Researches respecting the radical of Benzoic Acid. 285 
Bz=Benzéylic acid. 
BzH=Bitter almond oil. 
BzCl=Chlorobenzoyl. 
B’z or BzS=Sulphuret of benzoyl.* 
Bz+2NH?= Ammoniuret of benzoyl, (benzoyl ammonia.) 
Ifwe put Amid=NH?, we have 
Bz+NH2?=Benzamid or bitter benzoylamid. 
C+NH? =Oxamid. 
K + NH?=Potassiumamid, (Berzelius’ Chemistry, I. 794.) 
N+NH2=Sodium amid. 
If we further place oil of wine, which I propose to call etherin, 
C4H*=E, we find 
E+ 23£=Alcohol. 
E+ 3=Ether. 
E+ #-€7 =Muriatic ether. 
E+3¢ E=Niiric ether. 
E + Bz EE =Benzéylic ether. 
ES+ 3¢S=Sulphovinie acid according to Hennel and Serullas. 
E+2 3£S=Sulphovinic acid according to Wohler and Leibig. 
2ES+  €=Sulphuric oil of wine. 
E+ A¥£=<Acetic ether. 
2E+ A¥~E=(Pyroacetic spirit?) (Brenzessiggeist. German.) 
E+ 2P1€7=Zeise’s ethereal salt. 
E+ 2Pt=Ethereal oxid of Platinum. 
E+ 2Pt=Ether platinum. 
Suppose by way of experiment, there is an oxid of etherine=E, 
then E+ FE=Ligneous spirit. (Aolzspiritus. German.) 
2+ 34-=Acetal or Doebereiner’s new oxy-ether. 
From these two last formulas, we perceive that acetal has the same 
relation to ligneous spirit, that pyroacetic spirit bears to acetic ether. 
But I think it necessary to insist, that such formulas be employed 
only when the ideas they express, are advanced in some measure to 
confirm truths, else they would lead to a Babylonian confusion. 
* It will be of great interest, to ascertain the behavior of this body to sulphu- 
rets.—B. 
t According to the results of analyses of both bodies, which I sent by letter to Ber- 
zelius, and which will appear in one of the succeeding numbers of this Journal.—J. L.
