the slip of leaf-gold will stand erect, being attracted by the 

 exciied tube ; which shows that th.e top plate is possessed 

 of the lesinous or negative electricity; and the iiold leaves 

 within the glass will at the same time diverge with the 

 vitreous or positive eltciricity, the same as the excited tube. 



But as soon as the excited surface i> removed, the gold- 

 leaves will collapse and instantly diverge again, and when 

 examined will be found to have received the resinous elec- 

 triciiy, the top plate still possessing the same fluid. 



Now, as part of the vitreous fluid has been repelled from 

 the cap through the gold-leaves and tinfoil into the earth, 

 the cap must ne.oes-saiilv possess less of the vitreous than 

 its natural share ; and consequently, when the excited tube 

 is removed, the resinous fluid in the cap will attract the 

 vitreous out of the gold-leaves ; but this bein^ too small 

 a quantity to restore the equilibrium, the cap \\\\\ still con- 

 tinue in a negative slate, and communicate the negative or 

 resinous fluid to the gold-leaves, which will cause them to 

 diverge a second time; and as the cap is insulated it will 

 contmue electrified for some time after, if the instrument 

 be a large one *. 



This experiment also shows, that electricity by induction 

 or position does not vanish as soon as the excited surface 

 is removed, though Professor Robison and other writers 

 on electricity are of a contrary opinion.

LXIII. Case of Hydrophnhia cured in India by Bleeding.

 the Calcutta Government Gazette, June S, 1812.

 REMARKS. 



\Jn hearing that a recovery from hydrophobia ha" been 

 effected in the short space of two hours, by the single re- 

 medy of blood-letlinff, a doubt may probably occur to a 

 person acquainted with the previous history of this formi- 

 dable malady, and the nearly uniform failure of all attempts 

 hitherto made for its cure ; whether the disease now said 

 to be cuTed, was in reality a genuine case of hydrophobia,
