az. ¢. The Cryfials of Marine Salt of Scruvygrafs are fomewhat 
like to thofe of Rofezary now defcribed. 
22. §. As for the Lixivial Salts of Afh and Tartar, though ina 
Month of Five Weeks Space, they yield fome Cry/fals of very clear 
Salt: yet of Marine Salt neither of them yieldeth the leaft particle. 
So that of thefe Six Léxivial Salts, fc. of Rofemary, Scurvygrafs, Black, 
Thorn, Wormwood, Afh and Tartar, all, but that of Tartar, yielded an 
Effential salt. And all, but thofe of A and Tartar, yielded a Ma- 
vine, {uch as is above defcribed. All which Salts both Effential and 
Marine, together with their Models, made of white Alabaftre, I have 
here ready to be feen. 
23. §. . Of thofe that yield thefe salts, or either of them, it is 
fartherto be noted, That there is a confiderable difference in the 
Proportion or Quantities which they yield.. The Rofémary yields ftore 
both of Efeéntial and Marine, but more Effential. Wormwood and scurs 
vygrafs more Marine. Black Thorn \efs of Either: The Af no 
Marine , and the Tartar neither the Eential nor Marine, as hath 
been faid. 
24. §, From what hath been faid, I deduce only at prefent thefe 
Three Coralie. Firft, That a Lixivial Salt, is not only a compoun- 
ded Body /e. ofSalt, Sulphur, Aer and Earth; but even a Compounded 
Suit, containing both a Vegetable Nitre, anda true Sea Salt. 
25. §. Secondly, That the Expofing of Bodies, in the manner 
above fhewed, may juftly be accounted one Part of Chymsifiry hithetto- 
Deficient, and much farther to be improved for the Difcovery of the Na- 
ture of Bodies. For as Nature chiefly compoundeth Bodies by Digefting 
them, and fo either fhutting out or keeping inthe der: So fhe Die 
folveth them by Expofing, and {o neither fhutting in the Aer, nor keep- 
ing it out, but leaving it free to come and go; and thereby to bring, 
and carry off whatfoever is neceflary for the Separation or Solution of 
Bodies. For the Sea it felf (to confine the fimilitude to our prefent cafe ) 
is but as a Great Pam, wherein all kinds of bodies being long expofeds 
are throughly refolved, ultimately yielding from the reft of their vi- 
fible Principles, that which we call Sea Salt. : 
26. §. Laftly, if by Expofing and Difoloing we can make oneSatls 
then by Compounding and Digefling we may make another, yea any 
other Sait; either a Fixed of a Volatile,or a Volatile of a Fixed. That 
isto {ay,a Volatile Salt may be fo feparated from other Bodies, as to be- 
come Fixed 3 ora Fixed Salt may be fo mixed with other Bodies as to 
become Volatile. For that any Salt fhould of it felf become Fixed or 
Volatile, isa Fixion not grounded upon Experiment. 
27. §. As for the Virtue of the Efential salts above deferibed, I 
believe they will be found upon tryal, not contemptible in fome 
Cafes, For which among(t other reafons, I have been the more punétual
