THE LE BOULENGE TELEMETER. 
the distance to the guns by the telemeter, and imparted to his men the 
elevation they should give on their sights (according to the distance he 
had estimated). The company at once commenced a rapid fire, lasting 
1 minute, firing 293 bullets, or 2*7 per man. 
48 took effect on the dummies , each of the latter being struck by from 
2 to 4 bullets. All the bullets were distributed perfectly uniformly. This 
alone proved, without measuring, that the telemeter had given the 
range, correctly. After having measured the distance to the dummies, 
it was exactly 936 paces, and the telemeter having given 950 paces, 
the error was only 14. 
The article in the Brussels paper concludes by recognising the 
practical utility in warfare of such a simple and portable instrument, 
the manipulation of which is so easy. Its principal use appears to be 
its power of paralyzing the efforts of the enemy at the commencement 
of the battle—that is to say, when it is possible to distinguish the 
report of the guns, and therefore to be able to measure the exact 
range with the telemeter. 
This simple instrument is being tested by all countries, and conse¬ 
quently all concerning it is well worthy of observation and study. It 
has been studied in the Spanish army, and also in the School of 
Musketry at Toledo, and we hope very soon to be able to give account 
of the results of experiments with it.
