[5] They returned to the United States in late 1847 when Biscaccianti was offered a contract at the Astor Opera House in New York City.

[6] Madame Biscaccianti received from a large and highly intelligent audience, on the occasion of her re-appearance, last evening, one of the most flattering welcomes that we have ever seen bestowed upon a public favorite.

It was her first concert in several weeks, and she had barely recovered from an illness which still left its enfeebling effects upon her frame; but her voice was strong, pure and exquisitely flexible, and her spirits buoyant and animated.

She sang with a degree of fervor and expression that called for the most enthusiastic testimonials, in the forms of plaudits, "bravos" and bouquets, from a delighted auditory.

In the ten months that she remained in California she sang at least seventy recitals, thirty-five in San Francisco, thirteen in Sacramento, seven in Stockton, and the balance in smaller towns.In 1853 Biscaccianti performed in operas in South America, including in Lima, Peru.
