Boston Museum.

"One Hundred Years Old," a new drama in five acts, was presented at this theatre on Monday night. The play itself is very improbable in plot, and depends for its interest entirely upon good acting, which, it is needless to say, it receives from the Museum Company. Jacques Fauvel, "Le Centenaire," is the central figure of the piece, and the part was acted by Mr. Warren in a manner to put the impersonation on a par with his greatest achievements. Jacques Fauvel is not a senile dotard on the verge of the grave, but a hale and hearty old man, with every mental faculty intact and enlarged by years of experience, and with much bodily vigor still remaining. In every change of facial expression, in every motion of his body, Mr. Warren's acting was a thing for study and admiration. The clear insight of Jacques Fauvel into character and motives; his transcendent love for his great-grandchild, most effectively shown in the scene where he supposes her lost; his confidence in the poor girl when all but he forsake her, - all were wonderfully real in Mr. Warren's impersonation. His dressing was, as usual, most admirably suited to the part. The other important character in the play is that of the self-sacrificing Camille, a part well suited to Miss Clarke, who certainly acted never better or looked more beautiful. Mr. Hardenbergh and Mr. McClannin were both acceptable in their respective parts. If Mr. Conway would stop shaking his leg and running his hand through those flowing locks, he would greatly relieve the Museum audiences.
