$?4 Component Particles of Salts . 
Gulielminus obferves, that the fenfible Cryf- 
tals of any Salt, however large or minute 
they may be, have always the fame Fi¬ 
gures ; the Co-ordination of the Parts not 
depending on the Quantity of the com¬ 
ponent Matter ; that Nitre, for Example, 
in its Effiorefcences from Walls, difpofes 
itfelf into very fiender Bodies qf the like 
Figure exactly as its larger Cfyfials ; and 
that not only Cryflals too fmall for our Eyes 
to fee, but even the minuted; Particles qf 
their Salt, that were difiolved in the Water 
before their Cryftalization, have the fame 
Figure as the larger Cryftals have. Whence 
he iuppofes the fiifi: Principles of Matter 
whereof the Salt is compofed, and which 
on Account of their Smallnefs nq Force 
can poffibly divide, to have fuch deter¬ 
mined Figures, as they can never change, 
impofed on them at their Creation. And 
for this he quotes Mr. Leeuwenhoek , who 
aflerts, that in Solutions of Cyprian Vitriol, 
and of Tartar, he has feen Particles, which 
though not larger than the twenty thou- 
fandth Part of the Thicknefs of a Hair, 
were exadily figured like their larger Cry- 
flals j and thole Figures in two or three 
Minutes iricjreafed’ to an hundred times their 
former Bulk, ftill retaining their Figure,

other Caufe 
for 
however they were enlarged in 
preadth.
