 Erman's theory of the pile. Gilb. XI. 89. 



Journ. Phys. LIII. 121. 



Erman supposes, that two heterogeneous metals in con- 

 tact become electrical piincipally by induction ; that the 

 silver is positive where it touches the zinc, and negative on 

 the other side ; the zinc the reverse ; that more alternations 

 of dry metals have no further effect ; but that a communica- 

 tion with a different conducting substance, on each side, 

 favours the effect of induction ; that moist conductors in- 

 terposed, divide themselves by induction into different states 

 of electricity ; that the middle of a pile is the neutral point ; 

 and that a communication produces a discharge like that of 

 a charged jar.

For a cement take 7 parts lac, 4 resin, 2 amber, and 4 

 Venice turpentine, 12 lac, 16 resin, I amber, 3 Venice 

 turpentine, 24 pitch. Kunze. 



Sealing wax may be employed for varnishing glass, either 

 by heating the glass, or by dissolving the wax in spirits : but 

 amber varnish is better. Cavallo. 



Such a varnish makes the insulating power of the glass 

 oioxe perfect. See Machines.
