ordinary Salt are exceedingly enter¬ 
taining, though its Progreffions are fo very 
flow, that fome Patience is neceffary to wait

Configurations: but a curious Obferver will 
find from it at laft a Pleafure fufficient to 
reward his Attention.—Its firfi: Shootings at 
the Edge of the Drop, after it has been held 
for a few Seconds over the Flame of a Lamp 
or Candle, appear irregular, as at a a , Plate 
V. Some Figures pu£h out foon after, be¬

to a Point, as b b. Very elegant Figures will 
be feen forming themfelves in other Places 
at the fame Time, and refembling Sprigs 
of Fir or Yew: Numbers of thefe rife to¬ 
gether, each having a main Stem very 
thickly befet with little Shootings from Top 
to Bottom, in fome on both Sides, but in 
others on one Side only; which Difference 
■will be underflood by a View of the Figures

in the fame Kind of Form when examined 
by the Microfcope. As the Progreffion goes 
on. Branches will be found iffuing from the 
Sides of the former Shootings, vid. d: and
