little, comparatively speaking, a vessel will appear to be foreshortened 
when thus turned to the glancing angle of service projectiles. Here 
however I am getting beyond my province, so I will now come to our 
siege and field equipments, considering the former to consist of 64 and 
40-pr. B.L. guns, and the latter of 20, 12, and 9-pr. B.L. and 9-pr. 
M.L. guns. The 7-inch B.L. is rather hard to classify; I need not 
however notice it beyond mentioning that it fires the same projectiles 
as the 64-pr. Besides these there is a 16-pr. proposed as a heavy field 
gun, and there is also our 7-pr. mountain equipment, all firing— 
Common shell, | Segment shell, 
Boxer shrapnel shell, | Case shot, 
except the 9 and 7-pr. M.L., which have no segment shell, and the 
20-pr., which for some reason has as yet no shrapnel. The 40 and 
20-pr. still have solid shot also, and the 7-pr. a double shell. 
The time fuzes for service generally are the 5 secs, and 9 secs. M.L.O. 
fuzes for the muzzle-loaders, except the 7-pr., which has a special gauge 
fuze hole and set of fuzes which I trust are shortly to be abolished.* The 
* Abolition since ordered to be carried out.
