Having ordered three fagots of wood, which is the quantity generally used by bakers, to be thrown into the oven, and they being set on fire, twelve more fagots of the same size were subsequently added to them, which being all consumed by three o'clock, M.Chabert entered the oven with a dish of raw meat, and when it was sufficiently done he handed it out, took in another, and remained therein until the second quantity was also well cooked; he then came out of the oven, and sat down, continues the report, to partake, with a respectable assembly of friends, of those viands he had so closely attended during the culinary process.
Publicly, on a subsequent day, and in an oven 6 feet by 7, and at a heat of about 220, he remained till a steak was properly done, and again returned to his fiery den and continued for a period of thirty minutes, in complete triumph over the power of an element so much dreaded by humankind, and so destructive to animal nature.

It has been properly observed, that there are preparations which so indurate the cuticle, as to render it insensible to the heat of either boiling oil or melted lead; and the fatal qualities of certain poisons may be destroyed, if the medium through which they are imbibed, as we suppose to be the case here, is a strong alkali.

Many experiments, as to the extent to which the human frame could bear heat, without the destruction of the vital powers, have been tried from time to time; but so far as recollection serves, Monsieur Chabert's fire-resisting qualities are greater than those professed by individuals who, before him, have undergone this species of ordeal." It was announced some time ago, in one of the French journals, that experiments had been tried with a female, whose fire-standing qualities had excited great astonishment.

She, it appears, was placed in a heated oven, into which live dogs, cats, and rabbits were conveyed.
The poor animals died in a state of convulsion almost immediately, while the Fire-queen bore the heat without complaining.

In that instance, however, the heat of the oven was not so great as that which M.Chabert encountered.
Much of the power to resist greater degrees of heat than can other men may be a natural gift, much the result of chemical applications, and much from having the parts indurated by long practice; probably all three are combined in this phenomenon, with some portion of artifice.
