We had the pleasure of listening to this celebrated cantatrice last evening, at Neil's New Hall. We have only three things to say of her performance. The first is, that she was honoured with a crowded house, composed of the most intelligent and enlightened of our citizens: second, that all who heard her were exceedingly well pleased with all her efforts; and third, that notwithstanding it is not claimed, either by herself or friends, that she is an artistic singer, yet the compass of her voice has rarely been equalled, and the sweetness of her notes seemed to enchant every auditor. Philadelphia, March 16th. TO ELIZABETH GREENFIELD:-- Thy letter from Columbus came safely to hand, and it gave me pleasure to hear thee is doing so well; and I hope it may continue until thy return to our city. In answer to thy inquiry about my parents, I am glad to say they are both enjoying good health. Father is still busy by times, with the old lady's estate, but it does not, as yet, seem to be near a final settlement. It is true that Mr. Richards has received her money, as it was for services rendered to aunt Betsey--not from having been left any thing in the will. But all the legatees, of which thee is one, will have to wait until the whole business is concluded. It has been very trying and tedious to all concerned; but I hope, ere long, the right thing will be brought about, and thee will then receive what is thy due. Judge Jones has been appointed in J. Bouvier's place--is an able and excellent man, and will no doubt do all he can to hasten the settlement of the whole affair. Thy friend, D. T. HOWELL. American House, March 5th, 1852. EDITOR OF THE REPUBLIC:-- We have been favoured this afternoon, together with some ladies, with a private musical entertainment by Miss E. T. Greenfield, known as the "Black Swan"--and words would fail us to do her voice justice, even were she _white_. Never having heard the renowned Madame Goldschmidt, we can draw no comparison between the Swan and her fairer Swedish rival; but however she may compare with her, allow us to say she has the most varied and powerful voice it has yet been our fortune to hear. She gave us first the arietta, "Where are now the Hopes I've cherished?" accompanying her voice with the guitar--which, as well as the harp and piano, she uses very skilfully. This song, though easy of execution, is charmingly sweet and plaintive--and how it could be better performed than upon this occasion, it is difficult to imagine. Every heart present was thrilled with her tones, which flowed from her lips like gems.
