a motion, as it were forcibly impelled, till it united with them, making them 

 more and more irregular; of such salt particles, there lay 50 together, and as 

 many more by themselves, being all produced from one drop of water. 



Further, I took at about 2 feet distance from the mouth of the tin and lead 

 oven, out of the chimney which the flame did not reach, a black substance 

 like soot, which I mingled with fair rain water, and let it stand till it was 

 settled ; and in this water I observed there were many irregular figures, whose 

 irregularity I believe proceeded from the want of matter to perfect them, and 

 from the too soon evaporating of the moisture ; I saw likewise many neat, flat, 

 transparent bodies, having each 4 corners sticking out, and 2 inward angles, as 

 N° 11, fig. A: of this sort there were some that I could not see, but with my 

 glasses that magnify most. There were also some figured like a rhomb, and 

 others like a rhomboid, as at fig. B. 



Salt in Quick Lime. — I put some of the quick lime, from Liege, into water; 

 and observed an exceedingly great nnmber of salt particles, but so very small, 

 that I cannot attribute to them any perfect figure, though seeming inclined to 

 a square, and their thickness nearly equal to their length: together with these, 

 were some small figures sharp at both ends, as N° 12, fig. A; others blunt at 

 both ends, as fig. B ; others had 6 complete sides, as fig. C ; and among these, 

 some were so very small, that a globule which makes the redness of the blood, 

 would cover them; these last were as transparent as the finest glass, and as thin 

 as can be imagined; even when 5 or 6 of these particles lay disorderly over one 

 another, their united thickness was still inconsiderable. Also some few figures 

 were shaped like D and E; and some few like F. 



Salt in Lime of Fish Shells. — Of this lime, which is made of sea shells 

 burnt, I mixal a good quantity with water, and letting it stand till it was settled, 

 I took up a drop, which seemed to be as clear as crystal; but I soon perceived 

 figures resembling thin boughs of a tree, without leaves ; their number being 

 so great, that they made the water white and troubled : these are composed of 

 small salts, and'are difficult to be described ; so that I have represented only 

 one small one, N° 13, fig. ABCDE, the breadth of which may be covered 

 with a head hair : the particles of these branchy figures were hexagonal, and 

 when seen edgewise, they showed like F ; some other figures had their upper 

 part quadrilateral ; and others had the basis quadrilateral, and the sides running 

 up like a pointed diamond, as common salt. Others were like IKL, and M; 

 which, lying apart and separate from the rest, were more distinctly to be seen. 

 Other figures were irregular, and could not well be described because of their 

 smallness, and lying so thick and close together. 



Among the innumerable quantity of small salts, contained in a little water.
