principles and documents be duly confidered; if almoft 
general practice and experience for a century and an 
half part can have any weight; and, if the concur- 
rent teftimony and authority of fo many eminent 
mathematicians who have handled this fubjedt fince 
his time, and fome of them in a quite different 
method, can have any poife in the fcale of reafon. 
I have carefully endeavoured not tomiftake the true 
enfe and meaning of Mr. Weft’s proportion in any 
part thereof; if I have not, I cannot pronounce what 
kind of chart may be formed from his tangent line 
being made the line of latitudes, or that meridian line 
whereupon the tangents are to determine the fedions 
or their iefpedtive parallels: I fhall only obferve, that, 
ii the meridians be right lines, and parallel to each 
other, the rhumbs muff be right lines alfo; but by this 
tangential projection, tbefe will be defleded from their 
true bearings, or make the angles of the courfes too 
great unlefs fome expedient be devifed to accommo- 
date this error; and if the rhumbs be not right lines 
fuch chart will then be embarraffed with more diffi- 
culties in pra&ice than Mr. Wright’s.
