From this table it will be seen that in Russia the two calibres of the 
field artillery differ from each other more than in any other country 
(excepting in England, where a gun of position has been adopted). In 
some states, on the other hand—in Germany for example—two calibres 
have been adopted differing from each other so little that it is difficult 
to understand how their co-existence is justifiable. 
Despite the fact that the calibre of the 9-pr. gun is larger than that 
of any of the foreign guns, its weight is not excessive; it is a little less 
than the 7 k French and the 10 c Swiss gun, and much less than the 
English 25-pr. gun of position. 
The weight of the light Russian 4-pr. exceeds that of the 7 C Italian 
that at 1500 metres (1640 yds.), firing at targets with double-sided shells, the light gun (German 8 C ) 
gave a mean of 60 hits per round, and the heavy gun (9 C ) 90 hits per round. If the figures in 
the above table and this quotation be true, many of the hits of the “ Eevue Militaire ” must have 
been made with small fragments, a good many of which may have been ineffective.— Eng. Tr. 
* Experiments not having been made with this piece, its shooting may be taken as equal to that 
of the Austrian 4-pr.— Author's note . 
Note by Editor of the “ Giornale d' Artiglierici e Genio ”—Without discussing the accuracy of 
the data contained in the above table, we may observe that the following are the results of practice 
with the 7'5 C Italian gun ?—
