VIU PREFACE. 



composed of memoirs and observations, for the most 

 part written subsequently to his return to Europe. 



Many of the memoirs in the first volume have been 

 already published, but in journals which are accessible 

 to few scientific men in Enirland or on the Continent. 

 Others, though written many years ago, are now pub- 

 lished for the first time. The researches on the Fossil 

 Fauna of the Sewalik Hills were conducted by Dr. Fal- 

 coner jointly with his friend Captain (now Sir Proby 

 T.) Cautley, and all the new species were announced 

 in their joint names. Some of the published memoirs 

 appeared in the names of both, and others in the name of 

 one only of these observers ; but all have been here col- 

 lected, so as to bring together as complete an account of 

 the Sewalik Fossils as is now possible. With the same 

 object, several short notes by Messrs. Baker and Durand* 

 have likewise been inserted. Most of the papers have 

 also been enriched by appendices, in the form of extracts 

 from Dr. Falconer's Note-books and correspondence, or 

 from his published descriptions of the Sewalik Fossils in 

 the Catalogue of the Asiatic Society's Museum in Cal- 

 cutta. The first volume likewise comprises an Index to" 

 all the published plates of the ' Fauna Antiqua Siva- 

 lensis,' compiled by the Editor from entries in the 

 author's Note-books, from references to the figures in 

 his published memoirs, and from labels in his hand- 

 writing on the figured specimens now in the Palteonto- 

 logical Gallery of the British Museum. For assistance 

 in identifying these specimens the Editor is under obli- 

 gations to Mr. W. Davies of the British Museum. In 

 the first volume will also be found a Report by Dr. 



* Now General Baker, and General Sir Henry M. Durand, K.S.I.
