NOTES. 



The positions here given accord with those on the latest charts, but it is possible the 

 longitudes may be somewhat in error, and this will be decided when the telegraph 

 cable has been established. M. Fleurieu ascertained the position of the Mount of BrasU, 

 near Angra, in Terceira, to be lat. 38° 88' 37" N., long. 27° 12' 27" W. Tofiuo's result 

 was lat. 38° 38' 10'', long. 27° 14' 40", a remarkable comcidence, considering the distance 

 of time at which the observations were made. The longitude of this spot was, therefore, 

 assumed by the Spanish commander, as the meridian referred to for the points sub- 

 sequently deterntined. The summit of the Mount, as given by Captain FitzEoy, R.N., 

 is in lat. 38° 38' 35", long. 27° 12' 54". 



Captain Alexander T. E. Vidal, R.N., who re-surveyed these islands, placed the Fort 

 at Villa do Porto, in St. Mary's, in lat. 36° 56' 30", long. 25° 9' 45" W. 



The Vaeiatio« of the Compass is decreasing among the Azores, at the rate of about 2^' 

 per annum.
