One of the first problems to be attacked from this point of view is that of the racial (i. e., heritable) effects of such poisons as alcohol. It is frequently said, for instance, that some of the effects of alcoholism are the weakened, epileptic, or feeble-minded conditions of the offspring, who are also particularly liable to disease and infection. It can hardly be said that this is as yet thoroughly demonstrated. On account of the importance of this question we might call specific attention to some recent investigations of the problem of the racial influence of alcohol. The effects of alcohol upon the individual are fairly well known, although still a matter for debate in some quarters. But this is not as important eugenically as the possible effect upon the offspring of the use and abuse of alcohol by the parents. An investigation has been carried on recently through the Galton Laboratory for National Eugenics directed toward ascertaining the precise relation between alcoholism in parents and the height, weight, general health, and intelligence of their children. It was found to be perfectly true that alcoholism and tuberculosis show a high degree of association; but considering the nondrinking members of the same community just the same high frequency of tuberculosis was found. And the presence of alcoholism among parents was found to be practically without effect upon the height and weight of their offspring. "These results are certainly startling and rather upset one's preconceived ideas, but it is perhaps a consolation that to the obvious and visible miseries of the children arising from drink, lowered intelligence and physique are not added." The difficulties surrounding investigation and the interpretation of the results of investigation in this particular field are evidenced by the fact that these results have been adversely criticised, on the one hand, because "alcoholism" was taken to mean the continued moderate use of alcohol, and on the other because "alcoholism" was taken to mean only the occasional excessive abuse of alcohol. Much of the confusion surrounding the discussion of the racial effects of alcohol grows out of the underlying confusion of statistical and individual statements. It may be left open, then, whether this result from the Galton Laboratory is clearly demonstrated and whether the basis of investigation was sufficiently broad to make the facts of general applicability.
