The codes used by Howe himself in 1794, and by Duncan at Camperdown in 1797, follow it exactly.

A slightly modified form was issued by Jervis to the Mediterranean fleet, and was used by him at St.Vincent in 1797.

No copy of this is known to exist, but from the logs of the ships there engaged it would appear that, though the numbering of the code had been changed, the principal battle signals remained the same.

In 1799 a new edition was printed in the small quarto form.

In this the Signal Book and the Instructions were bound together, and were issued to the whole navy, but here again, though the numbers were changed, the alterations were of no great importance.[2] Reprints appeared in 1806 and 1808, but the code itself continued in use till 1816.
