342 Horner's Geological Address, 



found in the Tertiary formations of the Sewalik Mountains, 

 at the southern foot of the Himalayas, between the Sutlej 

 and the Ganges ; discoveries deemed so important, that the 

 Council, at the following anniversary, awarded a Wollaston 

 Medal to each of these gentlemen. Besides the paper by 

 Captain Cautley, published in the fifth volume of our " Trans- 

 actions," numerous details respecting these discoveries are 

 contained in the '* Asiatic Researches," and in the " Journal 

 of the Asiatic Society of Bengal." A magnificent donation 

 of these remains, contained in more than two hundred chests, 

 was made by Captain Cautley to the British Museum, and a 

 work of immense labour and research has been undertaken by 

 Dr Falconer, to describe, in conjunction with his friend, now 

 Major Cautley, these very interesting remains. Her Majes- 

 ty's Government and the Directors of the East India Com- 

 pany have supplied funds in aid of the successful progress 

 of the work. The first part has just appeared ; it bears the 

 title of " Fauna Antigua Sivalensis,^^ and consists of twelve 

 folio plates, and sixty-four pages of octavo letter-press. No- 

 thing has ever appeared in lithography in this country at all 

 comparable to these plates ; and as regards the representa- 

 tions of minute osseous texture by Mr Ford, they are per- 

 haps the most perfect that have yet been produced in any 

 country. 



The work has commenced with the Elephant group, in 

 which, they say, " is most signally displayed the numerical 

 richness of forms which characterizes the Fossil Fauna of In- 

 dia," and the first chapter relates to the Proboscidea — Ele- 

 phant and Mastodon. The authors have not restricted them- 

 selves to a description of the Sewalik fossil forms, but they 

 propose to trace the affinities, and institute an arrangement 

 of all the well-determined species in the family. They give 

 a brief historical sketch of the leading opinions which have 

 been entertained by palaeontologists respecting the relations 

 of the Mastodon and the Elephant to each other, and of the 

 successive steps in the discovery of new forms which have 

 led to the modifications of these opinions. They state, that 

 the results to which they themselves have been conducted, 

 lead them to differ on certain points from the opinions most
