O'Connor, it is said, published his father-in-law Condorcet's _collective_ works; but whether the edition of 1804 in 21 volumes is meant, I cannot determine, though I know no other; nor does this contain his mathematical writings. While outlawed in 1793 with the Girondist faction, he evaded, from October to March, 1794, the revolutionary search, when he poisoned himself, unwilling, he said, in some verses addressed to his wife, the sister of Marshal Grouchy, further to participate in the horrors of the period, though he had been most instrumental in preparing the way for them. He chose, however, the better side, in his conception, of the proposed alternative or dilemma: "Ils m'ont dit: Choisis d'être oppresseur ou victime; J'embrassai le malheur, et leur laissai le crime." Madame O'Connor, a child of five years old at her father's death, had a very faint recollection of him; but I perfectly remember him, with his ardent look, and, while still young, a grey head,--"a volcano covered with snow," as was observed of him. O'Connor's only child, a mild gentlemanly young man, but certainly not the inheritor of his parent's talents, predeceased him, so that no descendant, either of Condorcet or O'Connor, now survives. J.
