The summons she awaited was not long in reaching her, and so we find her on the 11th January, 1832, starting for London, which she reached safely, and lost no time in getting into active service. She called on Carlile in the Giltspur Street prison, and after a lengthy consultation with him, set about opening up the Rotunda again. It is needless to say that Carlile was more than pleased with the beauty and intelligence as well as the courage displayed by the young lady, and he accepted her as a veritable Joan of Arc for the cause to which he was devoted. Almost her first act was to go to Lord Melbourne and procure his permission to reopen the Rotunda on her promise that while she was in charge of it, there should be nothing but philosophic lecturers and discussions take place there. To Lord Melbourne she made known her name and family connections, as also her object, viz., to assist as much as possible to support both Carlile and Taylor while they were in prison. It is fair to say that the gentleman treated her kindly and granted her request. Isis delivered her first lecture at the Rotunda on the 29th of January, a little over two weeks after her arrival from Lancashire. From consideration for the feelings of her family, her mother most particularly, her name and connections were carefully concealed from the public, and she became known as the "Lady of the Rotunda". Isis, the name Carlile had given her in his letters, was adopted as the name of a weekly publication which was started in February and kept up for about two years. Naturally, the novelty of the proceeding, combined with the beauty and talent of the lady, and the mystery surrounding her, drew many hearers. She was the first woman to take the platform as an independent thinker and public speaker in England. Almost, as a matter of course, she was inundated by letters of adoration, curiosity, approbation and so on, and proposals of all kinds. Any of these that seemed to carry a double purpose in it were answered publicly in the columns of the _Isis_. She preserved her _incognita_ completely so far as the public was concerned, and also kept herself free from all private calumny. On Sunday and two or three times a week she lectured at the Rotunda and various other places by invitation. The study necessarily incident to these frequent lectures occupied the whole of her time, and except for her visits to Carlile in prison in Giltspur Street, and the Rev. Robt. Taylor in Horsemonger Lane Gaol, she had no diversion of any kind. There is no doubt at all but that Carlile outlined all her lectures for her, for it would have been impossible for an inexperienced country girl with the ordinarily narrow education of her time and class to have been able to have pleased a metropolitan audience of reading and thinking men and women. As it was, she delivered the lectures in a very quiet and dignified manner, and at their close quietly left the platform, leaving to others the task of discussing or defending the arguments used or the merit or demerit of the discourse itself. Frequently her exit had to be made through a long double-lined passage of admirers. Flowers were offered in profusion. She would sometimes accept a few simple ones with an inclination of the head or a "Thank you", but never stayed her steps for an instant. She busied herself in procuring for Mr. Taylor a modification of his sentence, or at least some mitigation of the severities practiced upon him. Writing to Carlile from Horsemonger Lane Gaol, January 12, 1832, the Rev. Robt. Taylor says:--
