He was a pupil of the Ecole des Beaux-Arts at Toulouse, and then in Paris of Cogniet and Bida. His compositions, depicting for the most part tragic and often gruesome epi- sodes, are intensely dramatic in style and spirited in execution, and never fail to produce a deep impression, although their effect is frequently marred by an exaggerated realism and lack of harmonious coloring. Out of their considerable number mav be mentioned : '"Death of Tiberius" (1864) ; "A Voice in the Desert" (1808. Orleans Museum) ; "Execution of the Due d'Enghien" (1872.

Havre Museum) ; "Excommunication of King Robert the Pious, 1004" (1875, Luxembourg) : "The Austrian Gen- eral Staff Around the Deathbed of General Mar- ceau" (1877. Ghent Museum), one of his finest works, which received the medal of honor in the Salon; "Release of the Immured at Car- cassonne. 1303" (1870, Luxembourg): "Ven- geance of Pope Urban VI." (1886); "Entrv of Louis XVI. into the Hotel de Ville, Paris'" (isni) ; and "X'apoleon and Pius VII. at Fon- taineblean" (1894).

He as born in South Carolina ; was educated in England, and in 1777 entered the Continental .rmy as one of Washington's aides. In this position he discharged many of the duties of a private secretary, and his familiarity with for- LAURENTIAN SYSTEM. eign languages enabled him to be of great ser- vice in conducting the necessary correspondence with European officers in the .service. He is said to have participated in all of Washington's bat- tles, in several of which, while fighting with the utmost bravery, he was severely wounded. Early in 17S1 he was sent on a special mission to France, and by appealing directly to the King, in spite of diplomatic precedents, succeeded in negotiating a loan. At Vorktown lie served with reckless daring, and in the following year, while on the staff of General Greene, was killed (Au- gust 27th) in an insignificant skirmish on the Conibahee River. His unusual abilities, coupled with his gallantry, his courtesy, and his chival- rous devotion to his country, made him a uni- versal favorite, and won for him the title of the 'Bayard of the Revolution.' The array cor- respondence of Laurens, together with a brief memoir, by W. G. Simms, was privately printed in 18C7 by the Bradford Club (New York). LAURENS, .Joseph Augu.stin Jl-les (1825- — ).
