mfcus was to frame its veficles fo very mi-

of grofs feculent particles, which might be 
injurious to the animal oeconomy. 
This quality of falts ftrongly to attrad 
fulphureous, acid and other noxious particles, 
might make them very beneficial to man- 
kind in many other refpe&s. Thus in fe- 
veral unwholefome trades, as the fmelters 
of metals, the cerufs-makers, the plumbers, 
&c. it might not unlikely be of good fervice 
to them in preferving them in fome meafure
