USE OF TABLES FOR A TRANSVERSE POLYCONIC PROJECTION 
FOR GENERAL MAPS OF CANADA 
In Table I will be found meridional distances in statute miles of inter- 
sections of parallels with the central meridian for every degree from the 
origin of co-ordinates, and the logarithms of the radii of the corresponding 
spherical zones. 
Tables II and Ila contain the elements for the computation of rec- 
tangular co-ordinates of every fifth degree intersection of parallels and 
meridians. 
Tables III, IV, V, and VI give the co-ordinates in inches of 5-degree 
quadrilaterals for general maps of Canada, on scales of 1 inch to 50, 60, 80, 
and 100 statute miles, respectively.
