ral; or whether they are not new fubflances, gene- 
rated either in the vefiels of plants by means of 
the vegetative procefs, or by fermentation, or by 
the force of fire. If they owe their origin to the 
mineral acids, they are certainly fo much changed 
in their virtues, and properties by the combination 
of new particles, and by the procefies they have 
undergone, that they may be looked upon as diftindt 
bodies in many refpedts. 
From what has been faid, it is evident that the 
number of true neutral falts * is infinitely greater than 
what has been fuppofed, of late, by chemifts ; and it 
is probable that many of the neutral falts, above de- 
fcribed, may prove to be excellent remedies in the 
cure of difeafes, as well as ufeful in many manu- 
factories. 
As there is fuch a variety of vegetable acids, and 
as each of them produces a diftindt neutral fait 
with each of the three alkalies, I think it would 
be right to diftinguifh them from one another by 
particular names ; the falts made with the vegeta- 
ble alkali may be called vegetable falts , as both th e 
acid and the alkali are vegetable fubftances ; thole 
made with the fofiil alkali neutral falts; and thofe 
made with the volatile alkali ammoniacal falts , as 
all the neutral falts hitherto made with this alkali 
have gone by this name. Thus we _ may call the 
three neutral falts made with lemon juice : i . Ve- 
getable fait of lemons. 2. Neutral fait of lemons. 
3. Ammoniacal fait of lemons. 
* By true neutral fait is meant, a fait made with an acid and 
one of the three alkalies ; the word true is added to thefe falts, 
to diftinguifh them from neutral falts, made with earths or me- 
tals, and acids. p
