Miss Sieveking published several works. These were for the most part merely transcripts of the religious instruction given to her pupils. They were read in many circles, and met with very different receptions; but they certainly contain a vast amount of practical wisdom and judicious suggestions on the whole subject of charitable work, and organizations of women for that purpose. Amid these varied labours and experiences, one thought was ripening in her soul. She had read a little French book in which there was much said of the sisters of charity among the Roman Catholics, and it awakened in her a strong desire to found such a sisterhood in the Protestant Church. She had been led to this by the fact, that in hundreds of instances unmarried women are not permitted to do the good to which their hearts impel them, because they have not the settled position which would be given by a definite calling, recognised as such by the world without. With a longing after this work which had only increased in intensity from being so long pent up within, we cannot but admire the Christian wisdom and moderation with which she viewed the matter, even when encouraged by the approval of friends. In the autumn of 1824, Miss Sieveking became acquainted with Pastor Gossner, a Bavarian by birth, who had been a priest in the Roman Catholic Church, but by deep study of the holy Scriptures had been converted to the evangelical doctrines. This good and great man gave a new and powerful impulse to her aspirations after what now floated before her as the future vocation of her life. Charitable work now engaged so much of her thought and sympathy that her health, usually so strong, began to give way; but the water of Ems proved beneficial, and old strength and fresher looks returned. In 1826, Professor Tscharner of Berne, who had been imprisoned in his own country, was giving lectures in Hamburg, and Miss Sieveking spent many happy hours with himself, his wife, and his son. Here also, in 1828, she became intimately acquainted with the celebrated Neander, of Berlin. Nursed amid the sultry climes of India, where it periodically slays its thousands and tens of thousands, the cholera seems occasionally to take migratory and comet-like excursions to Europe, spreading on every hand sickness, death, lamentation, and dismay. In 1831, it suddenly appeared in Hamburg; and Miss Sieveking felt constrained to take a step which, in the eyes of the world, had something _unusual_ in it, and was judged by that world accordingly. With the full consent of her adopted mother, she offered her gratuitous services as nurse in the French wards of the town hospital. She also inserted in a journal an appeal to other females to offer themselves for the same work, but her letter found no response. Our own Florence Nightingale had not yet set the example of a lady voluntarily consecrating herself to such an office.
