Plate II. The Calan y of the B-stars as seen from the axis of Z. 
This plate gives the projection of the Galaxy of the Bid on 
the XY-plane (7 the fundamental plane of the Milky Way) according to 
the catalogue in table 16. The coordinates are given only to the whole 
Siriometer. Consequently there are 31 stars having the same projected 
coordinates x, y. Each one of these stars is on the diagram indicated 
by a single dot.
