Tlie ripuntsh Studeutn.The entertainment last night, in ad-diiton to considerable musical merit, was something of a novelty and an innovation. The Spanish Students are a pleasing group, arrayed in black velvet with shoulder knots of gay ribbons; four perform on the light guitar and five on the still lighter bandurria or mandolin, and a very handsome party with the dignity of a hidalgo gracefully wields a leader’s baton.There were none of the so-calledweird and peculiar Spanish music, buta pleasing selection of very familiarairs, marches, waltzes and songs without words, flowed smoothly as from a piano from the instruments, in beautiful time, and with delicately shaded expression. The favorite overture from Martha was given with almost orchestral effect and the spirited performance of the national airs aroused the audience to enthusiastic applause. One multiplex player added occasionally the effect of a triangle, tamborine and castonets. The programme was varied by the recitation of J. J. Hays and the performance by D. W. Robertson on the tamborine. Mr. Hays read agreeably some very well known pieces and is very good in Irish dialect. Robertson plays quite remarkably upon a lot of glass goblets producing tunes similar to a flageolet. His selections were from II Travatore, negro melodies and that “Sweet Bye and Bye,” for which Lotta was kissed in London the other day. The discriminating audience gave this musical trick the most emphatic applause. The performance of the Spanish Students was evidently appreciated and the audience was gratified by an addition of extra numbers to the programme.
