To an electrified Body I apply a Vefiel full of Li- 
quor, which ifTucs Dtop by Drop thro’ feveral iittle 
Tubes placed in different Parts of its Circumference : 
Thefe Drops become continued Streams, and are ac- 
celerated, as if the Veffel had been electrified : But this 
Effect isobfervable on that Side only which faces the 
electrified Body. 
I moiflen a thick Sponge with Water, and cut it in 
two: I weigh thefe two Halves feparatelyj I join them 
again, and place the whole near a large electrified 
Body, fo as to make one Half of the Sponge face the 
Body directly, and the other the contrary Way. Af- 
ter an Electrification of five or fix Hours, that Half, 
which faced the electric Body, was found to be lighter 
than the other, &c. 
Wherefore I think I have good Grounds to believe, 
that a Man, whoprefentsa Shoulder, or one Side ot 
his Head, to a large electrified Body, perfpires more 
thro’ that Part than thro’ any other. Add to this, that 
fince thefe Animals, which I caufed to perfpire ill 
this laft manner, and which had but one Side of their 
Bodies expofed to the Electricity, loft as much of their 
Weight, as the others which were throughly electrified ; 
it follows, that they perfpired as plentifully thro’ the 
expofed Part, as the others thro' the whole Body. 
Whence we may infer, that, of the two Methods, 
which I propofe for augmenting infenfible Perfpira- 
tion, the latter is the moft powerful, and moft proper 
to remove Obftructions from the Pores, or to fcour 
them of any noxious Humours which they may hap- 
pen to contain. I have the Honour to be, with the 
greateft, Refpect, Sir, 
Tour moft humble and moft obedient Selvant,
