in eye-bright, in wormwood, in forrel, and in ilioots of vines 5 
3 ibrts in black pepper, and in incarnate rofes; 4 ibrts in the 
white hellebore. 10. Befides the abovenrientioned divcriity of 
figures which are found in falts, it is obfervable, that amongil: all 
falts, of what figure foever, there are found ibme cubical, which, 
the* they be never fo often diflblred and congealed, appear ftill 
of a cubical figure, or inclining to it. ir. S. Redl knows not 
that it is a general rule, that the different parts of herbs, fruits, 
^c. make a diverfity in the figure of their falts ; but he fays, 
particularly, that the falts of the leaves of laurel differ from that 
of the wood, and that the figure of the ialt of the pulp of a 
gourd differs from that of the rind. 12. Many falts of different 
matter have the fame, or at leall: very like figures j the fait of 
cucumbers hath a figure like the fait o^ Eye -bright ^ Mechoacan^ 
Scopa^ and Lettice-^ alfo all the fait of orange-flowers, rofes, 
ginger, endive, ^Colloqulntiddy Scorzofiera root, white hellebore 
roots and liquorilh are all like one another 5 coleworts and 
rofemary-flowers yield a fait of one and the fame figure, as like- 
wile do among themleives vine-branches, Ibrrel, black pepper, 
the rind of pomegranates, and the roots of black hellebore, 
15. To make the bodies of the falts, when they congeal, remain 
diftin»Sl from each other, lb as that their figures may be obierved, 
and not be entangled and heaped together 5 it is necelTary, that 
very great diligence be ufed in evaporating the lee ; for if that be 
wholly evaporated, or too great a part thereof, the llilrs make a 
confufed cruft at the bottom of the vefTel- if the lees are left too 
weak, the lalts require a very long time to congeal, and therefore 
it is requifite to ule fuch diligence as is not to be gained without 
long pradlice: The inilruments for determining the weights of 
liquids may give a rule, which if not general, will at lealt come 
very near the matter : The lees being reduced to a proper thick- 
nefs, are put into little fmall glafles clofed with a flopple, and ^ 
kept in a very dry place, and you may expert that in time the 
falts will congeal into cryftalline flioots, either in the bottom, or 
on the fides of the veflel. 14. All forts of herbs, flowers, fruitwS, 
or woods, when they are burnt, do not yield equally the lame 
quantity of fair, but according to the diverfity of their fpecies, the 
quantity of fait drawn from their afhes, is found difR^rent; the 
ieaibns wherein the plants are gathered, occafion a great diver- 
fity as alfo does the country, whether mount^Blious or champaign, 
fea-coaft, marfhy or moift. 15. All bodies burnt, yield not the 
fame quantity of afhes^ but there is a great diverfity, which you 
may lee by the followipg proofs ;
