One of the presses of this cabinet was full of cardboard boxes, containing papers relative to the House of Austria, inscribed in the King's own hand: "Secret papers of my family respecting the House of Austria; papers of my family respecting the Houses of Stuart and Hanover." In an adjoining press were kept papers relative to Russia.

Satirical works against Catherine II.

and against Paul I.

were sold in France under the name of histories; Louis XVIII.
collected and sealed up with his small seal the scandalous anecdotes against Catherine II., as well as the works of Rhulieres, of which he had a copy, to be certain that the secret life of that Princess, which attracted the curiosity of her contemporaries, should not be made public by his means.
Above the King's private library were a forge, two anvils, and a vast number of iron tools; various common locks, well made and perfect; some secret locks, and locks ornamented with gilt copper.

It was there that the infamous Gamin, who afterwards accused the King of having tried to poison him, and was rewarded for his calumny with a pension of twelve thousand livres, taught him the art of lock-making.
