Dr. Alexander Peddie, a physician of over thirty-seven years' practice
in Edinburgh, gave, in his evidence, many remarkable instances of the
moral perversions that followed continued drinking.


RELATION BETWEEN INSANITY AND DRUNKENNESS.

Dr. John Nugent said that his experience of twenty-six years among
lunatics, led him to believe that there is a very close relation between
the results of the abuse of alcohol and insanity. The population of
