‎---- EDITION ORIGINALE ---- EXEMPLAIRE BIEN COMPLET DU SUPPLEMENT PARU EN 1837 qui a été relié, dans cet exemplaire, en tête du volume ---- "AN IMPORTANT WORK IN WHICH POISSON FORMULATES EQUATIONS FOR THE DISTRIBUTIONS OF HEAT IN BODIES. As opposed to Fourier, who maintained in his mémoire analytique de la chaleur that the conductibility of heat was contained in the motion of flux, POISSON showed that it must be derived form an absorptive coefficient restoring the neglected functionall dimension. Following his preliminary notes, POISSON devotes chapters to the laws of radiating heat, laws of cooling for bodies which have the same temperatue at all points, the movement of heat in the interior of solid bodies or liquids, movement of heat to the surface of a body of any form, digression on the integrales of equations with partial differences and a digression on the manner of expressing arbitrary functions by series of periodic quantities followed by a continuation of he same digression. Additional chapters are devoted to the distribution of heat in a bar whose transversal dimensions are very small, distribution of heat in spherical bodies and distributio of heat in various bodies, especially in a homogenous sphere originally warned in any manner, and the movement of heat in the interior and at the surface of the earth. He concludes with a series of three notes, the first relative to the equation of movement for heat at the interior of bodies, the second on molecular radiation, and the third relating to section 152 of the texte.... The supplement consists of a memoir read to the Academy of Science, to which have been joined some notes developing certain points in the memoir, principally relating to the temperatures of the globe and of space at different epoch".
