In the seventh volume of the Records of the Geological Survey of India, p. 142, 

 I have discussed the question as to what animal, the Sanscrit term 'jala hasti,' or 

 ■water elephant, was really applicable, as some scholars have supposed that it may 

 have applied to the now extinct Hippopotamus of the Nurbudda. Dr. Falconer's 

 mature conclusion was that that animal must have been e.xtinct long anterior to the 

 occupation of India by a Sanscrit-speaking race, but that the animal may possibly 

 have coexisted in India with its earliest human colonists. The conclusion, however, 

 to which I have eome is, that the ' jala hasti ' really applied to the Dugong.
