is, that a young Man or Woman, from 20 to 30, 
being electrified during five Hours, loft feveral 
Ounces of their Weight, more than they were wont 
to lofe, when they were not electrified. Thefe laft 
Experiments are difficult to purfue with .Exactnefs; 
becaule the Cloathing, which cannot flrictly be com- 
pared to the Hair or Feathers of Animals, retains a 
good Share of the perfpired Matter, and hinders 
one from forming a good Judgment of the whole 
Effect of the electrical Virtue. 
This forced electric Perfpiration is very naturally 
accounted for, if we confider, that the electrical 
Matter pervades the interior Parts of Bodies, and 
that it vilibly darts from within outward : For it is 
very plain, that thefe electrical Emanations muft 
carry with them whatever they find in the fmall 
Veflels, thro' which they are feen, or at leaft are 
known, to ifiue. 
This Explanation will, in my Opinion, occur to 
every one, who has feen the principal Thanomena 
of Electricity. But how fhall we account for all the 
following Effects ? All thofe Animals, whofe Per- 
fpiration is increafed upon their being electrified, all 
thofe Seeds, which (hoot and grow quicker - y all 
thofe Liquors, which evaporate - y all that Accelera- 
tion of Liquids flowing thro' Tubes ; all thofe Par- 
ticulars, I fay, happen in the fame manner, when, 
inftead of electrifying thofe Bodies themfclves, they 
are only held near electrical Bodies of a pretty large 
Bulk. The Notion which I have, for thefe three 
Years paft, formed of Electricity, not only affords 
me an Explication of this, as Ample as the former, 
but 1 venture to fay, it was this fame Notion, that
