Warsaw, Saturday Evening, May 23rd.—Divine service was held in our apartments in the morning, afternoon, and evening. We had intended going to the New Synagogue, but were deterred from doing so by the great difficulties which we had encountered last evening in going to and returning from the Great Synagogue. Thousands of persons had followed us nearly the whole way, and the gallery of the Synagogue was so dreadfully crowded with ladies, that serious apprehensions were entertained lest it might fall, when hundreds must have been killed. A strong body of police had secured our retreat.

At least five hundred ladies, the wives and daughters of our co-religionists, called on Lady Montefiore.

A girl twelve years old sang several Hebrew melodies; she had a fine voice. In the evening we had with us, for the second time, a little boy, eight years old, who played exquisitely on the violin. He also recited the portion of the Pentateuch selected for the Sabbath reading in the Synagogue, with several of the commentaries on the same, by heart; a very handsome child. By his extraordinary talent he supports his parents and family—in all ten persons. Sir Moses made him a present of a sum of money to enable him to pay for a master.

We again noticed that the walls of our room were admirably arranged, so that every word we speak could be distinctly overheard outside in a dark passage.

Warsaw, Sunday, May 24th.—Colonel du Plat called, having been requested by Sir Moses to accompany him to the Palace. Going there, we met the Prince as he was descending from his carriage; he was most polite, and begged us to come into the Palace. He was very sorry he could not see Sir Moses on Friday. Sir Moses told His Highness that he had come to take leave of him, and to inquire if he had any commands for him. The Prince said he was very sorry that he had been prevented from showing him more attention, but since the arrival of the Emperor his presence was required every quarter of an hour. Sir Moses spoke of the great desire of the Jews to be allowed to purchase land, and to cultivate it themselves; he also told the Prince that Mr Posener had promised to change his dress, which pleased him greatly, and his example would, he said, have great effect, and he had no doubt that Sir Moses' visit would produce much good.

They then had some conversation respecting the repeal of the Corn Laws in England, the Bill having passed by a majority of ninety-three. They also spoke of the death of an English Admiral, and our victories in India. Their parting was most friendly.

Sir Moses and Lady Montefiore then left cards on the Princess, all the Ministers, the Spiritual Head of the Hebrew community, and the representatives of the several institutions they had visited; and orders were given for their departure at three o'clock in the morning.

In the course of the day, Colonel du Plat called to bid us farewell. A great number of persons came in the evening for a similar purpose, and remained till one o'clock in the morning. Sir Moses then entrusted some of the gentlemen with his generous donations for the poor of all denominations, also for schools, hospitals, and charitable institutions; and, with the most favourable impressions of the good intentions of his brethren in Poland, we left Warsaw at the appointed hour.

On the same day, May 25th, we arrived at Posen. Wherever we had stopped on the road, even at the post-houses, where we could only remain for a few minutes to change horses, deputations with addresses awaited our arrival.

Early in the morning of Tuesday, a deputation from the Old Synagogue came to conduct Sir Moses and Lady Montefiore to divine service. The venerable edifice, which is very ancient, large, and of handsome proportions, was lighted up, and the paths leading to the seats strewn with flowers.
