344 [Jan. 8, 



Zoned polar summit : 



4*^14=1, with the same zones. 

 Zoned non-polar or monozone face : 



3 m '24=i, z={i,3, o 2 }. 



Zoned summit : 



3 m 24=l, Z={3, 1, Q 2 }. 



Table D. 

 Zonal edge : 



(33).>13=1, Z={3,1,0 2 }. 



Episonal edge : 



)3=l, z={l,3,0 2 }. 



Registration of the 5-edron 6-acron. 



Table A. 



One 3-zoned monarchaxine, having an amphiedral principal axis 

 terminated by triangles., and edrogrammic secondary axes. Its two 

 zones are those next written. 



Table B. 

 J r anal zoned polar face : 



(3)3^34= 1, Z= {2.1, 2.1 p +l p , Q P , 

 Z'=3{..1 P ,0,}. 



Table C. 

 Polar coned faces : 



1, Z={2, l + 2, 0, 



Table D. 

 Polar zoned edge : 



(44)^03=1, z={2.i, 1^+2.1, Op, o^.i}, 



Z'={.. 1^ + 2.1, Op, 02-1}. 

 Epizonal edge : 



(34V3=l, Z={2, 3, 0, 02}. 



We have not here registered the summits of the 5-edron C-acron, 

 as they are merely the reciprocals of the faces of the 6-edron 5-acron. 

 For a like reason we shall avoid the trouble of registering hereafter 

 any summits.
