Sending a copy of W. D. Conybeare's most recent publication; also his own Bridgewater treatise. Is grateful for his gift of luminous animals, which he has deposited in the College of Surgeons. Richard Owen has been giving the best lectures ever given. Dr. [William?] Smith is to exhibit his collection at Bulloch's museum. Is anxious to know what kind of fossil quadrupeds are to be found at the Cape.
