Dedicated to Nadezhda Petrovna Opochinina To the memory of Beltov and Liuba,41
1 October 1859
Neither Sofia Ivanovna nor you could have thought up anything better. We all await you with impatience. Maman asks me to tell you that "you are very nice and arrange everything beautifully." Yesterday we saw Alexander and Nikolai Stasov; they told us about the return [from abroad] of Dmitri, who has brought back a lot of interesting stuff.--If I am able to find out by tomorrow morning from Vladimir whether they will be home in the evening, that would be fine, and in any case we have promised to be at their place on Sunday. Bring Schumann, I am thirsty for work.
Till we meet, Mili, expecting you tomorrow.

In the autumn of 1859, I again encountered him at the house of S. A. Ivanovsky, an assistant professor at the Academy [of Medicine] and doctor at the Artillery School. Musorgsky had already left the service. He had grown much more manly and rather stouter in appearance; the flavor of a foppish army officer had disappeared. The elegance in dress, manner, etc., was the same as before but not the slightest trace of dandyism remained. We were introduced, but at once we recognized each other, and recalled our first meeting at Popov's. Musorgsky declared that he had left the service in order to "devote himself entirely to music, as it was impossible to combine____________________
This is the earliest of the very few documents in evidence of Musorgsky's intimacy with Nadezhda Petrovna Opochinina.
