I knpute to the Cinabars conftringing its parts, tho* 1 
think Lac ’per fe has the greateft Eleftricity, both having 
all or moft of the Properties ot Amber 5 and by all the 
Tryals I have hitherto made of Lac and Sealing-Wax, I 
find that tho* -the Cracklings are as plentiful in the day 
time, as when the Sun is down, yet in the darkeft Places 
I coud difeover but a little appearance ot Lighr, fo that 
this deferves the Name of a NodHluca or Phofphornt, as 
well as the others already fpoken of, it being no other 
than a Vegetable coagulated with an Animal Vo- 
latile Acidam. I don’t know in the Animal Kingdom, 
any thing but Pifmires that affords a Volatile Acid, and 
in the Eafi-L/dies there’s a large kind of em, that live 
on the Sap of certain Plants, affording both a Gum and 
a Colour, which Sap paffing thro* the Body of thofe^ 
Infers or Animals, is by their Acid Spirit converted into 
an Animal Nature^ which is the rcafonthat with the Co- 
lour extracted from Gnm Lac (which Lac is nothing 
elfe but the Excrements of thefe Infeds or Animals) al- 
rnoft as good and full as lafling Colours are made as from 
.Cochif^ele: I’m the uiorc confirmed herein, becaufe 1 
know of an Artificial way of converting Vegetable Co- 
louis into an Animal Nature very much like this, by 
which the Colours are made more pleafant and perma- 
nent, the Method v/hereof I fhall forbear mentioning 
at prefen f, and refer it to wdiat I may hereafter have oc- 
cafion to write in relation to Colours. After the fame 
manner the remaining Gum, which is an Oleofam^ being 
digefied and paffing thro’ the Bodies of thofe Infeds or 
Animals, is by their Volatile Acid converted into a Ve- 
getable-Animal Phofphorm^ or No&iluca ^ the Artificial 
Phofphorns is a Mineral- Animal Phofphorus, wdaereas I 
take the others to be altogether Mineral. 
Perhaps, Sir, this hafty and fhort Account of my Ob- 
fervations may by fome be thought little better than a
