" It is not to be denied that there are bodies having the number of 

 atoms occurring in sugar, and yet not tasting sweet. Still, the corre- 

 spondence in constitution among so many bodies, containing such a 

 variety of elements, and all having the common property of sweet- 

 ness, is an interesting fact. Do sweet bodies owe their sweetness to a 

 common arrangement of their ultimate particles 7 or, in other words. 

 Have sweet bodies a co^nmon forin ? 



" It may further be remarked, that the constitution of acids, as sug- 

 gested by Davy in relation to inorganic acids, and applied by Liebig 

 to organic acids, permits them to be written in a common formula 

 = H -|- .r ; X representing all that part of the isolated acid not re- 

 placed by metal in neutralization. A few examples follow. 



^' Sour Bodies.
