in supplying highly specialized pedigrees of the particular trait in which they were interested. In certain limited but valuable fields, they thus made possible by the questionnaire and correspondence method a close approach to field-worker accuracy in gathering first-hand data on human heredity. Since the establishment of the Eugenics Record Office hundreds of inquiries of this sort have been answered. But on account of the time and labor involved in abstracting and analyzing the data and in answering the particular questions, the practice has been discouraged. However, if a competent clinic were organized for handling such problems, and if it were generally known that such a clinic were available, doubtless a great number of cases with accompanying data on the family distribution of certain specific subject-traits would be offered to the clinic each year.
