The great prevalence of drunkenness among the upper classes two centuries ago can hardly have been bred out in the intervening six or seven generations, and it is also a difficult fact for Mr. Reid that drunkenness has increased in France. In most of the cases cited by Mr. Reid a complex of operating forces could be stated in which the appearance of fermented liquors is only one factor, and a tangle of consequent changes in which a gradually increasing insensibility to the charms of intoxication was only one thread.
