1 24. That Salts are the principal Ingredients of ftones^ I think 
has fofuiiiciently been noted already, that to 'endeavor any fur-* 
ther evidence of the would he a^u?n agere in me, andlofs 
of time to the Reader : And if of Jiones in general, much ra- , 
ther i^ure of formed ones^ it being the undoubted prerogative of ' 
the Saline Frincipk to gis e Bodies their figure^ as well as folidity 
and duration : No other principle that we yet know of naturally | 
{Looting mno figures^ each peculiar to their own kind, but falts ; ' 
thus Nitre always shoots into Pyramids, fait Marine into Cubes^ 
Alum into o5fo^ and Sal Armoniac into Htxaedrums ^ and other 
mixty^//i" into as mixty^^/m. 
125. Of thefe fpontaneous inclinations of falts^ each pecu- 
liar to its //W, we have further evidence in the C^j^^zic^/ Anato- 
my of Animals^ particularly in the volatile fait of Harts-horn^ 
which in the beginning of its afcent is always feen branched in 
the head of the Cucurbit like the natural Horn, And we were 
told the laft Term by our very Ingenious and Learned Sidleyan 
Frofejfcr here in Oxon, That the fait of Vipers afcends in like 
manner, and shoots into fiapes fom what like thofe Animals, pla- 
ced orderly in the glafl. Thus in congelations which are all 
wrought by adventitious falts^ we frequently find curious r^jwi/f- :jj 
cations^ as on Glafs-windows in winter, and the figured flakes 
offnovc^; of which Mr. obferved above an hundred feveral 
forts, yet all of them branched as we paint fiars^ with fix prin- j 
cipal Radii of equal length, shape, and make, iffuing from a cen- 
ter where they are all joined in angles of 60 degrees, j 
126. Whztfalt it Hiouldbe that gives this ^gure^ though it be I 
hard to determin, yet certainly it muft not be a much different 
one from that which gives form to our AJlroites and i4/?er/>,where- 
of, though the latter have but five and therefore making 
angles where they are joyned at the center of 72 degrees ; yet the 
A§iroites both in mez^ Rilievo and Intagliy as in Tab, 2. have ma- 
ny more. Perhaps there may be fomthing of an Antimonial fait 
that may determin Bodies to this i^^rr)' figure, as no queftion it 
do's in the Regulu6^ and the Caput mortuum of the Cinnabar of An^ ■ 
timony. To loch a fait may alfo be referr'd our Brontice or Om-
