or else to have frankly acknowledged that in this particular field there have been great pioneers like Durkheim whose interpretations of group-psychology have largely helped to raise the subject to its present position as a branch of science.
In 1899 Dr. A. H. Keane, a poor scholar, working independently under difficulties of many kinds, published the first edition of Man, Past and Present, which at once assumed the position of one of the most comprehensive and authoritative treatises on Ethnography in the English tongue. Since it was published the mass of materials accumulated by the researches of travellers and trained ethnologists, and interpreted by a band of devoted students of this branch of science, has enormously increased.
