In conclusion the author points out the possibility of obtaining triatomic, 
tetratomic and pentatomic bases, either by the action of ammonia upon 
more highly brominated bromo-ethyl bases or by the same action upon 
bases containing two, three or four equivalents of bromo-ethyl. Thus we 
might have the reactions indicated by the equations

Hofmann has already obtained a series of triatomic bases, of which 
diethyientriamin may bé regarded as especially worthy of notice. The 
base has the formula
