States was the Magdalen Society of Philadelphia, founded in 1800. Other North American cities, including New York, Boston, Chicago, and Toronto, quickly followed suit. Asylum records show that in the early history of the Magdalene movement, many women entered and left the institutions of their own accord, sometimes repeatedly. Lu Ann De Cunzo wrote in her book, Reform, Respite, Ritual: An Archaeology of Institutions; The Magdalene Society of Philadelphia, 1800–1850, that the women in Philadelphia's asylum "sought a refuge and a respite from disease, the prison or almshouse, unhappy family situations, abusive men, and dire economic circumstances." In its early years, the Magdalen Society Asylum functioned as a refuge for prostitutes. Most of these stayed a few days or a few weeks, just long enough to get reclothed and recuperated. Attempts at rehabilitation met with little success. In 1877, the asylum was changed into a home for "wayward girls", with a rule requiring a stay for twelve months. As the Magdalen Society Asylum became more selective, relaxed its emphasis on personal guilt and salvation, and standardized the treatment of inmates, its rate of failure diminished. The Penitent Females' Refuge Society of Boston was incorporated in 1823. New York's Magdalen Society was established in 1830 with the purpose of rescuing women from lives of prostitution and vice. Advocates of women sometimes kidnapped them from brothels. In 1907 a new home was established in the Inwood section of upper Manhattan. The Society had twice moved to a larger facility. Many of the young women who were temporary residents at the Inwood institution had worked in the taverns, brothels, and alleyways of lower Manhattan before being "rescued" by the Society. Girls were generally committed for a period of three years. Through the years, several girls died or were injured climbing out of windows in failed escape attempts. In 1917, the Magdalen Benevolent Society changed its name to Inwood House. In the early 1920s, bichloride of mercury was commonly used to treat new arrivals for venereal disease, as penicillin was not yet available. Some women suffered mercury poisoning, as happened with patients on the outside. The property was later sold and the agency relocated. Inwood House continues to operate, with its main focus on teen pregnancy. Canada (1848) The Congregation of the Sisters of Misericorde was founded in Montreal in 1848 by Marie-Rosalie Cadron-Jetté, a widow skilled as a midwife. Their network of asylums
