From thefe experiments our author obferves, that 
the electricity diminifhes the weight of folid bodies, 
if thefe are impregnated with humours liable to eva- 
porate : for the dry wood, metals, and other bodies, 
which feem to have no fluids, lofe nothing of their 
weight; and therefore it is only upon the fluids in 
them that the electricity operates. 
Our author then exhibits fome experiments made 
by perfons of credit, in order to difcover, whether or 
no electricity would accelerate the growth of plants ; 
and from feveral trials found that it did. There then 
follows a feries of experiments, which prove, that 
eledtricity augments the tranfpiration of animals. 
Thefe experiments were made upon puppies, pigeons, 
yellowhammers, and chaffinches ; and the effcCts of 
thofe eleCtrifed, compared with thofe of the fame 
kind, which were not, evince, that electricity does 
increafe the tranfpiration of animals. Cur author 
« here has annexed feveral curious tables, comparing 
the lofs of weight of the animals, while eledtrifing, 
to what they lofe in the fame time without eledtrifing. 
Whoever therefore is defirous of penning them, muff 
confuit the work itfelf. 
Dr. Bohadfch proceeds to give us a theory of thofe 
diftempers, in which eledtricity feems to have the 
greateft effeCts. He confines himfelf however more 
particularly to the hemiplegia ■ of which diftemper 
he gives us the hiftory, correfponding with what we 
find in the heft medical writers. He likewife gives 
us the ufual method of cure, and fhews, that the 
attempts of relieving this malady by eledtric ty, 
nearly Iq .are intentionally with the remedies molt 
celebrated in practice. That the electrical fjparks
