34 DireBUns for collecting 
the Phials with good found Corks, on which 
you muft likewise mark the fame Numbers, 
that you may not mi flake the Bottles they 
belong to: and do not think it enough to 
mark the Corks only, for many of the 
Salts will deflroy the Marks upon the 
Corks, and by that means leave you in the 
Dark as to what they contain, unlefs 
there are Papers alfo marked, to help you 
out. 
Make 'then an exact Catalogue of them, 
fetting down each Particular under a Number 
eorrefpondenl to that on the Bottle it is in ^ 
whereby you will at any time find readily 
whatever Solution you want to examine. 
You may range your Bottles in what Order 
you think fit: that in this Treatife is per¬ 
haps as good as any. 
Thefe Preparations will keep good many 
Years ; and when any Phial is almoft out 
it may eafily be replenifhed, fo as to pre- 
ferve your Collection always compleat. You 
muft not expedt to fill all your Bottles 
immediately; forty or fifty Sorts will be 
perhaps as many as you will foon be 
able to procure ; and therefore, if you ft a 11 
be fatisfied with them, your Box may be 
contrived in the above Manner to contain 
only fome filch Number. But a diligent 
Enquirer will be able to add to them from 
Time to Time, and would not willingly be 
limited in his Researches-. Suppofe how¬
