The proximity of New York insured frequent visits of opera companies from that city, and it may be said without exaggeration that from this time forward New York was almost exclusively the source of supply for opera in Philadelphia. So much is this so that to follow the history of opera in the former city is practically to follow it in the latter, except that New York was a base and Philadelphia a visiting point. Opera in English by the Woods was a feature of the Philadelphia season in 1843 and, in the following year, the Rivafinoli Opera Troupe, which we have already met in New York, gave a season of ten nights. Cimarosa's _Matrimonio segreto_ was the most interesting of their offerings. More opera in English by the Woods, the Seguins, Caradori-Allan, Fanny Elssler, and others occupied musical Philadelphia until 1845, the only break being a short season in 1843 by an Italian company which presented _Norma_, _Lucia di Lammermoor_, _Belisario_, _I Puritani_, and _Gemma di Vergy_. The New Orleans company reappeared in 1845 with _La Favorite_, _La Fille du régiment_, _Robert le diable_, _Le Domino noir_, _La Muette de Portici_, _L'Ambassadrice_, _La Juive_, and _Les Huguenots_. The Havana troupe, which we met in New York, regaled Philadelphia in 1847 with Pacini's _Saffo_, Verdi's _Ernani_, _I Lombardi_ and _Due Foscari_, with Bettini's _Romeo e Giuletta_, with _La Sonnambula_, _Mosé in Egitto_, _Norma_, and _Linda di Chamouni_. The Seguins still continued to give opera in English. Sanquirico and Patti brought their company from New York in 1848, without setting the Delaware on fire, though they included _Don Giovanni_ in their extended répertoire. They remained in Philadelphia until 1851, when the Havana troupe appeared with a splendid company, including Bosio, Bertucca, Salvi, and Marini. The only novelty produced by the Havana company was _Don Pasquale_, but their performances were artistically the finest that had been heard in Philadelphia. In 1852 the Seguins produced Verdi's _Luisa Miller_ for the first time in America. Both Albani and Sontag appeared in Philadelphia in 1853 with the old Rossini-Bellini-Donizetti program, and a similar repertory secured the appearances of Grisi and Mario in 1855. _Il Trovatore_ was heard in 1856 with Brignoli and Anna La Grange. Opera in English still continued under various auspices.
