RANGE INDICATOR DIAL. 
BY 
LIEUTENANT F. E. FREETH, R,.A. 
I beg to submit a suggestion to further simplify the Range Indicator 
Dial given in Lieut.-Colonel Williams' paper in the December Number 
of the “ Proceedings/' (Yol. XIX., No. 2, p. 55.) viz. :—• 
To have a scale of deflection at the top (which might be graduated 
exactly as that on the deflection leaf of the gun) with the letters R and 
L as shown in drawing, with a metal pointer P working along the top 
surface of the board. 
P A 
The corner A (it does not matter which right or left) cut out of the 
board and an angle slot cut to allow metal figure plates to rest in it 
for the thousands of yards.
