Martinière says that she was burnt alive, together with all the papers respecting her trial. The latter is improbable, and the former certainly false, notwithstanding the account given in the Encyclopédie.

The following description of Brinvillier may perhaps be of use to our physiognomists: – “In order to satisfy the curiosity of those who may be desirous of knowing if such a celebrated criminal partook of the beauties of her sex, I shall observe that nature had not been sparing of them to the marchioness; her features were exceedingly regular, and the form of her face, which was round, was very graceful. This beautiful outside concealed a heart extremely black. Nothing proves more that metoposcopy , or the science of physiognomy, is false; for this lady had that serene and tranquil air which announces virtue.” – Pitaval, p. 269.

Some information respecting La Voisin may be found in Lettres Historiques et Galantes par Madame de C – . A Cologne, 1709–1711, 4 vols. 12mo, ii. p. 101, and iv. p. 376. The authoress of these letters was Mad. du Noyer.

This anecdote was told to me by the celebrated Linnæus. An account of what appeared on opening the body of this prince may be seen in Baldinger’s Neues Magazin für Aerzte, vol. i. p. 91.

“The lieutenant-civil continued still to grow worse. After having languished a long time, being seized with a loathing of every kind of food presented to him, his vomitings still continuing, and nature being at length exhausted, he expired without any fever. The three last days he had wasted very much; he was become extremely shrunk, and he felt a great heat in his stomach. When opened, that part and the duodenum were found to be black, and sloughing off in pieces; the liver was mortified, and as it were burnt. The counsellor was ill three months, had the like symptoms as the lieutenant-civil, and died in the same manner. When opened, his stomach and liver were found in a similar state.” – pp. 274, 275.

In one year a ton of sand, at least, which is baked with the flour, is rubbed off from a pair of mill-stones. If a mill grinds only 4385 bushels annually, and one allows no more than twelve bushels to one man, a person swallows in a year above six pounds, and in a month half a pound of pulverized sandstone, which, in the course of a long life, will amount to upwards of three hundred weight. Is not this sufficient to make governments more attentive to this circumstance?

[Although not very agreeable to the reader to learn that he swallows above six pounds of mill-stone powder in the course of the year, it may perhaps ease his mind to know that the learned author is entirely mistaken in regarding it as a poison. The inhabitants of the northern countries of Europe frequently mix quartz powder with their heavy food to assist in its digestion; and we are informed by Professor Ehrenberg, that in times of scarcity, the inhabitants of Lapland mix the siliceous shells of some species of fossil Infusoria with the ground bark of trees for food. It is probably from this circumstance that the infusorial deposit derives its name of Berg-mehl , or Mountain-meal .]

For the following important information I am indebted to Professor Baldinger: – “There is no doubt that the slow poison of the French and Italians, commonly called succession powder ( poudre de la succession ), owes its origin to sugar of lead. I know a chemist who superintends the laboratory of a certain prince on the confines of Bohemia, and who by the orders (perhaps not very laudable) of his patron, has spent much time and labour in strengthening and moderating poisons. He has often declared, that of sugar of lead, with the addition of some more volatile corrosive, a very slow poison could be prepared; which, if swallowed by a dog or other animal, would insensibly destroy it, without any violent symptoms, in the course of some weeks or months.”

Garelli, the emperor’s principal physician, lately wrote to me something remarkable in the following words: – “Your elegant dissertation on the errors respecting poisons brought to my recollection a certain slow poison, which that infamous poisoner, still alive in prison at Naples, employed to the destruction of upwards of six hundred persons. It was nothing else than crystallised arsenic, dissolved in a large quantity of water by decoction, with the addition, but for what purpose I know not, of the herb cymbalaria. This was communicated to me by his imperial majesty himself, to whom the judicial procedure, confirmed by the confession of the criminal, was transmitted. This water, in the Neapolitan dialect, is called aqua del Toffnina . It is certain death, and many have fallen a sacrifice to it.” – Hoffmanni Med. Rationalis System., p. ii. c. 2. § 19.

On the 20th of December, 1765, died the dauphin, father of Louis XVI., and in 1767 died the dauphiness. It was a public report that they were both despatched by secret poison: and the gradual decline of their health, the other circumstances which accompanied their illness, and the cabals which then existed at court, make this at least not improbable. Many private anecdotes respecting these events may be found in a book entitled L’Espion Dévalisé. Feliciter audax. London, 1782. In page 61 it is said, that on account of the suspicions then entertained, it was wished that information might be procured respecting secret poison, and the methods of preparing it; and that the abbé Gagliani, well known as a writer, has given the following: – “It is certain that in Europe the preparation of these drugs renders them pernicious and mortal. For example, at Naples the mixture of opium and cantharides, in known doses, is a slow poison; the surest of all, and the more infallible as one cannot mistrust it. At first it is given in small doses, that its effects may be insensible. In Italy we call it aqua di Tufania , Tufania water. No one can avoid its attacks, because the liquor obtained from that composition is as limpid as rock water, and without taste. Its effects are slow and almost imperceptible: a few drops of it only are poured into tea, chocolate, or soup, &c. There is not a lady at Naples who has not some of it lying carelessly on her toilette with her smelling-bottles. She alone knows the phial, and can distinguish it. Even the waiting-woman, who is her confidant, is not in the secret, and takes this phial for distilled water, or water obtained by precipitation, which is the purest, and which is used to moderate perfumes when they are too strong.

“The effects of this poison are very simple. A general indisposition is at first felt in the whole frame. The physician examines you, and perceiving no symptoms of disease, either external or internal, no obstructions, no collection of humours, no inflammations, orders detergents, regimen, and evacuation. The dose of poison is then doubled, and the same indisposition continues without being more characterized. The physician, who can see in this nothing extraordinary, ascribes the state of the patient to viscous and peccant humours, which have not been sufficiently carried off by the first evacuation. He orders a second – a third dose – a third evacuation – a fourth dose. The physician then sees that the disease has escaped him; that he has mistaken it, and that the cause of it cannot be discovered but by changing the regimen. He orders the waters, &c. In a word, the noble parts lose their tone, become relaxed and affected, and the lungs particularly, as the most delicate of all, and one of those most employed in the functions of the animal œconomy. The first illness then carries you off; because the critical accumulation settles always on the weak part, and consequently on the lobes of the lungs; the pus there fixes itself, and the disease becomes incurable. By this method they follow one as long as they choose for months, and for years. Robust constitutions resist a long time. In short, it is not the liquor alone that kills, it is rather the different remedies, which alter and then destroy the temperament, exhaust the strength, extenuate and render one incapable of supporting the first indisposition that comes.”
