ELECTRICAL RELATIONS. 139 



chapter on galvanism. Electricity also resolves salts 

 into the bases and acids which compose them. The 

 acid goes to the positive pole, and is, therefore, elec- 

 tro-negative. The base goes to the negative pole, and 

 is, therefore, electro-positive.* 



* The laws of combination, and other subjects which belong to 

 chemical philosophy, are further considered in the chapter on Salts, 

 in the introduction to Organic Chemistry, and in the Appendix. Ad- 

 ditional remarks on the atomic theory adopted in the text, are also 

 given in the Appendix.
