FIG. 195 The planisphere (Part II) 



To put the planisphere together paste Fig. 194 smoothly on a thin card and cut it 

 out. Do the same for Fig. 195, but after it is pasted on the card, with a sharp pen- 

 knife, cut out the ellipse from the card. Cut a second card circle the size of the circle 

 of Fig. 195 and mark its center. Run a pin through the center of Fig. 194 and through 

 the center of this circular card placed below Fig. 194. Lay Fig. 195 on Fig. 194, its 

 circular edge just inside the strip bearing the names of the months. Bend the four flaps 

 on Fig. 195 over the edge of Fig. 194 and paste them to the circular card below. Bend 

 the pin so that its end will lie down against the circular card back and hold it in place 

 by a piece of paper pasted over it.
