quired a deep Blew tinSore; There it ftovxl about twelve daies, 
before that'tindure, which decayed but flowly, did little by 
little grow fo diluted that the liquor was pale and alnioft like wa- 
ter : During this (lay of the Glafs in the window, the Mercury 
in theopen leg appeared to be impell'd up, and when after nine 
a clock at night, (which time I chofe to try whether the Nofturnal 
Air,asNofturnal, v/ouldhaveany thing to do with the Ph<£non>e- 
n n,) the Hermetic Seal was broken off; immediately upon which 
there was produced a noife , and the Mercury in the ftorter and 
clofed leg was briskly impel I'd up, by our guefs, near three eights 
of an Inch, and though the Orifice at which the Air had acctrs was 
fcarce wide enough to admit a middle feized pea, yet within a 
minute and half the furfacc of the liquor being held between the 
Eye and the Candle, appeared to have acquired a very lovely and 
fair Colour, which reached downwards a quarter of an Inch ; fo 
that the Vial Teemed to contain two very differing liquors fwim- 
ming on one another , and the Coloration piercing deeper and 
deeper within five Minutes in all, the whole liquor had attained a 
rich Blew colour*] 
With this 'Experiment I Jhallconrfide this Taper: For, though I 
madefeveral other Iryds , with the fame defign that I made the 
foregoing ones, as with Spirit of Niter, and Minium, Spirit of Vi- 
negar and Copper a prefent rvant of time hinders me from trouh^ 
lingyon vpith them^ which Ithe rather forbear todo, hecaufe I fear^ 
they would prove lefs fatisfaHory than thoje I have fet down ; which 
themjelves muft^ to a lefs discerning eye than yours, appear very im* 
perfeU, notwithjianding that prolixity in reciting fome of them\ 
which I was obliged to by v^y not yet knowings in fuch odd attempts y 
what Circumjlances might fafely be omitted. But fuch as they are I 
fend them you, who byyour diffufed Correfpondency have great opfortU" 
nity to get them made, if you think them worth it^ by Curious perfons 
in fever al Countries, various manners, and difering feafons of the 
Tear: And^ however the things \ fend you be but trifles, jet their 
Novelty may perhaps excite the Indupy of other s^ and give rife to 
further Inquiries. '
