*The entrance of the Calcullee, or Gulcullia, River is no longer at Bogwangolab but about twelve miles lower down, between Murcha and Cutlamary; which change may have been produced by the encroachment of the Ganges.

Note by Mr. Burrow.

As a more particular account will be given hereaf ter of the manner in which these Latitudes and Longitudes were deduced, it will be sufficient here to mention, that the Meridian Altitudes of Stars from whence the Latitudes were derived, sometimes amounted to twenty or thirty, North and South, and very seldom were less than five or six, and those mostly on both sides the Meridian; so that, upon the whole, I believe very few of the foregoing Latitudes can be more than five seconds wrong, perhaps not many of them so much, as the single observations with the Sextant seldom differed from one another more than fifteen or twenty seconds, and very often not half the number. As to the Longitudes, it is possible there may in some cases be an error of two or three miles; but I can scarce believe there is any great probability of it, as the observations were made, as well as calculated, in a different and more exact manner than is generally used at present.
