The remaining process is exactly like that pursued before, and the 

 four results are 



Scos|V M =+0-0347, S sinfV m = -0-1830, 



S* cos iV m = -0-0479, S^ sin |V m = -0-0173. 



(o.) The Sorting of V m + V s and of V m - V s . 



These angles have to be sorted without reference to the heights, or 

 just as though all the heights were unity. Every entry is to be re- 

 garded as unity. The following example shows part of the sorting of 

 2"V W + V,, and 1 denotes a H.W., f a L.W. ; by this device H. and 

 L.W. may be sorted on the same paper. 



We may also, if it is found convenient, put on it the sorting of 

 $V m V s by adopting, say 0, to denote a H.W. and * a L.W., each 

 one of these four signs denoting simply unity.
