Component Particles of Salts. 2§ 
for the Separation of a Salt from the Fluid 
wherein it is diffolved, but an Inlin'ation 
of the Planes of the fmalkft Particles to 
unite ; which Inclination being alike in all, 
jthey ioin one after another on every Side: 
by which means the S.ze grows larger, but 
the Figure alters not. Thoie in common 
Salt he affirms to be minute Cubes, in 
Vitriol Parallelepipeds, and in Nitre hexa¬ 
gonal Prifrns. 
Hence lie infers, that the Figures of the 
Cry dais prove not only the Exigence and 
Shape of their component Particles, but 
withal demondrate that the Crydals are 
thernfelves produced by an appofite Union 
of fuch-like figur’d Particles, whofe Figures 
cannot bedeftroyed unlefs by Annihilation. 
That the mod minute Cry dais difeerni- 
ble by the Microfcope maybe obferved grow¬ 
ing under the Eye, and enlarging their Di- 
mendons many thoufands of times without 
an Alteration in Figure, I dare affirm from 
$ny own Experience : but I pretend not 
thereby to determine the real Shape of the 
original Particles of any Salt, or to under- 
dand the other Properties concerned in their 
Combination, After all my Experiments, I 
am too fenfible of my own Ignorance to fet 
up any Hypothefis : that I leave to abler 
Judges, on future Trials ; begging Leave 
indead thereof to fubmit the following 
Queries to be confidered at Leifure.
