is nearly normal of type 4. This can most simply be found through 
considering the frequeney curves of the equatorial eoordinates which 
will be discussed in this paragraph. I give in table 5 the frequency 
distribution of the S’”-coordinates. lo obtain the frequency distribu- 
tion of the corresponding «''-coordinates we have to multiply by R. 
The class range is here taken to 2 R.

As to 4" and C" the dispersion is greater than in 5" and I there- 
fore here take the class range to 3 À. The results are seen in the 
following tables.
