and X.for bringing a flying enemy to action.
With these internal inferences to corroborate the direct evidence of our documents the conclusion is clear--that during the War of the Austrian Succession the new system initiated by Vernon was developed by Anson as a consequence of Mathews's miserable action off Toulon in 1744, and that its first fruits were gathered in the brilliant successes of Hawke and Anson himself in 1747.
Though no complete set later than those used by Boscawen is known to exist, we may be certain from various indications that they continued to be issued as affording a means of giving elasticity to tactics, and that they were constantly issued in changing form.

Thus Rodney, in his report after the action off Martinique in April 1780, says, 'I made the signal for every ship to bear down and steer for her opposite in the enemy's line, agreeable to the twenty-first article of the Additional Instructions.' Again in a MS.

signal book in the Admiralty Library, which was used in Rodney's great action of April 12, 1782, and drawn up by an officer who was present, a similar article is referred to.

But there it appears as No.XVII.of the Additional Instructions, and its effect is given in a form which closely resembles the original article of Hawke:--'When in a line of battle ahead and to windward of the enemy, to alter the course to lead down to them; whereupon every ship is to steer for the ship of the enemy, which from the disposition of the two squadrons it may be her lot to engage, notwithstanding the signal for the line ahead will be kept flying.' It is clear, therefore, that between 1780 and 1782 Rodney or the admiralty had issued a new set of 'Additional Instructions.' The amended article was obviously designed to prevent a recurrence of the mistake that spoiled the action of 1780.

In the same volume is a signal which carries the idea further.
