the reduction of weight placed Mr Lancaster at a disadvantage in respect 
to the length of bearing of his shot, which was reduced from 8 to 7 in. 
15. The Committee having determined to give the detailed records in an 
appendix, are anxious not to confuse the body of the report by the introduc¬ 
tion of more figures than are necessary; they, therefore, record, in the first 
of the following tables, only the mean range, the mean deviation from that 
mean range, and the reduced deflection. This last term has always been 
used in tables of this nature, but it is not self-explanatory, and it is as well 
to state that it means the mean lateral deviation from the mean line of fire. 
The Committee wish also to explain that the table headed “ general means 33 
represents no actual result, but it is introduced to collect into one line the 
aggregate results of the practice with the three charges of powder at the 
three elevations.
