 as foon as they are obtained, provided they fliall feem de-

 fubjo-ining, that when a metallic communication was formed; 

 in the dark between the ends of a powerful Galvanic column^ 

 »n appearance of light refembling a fmall eledtric fpark wa$ 

 d'ifiiniSlly perceived at the moment of contaft : that the 

 copper and zinc,' when applied to each other, difcover a 

 flroiig Galvanic power j yet plates of brafs had no fuch 

 power, even when piled with moiften€d alumine : that alu- 

 jnine appealed to be more Galvanic viben moidened with 

 b-rinc, than when moiftened with water ; that pailel)oard 

 v^as decidedly more Galvanic when nioiflened with weak 

 folphuric acid, than when moiftened either with water of 

 brin-" ; and that by inclofing a powerful Galvanic column 

 in a box, armed in the manner of a magnet, I have con- 

 firiifted a kind of Galvanic machine, which is eafily carried 

 &ODI place to place, which is extremely convenient in many 

 experiments, and which has enabled me to explain the 

 powers of the torpedo more clearly, I believe, than ha* 

 Jiitherto been done. 



I have the honour to be, with great efteem. 

 Dear Sir, 

 Your much obliged fervant.
