In a general form this second/method may be expressed by the 

 equation 



' l Br 2 + 2rc H, N=[R n H (271+4) N (n+1) ]<+i>Br (fH .,) + n-l ([H 4 N]Br), 

 which represents the formation of the first term in each series of a 

 succession of basic groups of increasing atomicity. 



The simplest case involved in this equation is the formation of the 

 first term of a series of diammonium-compounds. When n=l, the 

 above equation assumes the simple form 



R ii Br 3 +2H 3 N=[RH N 2 ] ii Br 2 ; 



and if R ii = (C 2 H 4 ) ii , we obtain in this manner the dibromide of 

 ethylene-diammonium
