NOTES. 



1. The gulf and RIVER of ST. LAWRENCE, together with the Coast of New- 

 foundland, and the coasts thence to Boston and Cape Cod, are described in the British 

 American Navigator, pubhshed by the proprietor of this work. 



2. Quebec. — In the early editions of this work, the longitude of Quebec was stated to 

 be 71° 16'; " according to the observations of M. le Marquis de Lotbiniere, M. Bedard, 

 Director of the Seminary of St. LoTiis, and Captain Holland, M. Mechain computed 

 the longitude to be 71° 10', by several eclipses of Jupiter's first satelhte, observed by 

 Messrs. Lotbiniere and Holland, and the passage of Venus, which Captain Holland 

 observed in 1769. AU the observations, made at different times, have given very 

 coherent results." — Vide American Trans., vol. i., &c. 



The above passage, from " Analysis of a General Chart, &c.," Paris, 1786, shows the 

 position in which Quebec was laid down on the charts, and it agreed with that given in 

 the " Connaissance des Temps." But Quebec was afterwards exhibited considerably 

 more to the eastward. Mr. Wright, in his chart of 1807, made it 70^ 27'. The Requisite 

 Tables, of 1802, gave latitude 46° 48' 38", longitude 71° 5' 22". Colonel Bouchette, m 

 his work on Canada, 1815, gave 46° 48' 49" N., and 71° 11' W. In the years 1819, 1820, 

 and 1821, the officers of H.M.S. Newcastle, provided with four chronometers, made many 

 observations in the river, and these observations may be judged of by the longitude in 

 which they placed Quebec for three successive years, assuming Hahfax as in 63° 33' 40"; 

 July 16th, 1819, 71° 12' 48" ; June 19th, 1820, 71° 13' 14" ; July 5th, 1821, 71° 12' 25". 

 The greatest difference is 49", and the mean of the whole is 1" farther West than tbe 

 longitude given in 1819. 



From these and other observations combined, the late Mr. Purdy placed Quebec in 

 longitude 71° 13', in the charts, &c., which he constructed. 



When the charts of Captain H. W. Bayfield were pubhshed in 1837, they were based
