when I observed the polar star at the south end of the base line.

It was discovered, that at Perumbauk hill, there had been an error in reading off the south end of the base, most probably of 10" from the micrometers, as all the angles which had a reference to that point, exceeded what they ought to have been by ten or twelve seconds. In consequence of this disagreement, I chose to take the supplemental angle in the second and fourth triangles, after the other angles had been corrected. The distance of the north end of the base from Perumbauk, as determined in the second triangle, being taken as a base in the third triangle, wherein the three angles have been observed to determine the distance from Perumbauk to the Mount, and from the north end of the base to the Mount, it appears that the latter distance comes out within 0,4 of a foot to what had been brought by the first triangle; and that the distance from the south end of the base to Perumbauk hill, derived from the second and fourth triangles, differ only, 14 of a foot. The distance from the Mount to Perumbauk being that from which all the operations are to commence, I wished to be as particular as possible in determining it, and the results from the third and fourth triangles make it 43495,4 and 43495,5, differing only onetenth of a foot.

174 AN ACCOUNT OF A NEW SPECIES OF DELPHINUS.

is like the lean of beef in colour, nor has it any difagreeable smell; yet, so far as I can learn, the natives never eat it.

In the stomach were found only some grains of paddy, (rice in the husk,) a few minute fragrants of shells, and many living active Afcarides.* Notwithstanding the contents of the stomach of this individual, there is no doubt of the animal being piscivorous.

* These (Afcaris Delphini they may be called) are about two inches long, of a pale, almost white colour, tapering little, but equally towards each end: the mouth is situate in the center of three tubercles; over the anus is a small pointed hornlet on the obtufe tail of the animal.
