[underscore] 4. Eugenical Research and Clinical Service [end underscore] A definite and accurate human pedigree showing the family distribution of a particular human quality - whether physical, mental or spiritual - added permanently to the stock of data of the Eugenics Record Office, is thus made available as further evidence for analysis in determining more exactly the rules by which Nature governs the inheritance of the given trait. Long experience has demonstrated to the Eugenics Record Office that the most valuable pedigrees of human traits are secured, in greater abundance and at fractional monetary cost, by the practice of the Eugenics Record Office aiding the individual who prepares the record in the genetic analysis thereof and in pledging permanency and privacy in the archives. The work of the proposed clinic, in thus securing first-hand records of family traits, would promote the primary research functions of the Eugenics Record Office, besides serving the practical use as a clinic. [underscore] Note on the Experience in the Clinical Field of Human Heredity.[end underscore] As a matter of fact one of the unavoidable functions of the Eugenics Record Office in the past has been to serve in a limited manner as a clinic of human heredity. Since the establishment of the Eugenics Record Office many persons, not knowing where else to turn, have written to this office a statement of their problems in human heredity and have asked for an analysis and interpretation of the facts. Such inquiries thus furnished the office with valuable first-hand data, the cost of which if secured by the field-worker method, would constitute an expense which could not have been borne directly by the office. Such inquiries often proved to be valuable collaborators [end]
