3. Much difficulty was observed, as before, in loading the Lancaster gun, 
and the Trench was again found the most easy to load; it is however right 
to mention that after the shells had been made, Commander Scott applied 
for an alteration which he said would facilitate the loading of his gun, but 
the Committee were obliged to refuse his request on account of the delay 
which it would have entailed. 
4. The Lancaster shells, with only one exception, were found on recovery 
to be split at the head; shewing apparently (as has always been suspected), 
that in that system the projectile has a great tendency to jam in the bore,
