Dr. Mantell lived successively at Lewes, Brighton, Clapham, and London in all of which places he sustained an extensive professional practice, both in medicine and surgery, and still found time, in consequence of his great industry, to cultivate geology and the allied sciences, especially comparative anatomy, and to give many lectures on these subjects, in compliance with invitations from various towns and cities. As a lecturer, he was lucid, animated, and eloquent; and having the advantage of a noble presence, with a voice of great power and of a fine musical cadence, his appearance was eminently attractive. ...His well deserved celebrity insured on the part of the public a welcome reception to several important works, which, in the course of a few years, he wrote and published.
