"In twenty cases various neurosal disorders had been prominent in the family and its branches, of which neuralgia, chorea, hysteria, eccentricity, mania, epilepsy and inebriety, were most common. "In some cases, a wonderful periodicity in the outbreak of these disorders was manifested. "For instance, in one family, for two generations, inebriety appeared in seven out of twelve members, after they had passed forty, and ended fatally within ten years. In another, hysteria, chorea, epilepsy and mania, with drunkenness, came on soon after puberty, and seemed to deflect to other disorders, or exhaust itself before middle life. This occurred in eight out of fourteen, extending over two generations. In another instance, the descendants of three generations, and many of the collateral branches, developed inebriety, mental eccentricities, with other disorders bordering on mania, at about thirty-five years of age. In some cases this lasted only a few years, in others a lifetime." And here let us say that in this matter of an inherited appetite there is a difference of views with some who believe that appetite is never transmitted but always acquired. This difference of view is more apparent than real. It is not the drunkard's appetite that is transmitted, but the bias or proclivity which renders the subject of such an inherited tendency more susceptible to exciting causes, and therefore in greater danger from the use of alcoholic drinks than others. Dr. N.S. Davis, in an article in the _Washingtonian_, published at Chicago, presents the opposite view of the case. The following extract from this article is well worthy to be read and considered:
