VIII* An Account of a Spirkus Vlni i£thereus," 
together with federal Experiments tried therewith 
!By 'Dr. Frobenius, F. 3^. S. 
I. H E ^ther of Plants appears to be almoft de- 
I ftitute of all grofs Air, from placing it under 
the Receiver of the Air-pump ; for exhauft the Air ever 
fo accurately, this ^therial Liquor remains unmoved, 
nor does it emit any Air-bubbles which immediately 
arife in other Liquors, and according as their Qiian- 
tity of intrinlick Air is greater, fo much the fooner 
arefuch Liquors put into Agitation, and emit alfo more 
Froth, and more vehement Ebullitions in Proportion to 
Vifcidity. 
Hence it follows, that this ^Ether may be preferved 
beft (becaufe without any Diminution) under the Re- 
ceiver in Facuoy whereas on the contrary, expofed to 
the open Air, its Parts foon evaporate, and its whole 
Bulk, but not comprelTed by the Air, vaniflies. (fhts 
Experiment faiVd remarkably.') 
II. A little of it poured on the Surface of like Hand, 
affeds it with a Senfe of Cold equal to that from the 
Contad of Snow, and blow upon it but once or twice 
with your Mouth, immediately your Hand becomes 
dry. Beware however of approaching a lighted Can- 
dle with your Hand thus wet, left it take Fire and ' 
burn you. {Succeeded.) 
III. It caufes fuch a Stridor and Hiffing, poured upon 
hot Water, as is frequently occafioned by a Piece of 
hot Iron thrown into it. Take a Lump of Sugar, 
imbibe fome of this ALthereal Liquor, and put it into
