It is dedicated to the first lord of the admiralty, and entitled _A Narrative of the Proceedings of his majesty's fleet in the Mediterranean_, 1741-4, including, amongst other matter relating to Mathews's action, 'some signals greatly wanted on the late occasion.' At p.

108 are some 'Additional signals made use of by our fleet in the West Indies,' meaning that of Admiral Vernon, which Lestock had recently left.

These signals relate to sailing directions by day and by night, to 'seeing ships in the night' and to 'engaging an enemy in the night,' and immediately following them are two 'Additional Instructions to be added to the Fighting Instructions.' The inference is that these two 'Additional Instructions' were something quite new and local, since they were used by Vernon and not by Mathews.

They are given below, and will be found to correspond closely to Articles I.and III.

of the set used by Boscawen in the next war.
