In the Journal for 1879 I was permitted to insert a notice of the scholars who have contributed to the extension of our knowledge of the Languages of British India during the last thirty years; and upon the occasion of its being read at one of the Society's meetings, considerable interest was shown in the subject. I venture now to intrude upon the Society with a kindred notice upon those great scholars who have devoted their talents, and in many cases their lives, to enlarging our knowledge of the Languages of Africa.
