error, are yet not ablolutely true, becaufe they ought 
to flow with an uniform, and uninterrupted motion; 
He therefore cautioufly guards againff critical remarks 
hereupon, in the following paragraph : 
“ In this table it was thought fuffieient to ufe fuch 
cc exaCtnefs, as that thereby (in drawing the lineaments 
“ of the nautical planifphere) fenfible error mighq 
££ be avoided. He that liffeth to be more precife 
C£ may make the like table to decades, or tens of fe- 
cc conds, out of Joachimus Rheticus his Canon Mag- 
“ nus Triangulorum : notvvithftanding the geome- 
“ trician that defireth exaCt truth, cannot be fo fatisfy- 
“ ed neither; for whofe fake and further fitisfaCfion, I 
££ thought good to adjoin alfo this geometrical conceit 
££ of dividing a meridian of the nautical planifphere.’' 
“ Let the equinoctial and a meridian be drawn 
<£ upon a globe: Let the meiidian, divided into 
<£ degrees, minutes, feconds, &c. r oul upon a (freight 
££ line, beginning at the equinodial, the globe fwell-

“ ameter thereof may be always equal to the fecant

<c ous exaCfnefs of the geometrician; but for mecha-

More might be faid in favour of Wright’s chart, 
but I think it is altogether unneceflary ; if his own
