For the suicide curve the co-efficients are : — 



= 0*3291 ; = 0*0054 ; = 0*0285 ; = 0*0097; = 0*0064. 



It will be seen that the general trend is fairly well repre- 

 sented by the sine and cosine in x only. 



In the diagram the different curves sbew the following: — 

 Curve 1 — Suicides. 



(a) The group results are shewn by firm rectangular lines. 



(b) The complete curve in sin x to sin Qx giving these group 



results is shewn by firm curved lines. 



(c) The curve given by sine and cosine of x and 2x by dotted 



curved lines.
