342 TABLE OF LATITUDES AND LONGITUDES. 



Note by Mr. Burrow. 



Asa more particular account will be given hereaf- 

 ter of the manner in which these Latitudes and Lon- 

 gitudes were deduced, it will be sufficient here to 

 mention, that the Meridian Altitudes of Stars from 

 whence the Latitudes were derived, sometimes a- 

 mounted to twenty or thirty, North ana 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 pos- 

 sible 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.
