Ascribes the increase of conducting power to moisture 

 rather than to cold. 



Kinnersley's experiments. Ph. tr. 1763. 84. 

 fKinnersley on the conducting power of 

 charcoal. Ph. tr. 1773. 38. 



A line drawn by a black lead pencil conducts.

 different circumstances. A. P. 1766.451. 



Priestley on the conducting power of char- 

 coal. Ph. tr. 1770. 211. 

 Cotte. A. P. 1772. i.H. 16. 



Snow serves as a conductor in storms. 



Henley's experiments. Ph. tr. 1774. 389. 



Shows that vapour is a conductor, and that an imperfect 

 ♦acuum conducts. 



Henley on the impermeability of glass. Ph. 



tr. 1778. 1049. 

 Cavendish. Ph.tr. 1776. 



Iron wire conducts 400 million times better than pure 

 water; sea water, with one thirtieth of salt, loo times 

 better ; a saturated solution of salt 720 times better.

Berl. 1777.25. 

 Achard on the analogy of conductors of 



heat and of electricity. A. Berl. 1779. 27. 



Roz. XXII. 245. 



With an instrument for measuring the conducting power. 



Achard on the distinction of conductors and 

 electrics. Roz. XV. 117. 



Achard Schriften. 246. 



Bergman on the conducting power of water. 



Roz. XIV. 192. 

 Cavallo. Ph. tr. 1783. 495. 



Pith balls electrified did not diverge in the vacuum of an 

 air pump, whether much or little electricity was commu- 

 nicated to tliem. Perhaps from the perfection of the con- 

 ductor. 



Cavallo on a vacuum. Electr. ed. 4. part 4.

 Lavoisier and Laplace on the electricity 



absorbed by vapours. A. P. 1781. 292. 



H. 6. 

 Coulomb on the loss of electricity in a given 



time. A. P. 1785. 612. 



Morgan on a vacuum. Ph. tr. 1785. 272. 



When the mercury has been boiled for some hours in a 

 gage, neither light nor charge can be procured in it. Air 

 conducts best when the light streaming through it is 

 bluish violet. Acids conduct better than water, and hot 

 water than cold. 



Vassalli and Zimmerman's experiments on 

 water and ice. Soc. Ital. IV. 264. 



Eandi. M. Tur, 1790. V. 7. 



Says that light may be seen in the dark, even when the 

 vacuum is perfect. But it may be said that some mercurial 

 vapour is present. 

 Volta on the use of the electrometer in hy- 



grometry. Soc. Ital. V. 551. 

 Volta. Gilb. XIV. 257. 



Says that wire conducts a million times better than water. 

 Repeats some of Cavendish's experiments.

on the emission of the electric fluid. B.
