The immensity of the mass, however, did not discourage the old Commissioners of the Academy. Let this conduct serve as an example to learned men, to administrators, who might be called upon to cast an investigating eye on the whole of our beneficent and humane establishments. Undoubtedly, the abuses, if any yet exist, have not individually any thing to be compared to those to which Bailly's report did justice; but would it be impossible for them to have sprung up afresh in the course of half a century, and that in proportion to their multiplicity, they should still make enormous and deplorable breaches in the patrimony of the poor? I shall modify very slightly, Gentlemen, the concluding words of our illustrious colleague's report, and I shall not in the least alter their innate meaning, if I say, in finishing this long analysis: "Each poor man is now laid alone in a bed, and he owes it principally to the gifted, persevering, and courageous efforts of the Academy of Sciences. The poor man ought to know it, and the poor man will not forget it." Happy, Gentlemen, happy the academy that can adorn itself with such reminiscences! REPORT ON THE SLAUGHTER-HOUSES. An attentive glance at the past has been, in all ages and in all countries, the infallible means of rightly appreciating the present. When we direct this glance to the sanitary state of Paris, the name of Bailly will again present itself in the first line amongst the promoters of a capital amelioration, which I shall point out in a few words. Notwithstanding the numerous acts of parliament,--notwithstanding the positive police regulations, which dated back to Charles IX., to Henry III., to Henry IV., slaughter-houses still existed in the interior of the capital in 1788; for instance, at l'Apport-Paris, La Croix-Rouge, in the streets of the Butcheries, Mont-Martre, Saint-Martin, Traversine, &c. &c. The oxen were, consequently, driven in droves through frequented parts of the town; enraged by the noise of the carriages, by the excitements of the children, by the attacks or barking of the wandering dogs, they often sought to escape,--entered houses or alleys, spread alarm everywhere, gored people, and committed great damage. Fetid gases exhaled from buildings too small and badly ventilated; the offal that had to be carried away gave out an insupportable smell; the blood flowed through the gutters of the neighbourhood, with other remains of the animals, and putrefied there. The melting of tallow, an inevitable annexation of all slaughter-houses, spread around disgusting emanations, and occasioned a constant danger of fire. So inconvenient, so repulsive a state of things, awakened the solicitude of individuals and of the public administration; the problem was submitted to our predecessors, and Bailly, as usual, became the reporter of the Academical Committee. The other members were Messrs. Tillet, Darcet, Daubenton, Coulomb, Lavoisier, and Laplace.
