The girl bad spared no effort to ingratiate herself, not only with the empress, but with the grand-duke and the Russian people. She applied herself to learning the language with such zeal that she rose at night and walked about her bedroom barefoot repeating her lessons. The result was a severe attack of congestion of the lungs in March 1744. During the worst period of her illness she completed her conquest of the goodwill of the Russians by declining the religious services of a Protestant pastor, and sending for Simon Todorskiy, the orthodox priest who had been appointed to instruct her in the Greek form of Christianity. When she wrote her memoirs she represented herself as having made up her mind when she came to Russia to do whatever had to be done, and to profess to believe whatever she was required to believe, in order to be qualified to wear the crown.
