Many of the pieces used at the siege of Baza, in 1486, are still to be seen in that city, and also the cannon balls then in use.

Some of the latter are fourteen inches in diameter, and weigh one hundred and seventy-five pounds.

The length of the cannon was about twelve feet.

These dimensions are a proof of a slight improvement in this branch of military science, which was, nevertheless, still in its infancy.

The awkwardness of artillery at this period may be judged of by its slowness of fire.
