In accordance with the first principle of historical criticism, it is important at the outset to determine exactly the value of the sources whence we may derive particulars serviceable to our investigation. The sources are divided into three well-marked categories-(1) The reports of the physicians and surgeons; (2) the accounts of the persons who were able to approach Madame in her last moments, or were in a position to hear authoritative descriptions; (3) the official correspondence of the courts of London and Paris.
The first category presents to us five reports of the post-mortem examination:-
(a) The official report signed by the fifteen physicians and surgeons, French and English, who were present at the autopsy.
(b) The Account of the Illness, Death, and Autopsy of Madame, by the Abbé Bourdelot, physician. Bourdelot was one of the French physicians present at the post-mortem.
(c) The report of Vallot, physician to the late queen-mother. Vallot was regarded as one of the most eminent physicians of his time. He was present among the French doctors at the autopsy. His report was officially carried to London by the Marshal de Bellefonds.
(d) The Memoir of a Surgeon of the King of England who was present at the Opening of the Body. This surgeon's name was Alexander Boscher.
(e) The account of Hugh Chamberlain, physician-in-ordinary to the King of England, also present at the operation. This document, like the preceding, is exceedingly useful for checking the official report and the report of the French physicians. Some writers have believed that Louis XIV, fearing a rupture with England, dictated the opinion the French physicians were to give. Boscher and Chamberlain were absolutely independent representatives of the English Government.
To these five documents, of unquestionable authenticity, may be added the notice inserted in the Gazette of July 5, 1670, which was officially inspired by the Court physicians, and the opinion of the famous Guy Patin, Dean of the Medical School of Paris, though he was not actually present at the autopsy.
In our second category, the narratives of persons who approached Madame in her last moments, or heard authoritative accounts, we must mention prominently the account written by the charming Countess de la Fayette, The History of Madame Henrietta of England, first wife of Philip of France, Duke of Orleans. The Countess de la Fayette was attached to the suite of Madame; she never left her during the day on which she died. She has left a simple, precise, and sober account of the short illness, in which every line bears the stamp of truth.
Next to this valuable document must be cited the letter of Bossuet, who was present at the final scene, and the story of Feuillet, canon of St. Cloud, who was with Madame before Bossuet arrived.
The third category comprises the correspondence exchanged between the courts of England and France and their representatives: these would be documents of the greatest value, if their official and diplomatic character had not imposed the greatest reserve on the writers, and even dictated their sentiments. There are first of all the letters of Louis XIV and Hugues de Lionne to Charles II and to Colbert de Croissy, ambassador at London; then, the despatches of Louis and of Hugues de Lionne to Monsieur de Pomponne, ambassador at the Hague; on the English side, five letters addressed by Lord Montagu, ambassador at the French Court, to Lord Arlington, secretary of state to Charles II, and the letters of Lord Arlington to Sir William Temple.
Such are the only documents worthy of credence we have at our disposal for studying the circumstances of the death of Madame, for it is necessary to reject in the most absolute manner the accounts of Saint-Simon and of Monsieur's second wife, Madame Palatine. Chéruel, and more especially Monsieur de Boislisle, have shown the improbabilities and absurdities of these, and we shall not refer to them again. The work of Monsieur de Boislisle is particularly interesting in showing that these two famous narratives had a common source. As to the testimony of d'Argenson, Voltaire, and others, destitute, in the nature of the case, of any authority comparable to that of the authors we have mentioned above-it is unnecessary in the points where it confirms the others; on the points where it contradicts them, it cannot prevail; and on the points where it contains new information, it is dangerous to follow, for we lack any evidence by which to check it. Littré acted judiciously in neglecting these writers when compiling his study on the death of Madame, and the reproach levelled against him by Loiseleur is without justification. On the contrary, it is perhaps to this happy stroke of criticism that Littré owed the success of his argument.
