From fraction 310°-315° C., also consisting of pentacoline, the iodide of methyl- 
pentacoline was prepared. The salt was BOGEN in olive-green crystals, these,

Action of Iodide of Methyl on Hexacoline, C,,H,,N. 
A portion of fraction 325°-330° C., consisting of the base hexacoline, C,,H,,N, 
was heated in a sealed tube with iodide of methyl in the water-bath for thirty 
minutes. The iodide of methyl-hexacoline was obtained in lemon-yellow 
crystals ; these, washed with cold alcohol and dried at 100° C., gave on
