 We stated that the ability of the human of heat as had been exempli6ed in the case of Mons. Chaubert, and J. H. Patten, Esq. was capable of explanation on scientific principles. The theories to which we al- luded were those of Dr.. Black of Edin- burg, and especially the one relative to lat ent heat. The explanation of the matter given by MT. P. is founded upon that theo- ry, and appears to us to be both rational and ingenious. It is this Ut is impossi- bIe for any fluid besides mercury, to trans init heat through itself except by an inter- charge of particles; and in all such cases the heated particles rise, according to the principles of gravitation. If you apply a may evaporate, it very fast, but you can~~. heat it. Fluids are perfect non-conductors of heat. A living human beMg may be considered. as vessel filled with fluid which is constantly exuding through eve- ry part of the surface, which surface is re- plenished from the interior reservoir as fas, as it is evaporated. Take first the exPcri- ment of the boiling oil. The oil is heated to or 500 degrees of Fahrenheit. The finger is then dipped into the vessel, and the heat is employed in converting the per- spiration upon it into vapor :the evapora- ton is constantly supplied from the vessels within, and the finger cannot burn until one or two things take place; either the oil must be soshot as to evaporate the per- spiration faster than it can be supplied, oI the finger must remain in the oil long en. ough to exhaust its precipitation. This ii the reason why it is necessary to perform the experiment SO quickly. It is the same with melted lead. The putting it on thu tongue is nero parade; for the smal quantity taken up between the finger i cooled before it gets to the tongue.

 Entering the oven is dependant on th' same principle. The moment you ente 1 the oven, the heat is employed in convert
