In considering this question, we must bear in mind that intemperance is only a relative term; for in the early part of the century we read of our ancestors indulging in a bottle of port wine to each individual, without, it seems, incurring the charge of drunkenness. There cannot be a doubt, however, that the habitual use of alcohol, without being carried to the extent of actual intoxication, is calculated to cause a low and feeble condition of the body, and thus conduce to the production of idiocy in the offspring; for we may fairly assume that what too severely tries the nervous system in one generation will appear in their descendants.[7] Without, therefore, exaggerating the influence of alcohol on the genesis of idiocy, I think I shall not be deviating from the path of strict scientific accuracy, if I say that over indulgence in alcoholic beverages is calculated to produce a low state of vitality, and a degeneration of nerve tissue which may culminate in the development of idiocy in subsequent generations.[8] Just now that the attention of the Legislature is being prominently called to the treatment of habitual drunkards, it cannot be too widely known that their innocent offspring are but too frequently the victims of the brutish excesses of their parents, who, a few years ago, were well described by the then Secretary of State for the Home Department, when receiving a deputation on the subject, as not quite criminals nor quite lunatics, although nearly approaching both classes in many cases. The above statistics fully corroborate the pertinency of Lord Cross's remarks. I do not allude to these facts with the view of casting any reflection upon the poor, honest, and temperate East Anglian labourer, who may be afflicted with the calamity of having an idiot child; but I merely mention them in order that they may serve as an additional caution against habits of intemperance, and may strengthen the hands of that noble band of philanthropists who are endeavouring to check the torrent of this hideous vice so prevalent in the present day. _Consanguine Marriages._ There is no point connected with the causation of idiocy that has given rise to so much controversy as the marriage of near relations; formerly one of the most popular notions was that consanguineous marriages were among the most common causes of idiocy, whereas the researches of later observers have tended to modify, to a considerable extent, this sweeping assertion. Different observers have furnished different results, as to the proportion of idiots found to be the offspring of consanguine marriages; thus Dr. Grabham's statistics give the proportion as about 2 per cent., Dr. Langdon Down's rather more than 5 per cent., and Dr. Shuttleworth's less than 5 per cent. The statistics of the Eastern Counties' Asylum, kindly supplied to me by Mr. Turner, the Resident Superintendent, show that about 6·5 per cent. were the offspring of cousins.
