In the same collection, also, is a ring made to serve as a whistle. It is of lead, with circular bezel finely chased in relief, with profile heads of Charles the Fifth and his empress. Flemish, sixteenth century. Diameter one and one-eighth inch.

In the ‘Annual Register’ for 1764 we read that Mr. Arnold, of Devereux Court, in the Strand, watchmaker, had the honour to present His Majesty George the Third with a most curious repeating watch of his own making, set in a ring. The size of the watch was something less than a silver twopence; it contained 120 different parts and weighed altogether five dwts. seven grains and three-fourths.

Among curious ring relics may be mentioned one in which a tooth of Sir Isaac Newton was set. The tooth was sold to a nobleman in 1816 for 730l., who had it placed in the ring, and wore it constantly on his finger. Denon, the French savant, wore a ring set with a tooth of Voltaire.

At Norwich in 1847 a silver ring was exhibited, set with a dark-coloured substance, supposed to be the palatal tooth of a fish, like those of the Sphœrodus Gigas. This closely resembles the precious ring given (according to tradition) by Richard Cœur-de-Lion, to one of the Dawnay family in the Holy Wars, and adopted as their crest. It is preserved in the collection of Viscount Downe, and was shown by him at a meeting of the Institute at York. Another ring, with the same kind of setting, belonged to the late Mr. Albert Way. Date, the thirteenth century.

In the collection of Mr. A. J. B. Beresford Hope is a gold ring set with a sapphire of extraordinary brilliancy, known as the ‘saphir merveilleux,’ which formerly belonged to Philippe d’Orléans (Égalité), and is mentioned by Madame de Genlis.

In 1765, a very beautiful and perfect gold ring was found by a workman among the ruins of the North Gate House, on Bedford Bridge, when that building was pulled down. It bears the initials ‘J.B.,’ and is engraved with a death’s-head and the words ‘Memento mori.’ There seems to be every probability that this ring once belonged to John Bunyan, who was imprisoned there. This precious relic was sold to Dr. Abbot, chaplain to the Duke of Bedford, and presented by him in his last illness to the Rev. G. H. Bower, perpetual curate of Elstow, the birthplace of Bunyan.

The London press has lately announced that Dean Bower bequeathed to his nephew, Mr. Henry Addington, this ring.

In the preceding chapter I have mentioned several portrait-rings of remarkable interest; I may add that at the Loan Exhibition of Ancient and Modern Jewellery at the South Kensington Museum in 1872, some fine and highly curious specimens of this character were shown, and amongst them the following:—

Colonel Dawson Damer is the possessor of a gold ring with a miniature by Cosway of the eye of George, Prince of Wales.

Professor Maskelyne has an intaglio portrait of Sir Isaac Newton, set in a ring, which was presented to the late Dr. Maskelyne, Astronomer Royal, by Dr. Shepherd, of Cambridge, contemporary of Newton.
