Hauksbee, Francis, An experiment touching the 
proportion of the weight of air to the weight 
of a like bulk of water, without knowing the 
quantity of either 
— Experiment fhewing that the feemingly fpon- 
taneous afeenfion of water in fmall tubes open 
at both ends is the fame in vacuo as in the 
open air - 
■ — — An experiment touching the produ&ion of a 
confiderable light upon a flight attrition of 
the hands on a glafs globe exhaufted of its air; 
with other remarkable occurrences 
- — An experiment touching the extraordinary elec- 
tricity of glafs, produceable on a fmart at- 
trition of it, with a continuation of experi- 
ments on the fame fubjedl, and other phasno- 
mena - 
- ■ ■■ Several experiments {hewing the ftrange ef- 
fe£ls of the effluvia of glafs, produceable on the 
motion and attrition of it 
— — An experiment touching the quantity of air 
produced from a certain quantity of gun- 
powder fired in common air 
— An experiment fhewing that the fprings or 
conftituent parts of air are capable to fuffer 
fuch diforder, by a violent impulfe, as to re- 
quire time to recover their natural {late 
— ■ — An experiment touching the produ£lion of 
light, by the effluvia of one glafs failing on 
another in motion 
«— An experiment touching the difficulty of fepa- 
rating two hemifpheres, upon the inie&ing 
of an atmofphere of air on their outward 
furfaces, without withdrawing the included 
air 
■ The repetition of an experiment, touching mo- 
tion given bodies included in a glafs, by the 
approach of a finger near its outfide; with 
other experiments on the effluvia of glafs 
*— Some experiments touching the ele£lricity and 
light producible on the attrition of feveral 
bodies - 
«— An experiment touching the different denfi- 
ties of the air from the greateft natural heat 
to the greateft natural cold in this climate
