The pure base forms a white amorphous powder, almost insoluble in water and ether, 
very soluble in alcohol. Its salts, like those of other bases derived from narcotine, are, 
as far as they have been prepared, amorphous. The base may be called dimethyl- 
normal-narcotine, or, shorter, dimethyl-nornarcotine. The rational formula of this base 
is either

Further experiments will show which is the correct one : in the annexed Table the 
properties and reactions of the narcotine bases are given side by side. Neither of the 
above bases have any marked physiological effects ; for in working with them, as well as 
in taking grain-doses, no ill effects have been observed. It is worthy of notice that the 
taste of the chlorides varies so markedly by the replacement of one atom of methyl by 
one of hydrogen.
