2<j. An Examination into the fafi/oiis Acid of Winterl. By A. 

 N. Scherer. P. 43S. Winterl supposed tliat all acids owe their 

 acidity to a common principle. When they contained this principle 

 he called them living acids ; when doprlved of it, dead, ov fatuous 

 acids. When an acid con.bines witii a base it parts with its prin- 

 ciple of acidity; when it separates, it again unites with this prin- 

 ciple. When one acid expels another from a base, a double 

 decomposition takes place; th? principle of acidity separates from 

 the one acid, and unites with the other, while the base does the 

 same. Winterl asserted that if carhoiiic acid were expelled from 

 a base by heat. It would want the principle of acidhy, and would 

 not therefore exhibit the usual propertiLs of an acid. The object 

 of this paper is to prove by experiment, that this assertion is ill 

 founded.
