1 The ranges given for this gun cannot he correct, giving as they do equal increments of 
range for equal increments of elevation. 
The ranges of guns at the “ end of the 18th Century/ 5 given in the 
foregoing table, are taken from a MS. note book belonging to Major 
Ery, r.f.p., R.A., and dated 1806. When he copied these ranges, they had 
been in use for some years* 
[Since making the foregoing table, Brigadier-General Lefroy, R.A., has told me that there still 
exists in the R.A. Library, Woolwich, a number of range tables by General Borgard, the first 
Colonel of the Regiment, dating back to the middle of the last century.]
