CARTER BLAKE. EDITOR’S PREFACE. The Publishing Committee of the ANTHROPOLOGICAL SOCIETY have done me the honour to confide to me the task of editing Dr. Broca’s valuable little volume. This duty I have now fulfilled, and hope that the members of the Society and the general public will experience the same pleasure in reading the translation, as I received when first I perused the original. The causes which led the committee to suggest the publication of the present translation are lucidly expressed by the motto which Dr. Broca placed on his title-page. The public mind is so little acquainted with the real facts relating to the hybridity of the Races of Man, that its investigation, “_non ex vulgi opinione, sed ex sano judicio_,” is necessary to the efficient progress of our science. Such an appeal, however, necessitates that the whole subject should be again reviewed, and to attain this object the perusal of a work on similar principles to that of Dr. Broca becomes the primary requisite for future researches. It may be said, that no work which so completely investigates the whole subject of Human Hybridity has ever been published, and the Council having confirmed the recommendation of the Publishing Committee, I have endeavoured to perform my allotted task with as much prospect of success as could be anticipated amidst the pressure of numerous and laborious avocations unconnected with the Society.
