5. The length of the jaw, — This dimension should perhaps be called 

 its depth. I mean by it a direct line from the centre of the foramen 

 magnum to the front of the incisors (B. plate 1.) In our fossil we 

 have not been able to find the trace of the foramen magnum ; but we 

 have cleared away enough, I think, to warrant our saying, that if perfect, 

 the depth of the jaw (or length as expressed above) would be quite 

 what the fossil now is. The following are the measurements : —

From the foregoing measurements, the peculiarities of this fossil 

 may I trust be elucidated. I cannot venture, with my limited know- 

 ledge of the subject, upon drawing inferences. The following passages 

 from Cuvier may perhaps be of use, to those who have not the work 

 at hand ; and apart from the earnest desire both of Mr. Torrens and 

 myself, and I am sure of every member of the Society, to see justice done 

 to so steady and active a contributor as Doctor Spilsbury, to whom the 

 Geology and Paleontology of India is so greatly indebted ; the last one 

 may serve in some degree to explain why we have thought it just to him 

 that every thing relative to this fossil, should it prove new, should be 

 placed upon record. It is no small encouragement to the pioneers in 

 every walk of Natural History, to learn, from the hand of Cuvier himself, 

 that it is to a single memoir and plate, which had been neglected for 

 seventy years in the Philosophical Transactions, that we owe the most 

 magnificent series of discoveries, which have yet illustrated the former 

 state of our globe !
