In February, 1815, the university was remodelled by the Bourbon government, and Cuvier was appointed a member of the Royal Council of Public Instruction. Shortly afterwards came the events of the Hundred Days, and among them the restoration of the Imperial University. Cuvier was re-appointed to his seat in the Council, for they felt that they could not do there without him. In four months another revolution took place in the university, as in other public establishments; and as it was found that the system of the Royal University could not be resumed, a commission was appointed to execute the functions of the Grand Master, the Chancellor, and the Treasurer. In this commission the duties which had belonged to the Chancellor were assigned to Cuvier. In this station he was eminently useful in maintaining the rights of the university under circumstances of no ordinary difficulty. He was twice President of the Commission, and each time for a year; but on account of his being a Protestant he could not retain that place permanently. But the Bishop, who, as a member of the commission, had discharged the duties which belonged to the Grand Master of the University, was appointed minister for ecclesiastical affairs; and Cuvier was nominated as his successor, so far as concerned the Protestant faculty of theology, and continued to act in this capacity for the rest of his life. As a member of the Council of State, and attached to the department of the Minister of the Interior, he had the direction of all matters relating to Protestant, and other religious congregations, not Catholic. During his mission to Rome in 1813 he was appointed by Napoleon a member of the Council of State; and on the restoration of the Bourbons his political opinions formed no obstacle to his continuing in that place. Although he was left undisturbed in his situation at the university, he was removed from the Council of State during the Hundred Days; but resumed his seat when the fate of his former patron and master was sealed. It is to be regretted that a mind so powerful as that of Cuvier should not have felt the paramount importance of having settled opinions on the great principles of government; and the facility with which he made himself acceptable to the despotic Emperor, the weak and bigoted Bourbons, and the liberal government of Louis Philippe, showed a want of fixed public principle which casts a shade upon the memory of this great man.
