[Illustration: STATUE OF THE ABBÉ DE L’EPÉE AT THE DEAF AND DUMB INSTITUTION.] The heart of Buffon may probably, like many others, have been stolen for the sake of its casket. Hearts intended to be preserved were usually enclosed in cases not of lead--as by exception the heart of St. Louis seems to have been--but of silver, and even gold. The precious metal was often, moreover, adorned with jewels of great value. Every precaution, in fact, was taken to render as difficult as possible the permanent preservation of the object which it was desired to keep for ever; and, as a natural result, the number of hearts which have come down to the present day is exceedingly small. Nearly all the hearts in cases now to be met with are those of modern celebrities. That of Voltaire--which after being reverently kept until his death by his friend and admirer, the Marquis de Villette, was at the Marquis’s death given by his heirs to the state--can be seen at the National Library of Paris. But the Hôtel des Invalides is, more than any other French establishment, rich in hearts of the great. There the hearts are religiously preserved of Turenne, of La Tour d’Auvergne, of Kléber, and of Napoleon. In England the encased heart best known to us is probably that “Heart of Bruce” celebrated in Aytoun’s “Lay” on the subject. Boece, in the story on which Aytoun’s poem is partly founded, relates that when Sir James Douglas was chosen as most worthy of all Scotland to pass with King Robert’s heart to the Holy Land, he put it in a case of gold, with aromatic and precious ointments, and took with him Sir William Sinclair and Sir Robert Logan, with many other noblemen, to the holy grave, “where he buried the said heart with the most reverence and solemnity that could be devised.” According to Froissart, however, and other authorities, Bruce’s heart was brought back to Scotland. Douglas, the keeper of the heart, encountering the infidels, endeavoured to cut his way through, and might have done so had he not turned to rescue a companion whom he saw in jeopardy. In attempting this he became inextricably mixed up with the enemy. Then taking from his neck the casket which contained the heart of Bruce, he cast it before him, and exclaimed with a loud voice, “Now pass onward as thou wert wont, and I will follow thee.” These were the last words and deeds of an heroic life. Douglas, quite overpowered, was slain; and it was not until the following day that the heart of Bruce and the body of Douglas were both recovered. Brought back to Scotland, the heart was deposited at Melrose, and the Douglas family have ever since carried on their armorial bearings a bloody heart. This is one of the few hearts which have been preserved to a good purpose, and its preservation in the present day is largely due to its having been embalmed in verse.
