Member of the American Academy of Arts and Sciences in 1832. In 1834, Arago again visited Scotland, to attend the meeting of the British Association at Edinburgh. From this time till 1848 he led a life of comparative quiet – although he continued to work within the Academy and the Observatory to produce a multitude of contributions to all departments of physical science – but on the fall of Louis-Philippe he left his laboratory to join the Provisional Government (24 February 1848). He was entrusted with two important functions, that had never before been given to one person, viz. the ministry of marine and colonies (24 February 184811 May 1848) and ministry of war (5 April 184811 May 1848); in the former capacity he improved rations in the navy and abolished flogging.

Cape Gregory in Oregon was named by Captain Cook on 12 March 1778 after Saint Gregory, the saint of that day; it was renamed Cape Arago after François Arago. Last years Arago remained a consistent republican to the end, and after the coup d'état of 1852, though suffering first from diabetes, then from Bright's disease, complicated by dropsy, he resigned his post as astronomer rather than take the oath of allegiance. Napoleon III gave directions that the old man should be in no way disturbed, and should be left free to say and do what he liked. In the summer of 1853 Arago was advised by his physicians to try
