PROJECTION OF A
POLYGON 4" X 7"

This shows how the proportions of a falling group of notes can fit into a progression by cubes, through a simple projection technique. The only angles at which acceleration could take place are those indicated according to P.D.
Ouspensy's theories. Re is 36 degrees; Ti is forty degrees; etc., according to the number of sides of a polygon. Five/six is the ratio for MIb; the number six indicates the number of sides; the angle thus would be 60 degrees.
