"Written with the greatest possible conciseness, this work could not be comprised in less than eight volumes in 8vo, namely: One volume for the quadrupeds and birds; one volume for the reptiles and fishes; two volumes for the insects; one volume for the worms (the molluscs, madrepores, lithophytes, and naked worms); two volumes for the plants; one volume for the minerals: eight volumes in all. "It is impossible to prepare in France a work of this nature without having special aid from the nation, because the expense of printing (on account of the enormous quantity of citations and figures which it would contain) would be such that any arrangement with the printer or the manager of the edition could not remunerate the author for writing such an immense work. "If the nation should wish to print the work at its own expense, and then give to the author the profits of the sale of this edition, the author would be very much pleased, and would doubtless not expect any further aid. But it would cost the nation a great deal, and I believe that this useful project could be carried through with greater economy. "Indeed, if the nation will give me twenty thousand francs, in a single payment, I will take the whole responsibility, and I agree, if I live, that before the expiration of seven years the _Système de la Nature_ in French, with the complemental addition, the corrections, and the convenient explanations, shall be at the disposition of all those who love or study natural history." FOOTNOTES: [32] Most men of science of the Revolution, like Monge and others, were advanced republicans, and the Chevalier Lamarck, though of noble birth, was perhaps not without sympathy with the ideas which led to the establishment of the republic. It is possible that in his walks and intercourse with Rousseau he may have been inspired with the new notions of liberty and equality first promulgated by that philosopher. His studies and meditations were probably not interrupted by the events of the Terror. Stevens, in his history of the French Revolution, tells us that Paris was never gayer than in the summer of 1793, and that during the Reign of Terror the restaurants, _cafés_, and theatres were always full. There were never more theatres open at the same period than then, though no single great play or opera was produced. Meanwhile the great painter David at this time built up a school of art and made that city a centre for art students. Indeed the Revolution was "a grand time for enthusiastic young men," while people in general lived their ordinary lives. There is little doubt, then, that the savants, except the few who were occupied by their duties as members of the _Convention Nationale_, worked away quietly at their specialties, each in his own study or laboratory or lecture-room.
