The Hydkographic Sur- 

 veys of the Western Coasts 

 of France, made by the French 

 Engmeers, under the direc- 

 tion of M. Beautemps Beau- 

 pre, with later observations. 



Remarks. 



It is to be remarked, that the 

 longitudes, as given in the Con- 

 naissaiice des Temps, compared 

 with those in the Charts of the 

 JPiloie Froiicais, constructed be- 

 tween 1816 and 1827, under the 

 direction of M. l-JeautempsBeau- 

 pre, showed adifference amount- 

 ing to, at the least, 51-5", the 

 former Survey being so much 

 less, which was occasioned by 

 the later determination of the 

 geographical position of Crozon, 

 near Brest, as explained in the 

 note. The longitudes given in 

 the Table are corrected.
