On some Fossil Remains of Anoplotherium and Giraffe, from the Se- 

 walik Hills, in the North of India. By H. Falconer, M.D., 

 F.G.S., and Capt. P. T. Cautley, of the Bengal Artillery, 

 F.G.S. 



In continuation of their former researches on the fossil remains of 

 the Sewalik Hills, the authors, in their present communication, es- 

 tablish, on the clear evidence of anatomical comparison, certain dis- 

 coveries which, in previous publications, they had either merely an- 

 nounced, or had supported by proofs professedly left incomplete. 

 They now demonstrate that there occur in the remarkable tertiary 

 deposits of the Sewalik range, together with the osseous remains of 

 various other vertebrate animals, bones belonging to the two genera, 

 Anoplotherium and Giraffe : the former genus determined by Cuvier 

 from parts of skeletons dug out from the gypsum beds of Paris ; the 

 latter genus known only as one of man's contemporaries, until in 

 the year 1838, the authors gave reason for believing its occurrence 

 in the fossil state. 



The specimens now figured and described form part of the collec- 

 tion which was made by the authors on the spot, and is now depo- 

 sited in the British Museum. They were found, together with re- 

 mains of Sivatherium, Camel, Antelope, Crocodile, and other animals, 

 in the Sewalik range to the west of the river Jumna. 



The bones are found imbedded either in clay or in sandstone. 

 When clay is the matrix, they remain white ; and except in being 

 deprived more or less completely of their animal matter, they have 

 undergone little alteration. The bones in this state the authors have 

 eleswhere designated as the "soft fossil." When sandstone is the 

 matrix, the animal matter has completely disappeared, and the bone 

 is thoroughly mineralized and rendered nearly crystalline by the infil- 

 tration of siliceous or ferruginous matter, and acquires a correspond- 

 ing hardness, or tinge of iron, with increased specific gravity. The 

 matrix in contact with the bone is rendered compact and crystalline 

 in texture. The remains in this state have been designated by the 

 authors as the " hard fossil."
