In the Annual Beport, 1892-93, p. 333, No. 7, Yol. XX., E.A.I. “ Proceedings,” 
the inscription mentioned by Major-General E. Markham should read 
“ Under this stone 
lies the 
Eight Arm 
of 
Lt.-Colonel C. S. Henry, 
E.H.A. 
17th August, 1855.” 
In the recent Cambridge Mathematical Tripos Mr. E. T. Dixon was placed 17th 
Wrangler. He only resigned his subaltern’s jacket in D/A., B.H.A., in May, 
1888. His high place on the list is the more praiseworthy as he is at a disad¬ 
vantage in the matter of age compared to the mass of competitors. 
A correspondent gives this rough rule:— 
When carrying out practice over sea ranges, the following has been found a 
handy method of improvising a safety triangle to determine whether ships, &c., 
are within an angle of 7^° with a line from the battery to the target, and if it is 
consequently unsafe to tire. Close the first three fingers of the right hand, hold 
the thumb and little finger upright, separated by the clenched fingers, and extend 
the arm at full length. Align first the top of the thumb, then the top of the 
little finger with the target, and any object seen inside the little finger on the left 
of the target, or inside the thumb on the right of the target is within 7^°, and in 
the dangerous zone. This will be found approximately correct for most people, 
as the distance from the eye to the top of the fingers, arm at full length, is eight 
times the distance between the top of the thumb and the little finger, and tangent 
7i° is nearly. 
It should be tested by finding with the D.E.F., using the Vernier, two objects 
7|° apart, and aligning on them. The proper position of the fingers can then 
be readily seen. 
“ The Army Book for the British Empire,” published by authority, will make its 
appearance at an early date. The book will, to a large extent, be descriptive of 
the system on which the army has been built up since 1872, in which year, it 
will be remembered, Mr. Cardwell, who was then Minister, introduced such 
radical but necessary changes. 
It is being edited by Lieut.-General W. LI. Goodenough, c.b., and Lieut.- 
Colonel J. C. Dalton, who have obtained the co-operation of various contributors, 
all experts in the special subjects they treat of. 
The book will be in four parts :—■ 
I. The army system, 
II. The components of the army, 
III. The army in India and the Colonies, 
IV. The army in war, 
and will be illustrated with two portraits and with maps.
