Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

Excerpt from Effect of Alcohol on Psycho-Physiological Functions The experiments reported in detail in the following pages give information regarding the effect of moderate amounts of ethyl alcohol upon the human organism. Since numerous workers have concerned themselves with this problem, it may seem to many readers that nothing remains to be said. However, the fact is that no solution seems to have been sufficiently substantiated to have gained general recognition. The results of the many experiments show numerous disagreements and there seems no way of harmonizing many of the contradictions. It is unsafe to discredit totally certain experiments that do not harmonize with others, for each experiment must be regarded as a sincere attempt to answer scientific inquiry, and it must be remembered that the problem is by no means a simple one. There are many known variables which exercise an influence on the results and there are doubtless as many unknown and unrecognized factors. If all the conditions of performed experiments in this field were known, doubtless unexplained contradictions would still exist. In previous alcohol experimentation, particularly with human subjects, there has been much variation in the experimental conditions. The dose employed has ranged in amount from 10 to 100] c.c. of absolute alcohol, and in concentration from pure alcohol through all the degrees of dilution with numerous liquids. The time of taking the dose and its relation to previous ingestion of food have varied, as well as the physical and mental condition of the subject. The processes measured, and the indicators of the alcohol effect used by the several investigators, have likewise differed. Furthermore, the subjects varied as to the previous taking of alcohol; some of them were habitual drinkers (a very few), others were more or less irregular in their use of alcohol, and still others were total abstainers previous to the experiments. Since control doses have rarely been used, the subjects of the experiments have, in many cases, known when the alcohol has been administered; even with control doses alcohol in any considerable quantity can generally be recognized by certain characteristic subjective sensations. Finally, the interpretation of the results is complicated by the fact that the effect of a so-called "moderate" amount of alcohol is not conspicuously large as measured by the usual methods. Taking into consideration all these variations in the experimental conditions, it would seem that sufficient complexity existed to warrant one in expecting a considerable conflict in results.
