This phase of thought in its extreme form will no doubt pass away like the former, but these oscillations should teach us at least this one lesson that no dictatorial authority should ever stop the progress of science, and that nothing is so dangerous as a belief in our own infallibility.
If we turn away from the Asiatic continent, the original home of the Aryan, the Semitic, and the Turanian languages, we find that in Africa, too, a comparative study of dialects has clearly proved a concentration of African speech, the results of which may be seen in the uniform Bantu dialects, (Kafir, Setchuâna, Damara, Otyiherero, Angola, Kongo, Kisuahéli, etc.), spoken from the equator to the Keiskamma1. North of this body of Bântu or Kafir speech, we have an independent settlement of Semitic speech in the Berber and the Galla dialects; south of it we have only the Hottentot and Bushman tongues, which are now declared by Dr. Th.
