Charles Cooper King, The Story of the British Army
“ The general direction of the improvement in firearms is to lessen the size of the bore and increase the flatness of the trajectory. Thus the high-angled fire of the Snider, converted from the muzzle-loading Enfield, was changed for the Martini-Henry, in every way a more deadly weapon, and this, as has been already remarked, has given way to an even smaller bored rifle. And with the increased rapidity of fire and the larger number of rounds of the lighter ammunition that can be carried, the bayonet, that was lengthened in 1878, was reduced to its present dimensions. ”
