a very few were like Triangles^ .which had the Angles 
cut off ; as E. Where the water had coatiaued long, there 
were feverall fix fided figures, as big as a fmall Sand; as 
amongtheretti^ Alfo fome fquare pieces of Salt, like a 
looking Glafs with a Border about it, as Fig. G. 
ALLUM. 
1 put fome Jllum in rain water, and obferved therein 
very fmall figures, whofe bafes were Hexangular, the 
fides rifing up Pyramidall, like a pointed Hexaiigular

magnitudes, and fome feemed plain without any rifing, 
r as 55. There were alio fix fided figures irregular, as 
G and D. But as the water began to be evaporated,

and the Salts run together as big as Sands, growing un-

gures, asF. having in the middle, other fmall fix fided 
figures rifing Pyramidally. 
SALT-'PETER,

fqaare, and rifing into a Pyramid. There were alfo fi-
