published. 
Phe <add iodide was resolved with oe aid of silver 
salt of Armstron owry’s bromocamphor grants 
Phen ve vio remmrrl iodide was resolve with ~t it of 
silver salts of Reychler’s ee anid" Anmst ong and Lowry's 
bromocamphorsulphonic acids. In t oe © camphorsulphonates, 
both dB dA and 1B dA salts have Se obi con a pure condition. 
It is also found in the case of the 8 bartip herein wcabead: ‘hut ¢ the two 
salts form solid solutions one in the other, when. their ee 
corresponds to 46 per cent dB dA and 54 per cent 1B dA compon 
Phen oo iodide was resolved with the aid “of ‘silver 
salt of d-cam oe “sulphonic acid. 
d © effect of consti tation on the optical rotatory power of these 
nitrogen base is discussed. is found that Guye’s expression connecting 
mass and r. tatory power does ea hold, but further judgment is reserved 
till more area in this series, which is in progress, is completed.
