To confirm the Ufe of this Sea-Gage, fhewn before 
to the Society, I made another Experiment in the fol- 
lowing Manner. Having pour’d feme Quick-fiver in- 
to the Bottle of the Gage, I pour’d on upon it Treacle 
to the Depth of half an Inch, then ferew’d on the 
Brafs Cap of the Bottle to which theGlafs Gage-Tube 
was cemented ; by which Means the open End of the 
Tube was brought under the Surface of the Mercury, 
the fealed End being upwards. The Machine, thus fit- 
ted, was immers’d in a cylindrick VelTel of Water, which 
with a Plate at Top wasprefs’d between two Pillars, in 
fuch Manner that Air might be condens’d over the Wa- 
ter without efcaping. Then having forc’d in fo much 
Air with a Syringe, as to lay on a PrefTure equal to 
what would be in a Depth of 40 Foot of Water, I 
open’d the Cock of the upper Plate, let out the Air, 
and, upon taking out the Machine, it appear’d how high 
the Qpick-fllver had rifen in the Gage-Tube, by the 
greafy Mark which the Treacle left within.
