а. Whereas all other Alkali's of Wood made thus 
by Incineration, are blackifh at firft, and a Lixivium 
made of them, although often filtred, will yet be 
tinged with a brown colour, occafioned from a kind 
of Coal, or Afhes fo inclofed, or clofely united to 
the Alkali in burning, as not eafily to be feparated 
by Filtration, though often repeated ; yet this Aikali 
was very white, even before Solution, and when 
diflolved, the Lixivium was not in the lead tinged, 
but clear like pure Water, only a very (mall quantity 
of Allies fubfided to the bottom of the VefTel, in which 
the Solution was made. The Lixivium thence decan- 
ted needed no Filtration, but when boiled up to Dry- 
nefs, the Salt remained fine and white- And 
3. That in the burning of this Wood , as the 
heat of the Fire grew more intenfe, the Wood did, 
as it were, melt and dodder together in great Lumps, 
and did vifibly bubble, and boil, with an hiding nolle, 
like the Frying of Fat in a Pan. 
4. That w 7 hereas the Weight of the Alkali-Salt pro- 
duced from ether Wood, in the common way of In- 
cineration, is very inconfiderable, in proportion to 
the weight of the Wood producing it ; yet this Salt 
nearly equalled in weight the Wood from w 7 hence it 
was taken. 
5. Whereas the Aflies of other Wood are never to 
replete with Salt, as that Salt can be feen, or in the 
leaft caufe the Afhes to lump or dodder together j 
yet this, the w 7 hole of it, would gather into hard and 
ifolid Lumps of white Salt, as eafily to be diftinguifhed 
from Allies (tho’ white) as the pureft Salt of Tartar 
made with Nitre w r ould be. 
б. That although from other Rotten Wood much lefs 
of an Alkali can be produced, than from Sound Wood , 
yet here it is quite contrary, the decay’d part of this
