
feds have not only a Probofcis to bore and draw out the 
Juices of Plants for Aliment, but other proper Indruments 
to convey their Eggs into Vegetables and Animals, where 
they may find Covert and Food when they come to hatch, 
in the Gall-Tumours, and other Excrefcences occafion’d 
by the Wounds of the Parent Fnfeds, that make fuch 
variety of Ctmhuli in all parts of Plants, and even rn 
the cutaneous parts of living Creatures and in dead Flefn. 
This confirms me, that many Gums and Exudations 
find their way out of Vegetables thro’ the Wounds of 
Infeds and other Apertures. Molt Voyagers thro’ the 
Eafl Indies affirm, that Gum Lack is work’d and made 
by large Ants that cover the Trees. I rather think the 
Infeds fuck and terebrate the Tree, and fo give vent to 
that peculiar Sap that hardens in the Sun. This may ex- 
tend to moft Balfamiferous, Gummiferous, and Saccha- 
rine Plants, efpecially in hot Climates where Infeds 
abound, and are more adive. In cold Climates the 
Saps of many Vegetables will boyl into Sugars, as that 
of Maple, Birch, Reeds, &c. Not but that the Fluids 
of Plants (like thofe of Animals) will fpontaneoufly 
break thro' their Veflels in a Plethory, and make on the 
fuperficial Parts various Eruptions and Congeflions. 
Difcourfing of Manna F may here take Notice there 
are many adulterations of this Drug: all paiTes for the 
Calabrian, whereas that of Brianfon is from the I.arix, 
that of Perfia from the Myrica , and thefe frequently 
rmxt with the Juices of Spurges, and other Purgative 
Ingredients. I mud not here deny that Dew will Pome- 
times in cool Mornings fhoot, and congeal into a Polid, 
Pweet, white Subdance, which I once obferv’d in very 
hot Weather before Sun-rife.
