Violently attacked by the Boulangist organs, L'Intransigeant and La France, he won a suit against them for libel, and in 1889 he contested the 18th arrondissement of Paris with General Boulanger, who obtained a majority of over 2000 votes, but was declared ineligible.
A Boulangist "movement" was now in full swing.
Was the end of the political danger, though Boulangist echoes continued for a little while to reverberate at the polls during 1889 and 1890.
He energetically defended the republic against the Boulangist agitation, and took an equally courageous part in the Dreyfus affair.
He was elected Boulangist deputy for the 18th Parisian arrondissement in 1889.
Although he finally intervened on the side of Flourens, and peace was preserved, his weakness in face of the Boulangist propaganda became a national danger.
He was defeated at the polls by a Boulangist candidate in 1889, and sat in the senate from 1891 to 1893, when he returned to the popular chamber.
Two years later he re-entered the Senate, where he did good service to the cause of "Republican Defence" during the Boulangist agitation.
