copy of a signal book dated 1756, in which the above instructions are referred to.

It is in the United Service Institution (_Register No._ 234).

At the end it contains a memorandum of a new article by which Hawke modified the established method of attack, and for the first time introduced the principle of each ship steering for her opposite in the enemy's line.

It is printed below, and as will be seen was to be substituted for 'Articles V.and VI.

of the Additional Fighting Instructions by Day' then in force, which correspond to Articles XV.
