We visited Madame S—— and had some conversation with her which would have been agreeable but for the constant interruption of a parrot which screeched as if it had been hired for the occasion. She had accompanied Mr. Wells of Philadelphia last year to the monastery of the Trinity. Her son is to go with us to the Kremlin to-morrow. The appearance of Moscow must have greatly improved since its conflagration in 1812. It has lost, however, in a great degree, that romantic and Asiatic appearance which it formerly presented. The cumbrous and rude magnificence of palaces irregularly scattered among Tartar huts, has given place to airy and regular streets in all directions. It appears to be in a prosperous condition. That which chiefly distinguishes it from other cities is the immense number of churches. Their cupolas, of all colors and of all forms, rising above the summits of the houses and glittering in the sun, are very striking and imposing objects. In this respect no city in the world, except Constantinople, can be compared with it. In the evening we visited the Russian Theatre. Both the infernal regions and the Elysian fields were well represented on the stage. _Tuesday._ It rained all day. Dined with Madame Novaselsoff. She is one of the three daughters of —— Orloff, the youngest brother of the three who left no son—immensely rich—had one son, an only child, who was killed in a duel some nine years ago. Aide-de-camp of Emperor—Ischermoff was his antagonist. Both fell. His mother lives upon his memory. She says she is now building two churches, one on the spot where he expired and the other on her estate—-a monument. She has established schools, one on the Lancasterian plan, among her peasants. I told her she ought to live for her peasants and consider them her children. Her example also might produce great effect. She said she had no object to live for, and when it was the will of God, she would go cheerfully; that her affections were fixed on another world. She had a full length likeness of her son in her parlor, and different other portraits of him scattered about; his drawings, etc., etc. _Wednesday morning._ We visited the Foundling Hospital, or the Imperial House of Education, as it is called. We had a letter for Dr. Alfonskoi, the chief medical officer attached to the institution, and he, together with Baron Stackelberg, the superintendent, conducted us through the apartments. This hospital is the glory of Moscow and is the most extensive establishment of the kind in the world. It is perfectly well conducted in all its departments.
