Q = + 31°.91 
The antiapex lies in the square £,, in the constellation Canis 
major, and has the coordinates 
The angle between the apex and the anticentre amounts to 28.75. 
The angle between the vertex and the negative Y-axis amounts to 
24°.96. 
I give for the present these numbers without further commen- 
taries. 
20. Squares and constellations. The squares are often more 
convenient than the constellations to indicate the rough place of cele- 
stial object, and I give therefore here a short description of the rela- 
tion between these divisions of the sky. I put in brackets, | |. those 
constellations which are only to an inconsiderable degree included in 
a certain square, and in parentheses, ( ), the brightest stars of a con- 
stellation, contained in a square.
