In the remarks introductory to the preceding part of this essay, I 

 adverted to the importance, for sound reasoning in geology, that 



* For the abstract of tliis communication already published, see Quart. 

 Journ. Geol. Soc, vol. xiv. p. 81. Part 1 was published in full, with ilhistrative 

 plates, in vol. xiii. p. 307. This part (unfortunately imperfect, as it is wanting, 

 at least, in the description of Elephas antiquus, and in a portion of that of E. 

 prinvigenius, neither of winch desiderata appear to have ever been written) is 

 now published posthumously without illustrations ; but should the figures or spe- 

 cimens designed to illustrate it be satisfactorily determined, the illustrations will 

 be published in a future number of the Journal. The Assistant-Secretary has 

 received much invaluable assistance, in editing this paper, from G. Busk, Esq., 

 F.E.S., F.G.S., especially in the determination of specimens and figures re- 

 ferred to, but the numbers of which were not filled in by the author.
