April 30th. — I called on Lamb and accompanied him to Mr. Monkhouse, Queen Anne Street East. Haydon and Allston, painters, were there, and two other gentlemen, whose names I did not collect. The conversation was very lively and agreeable. Allston has a mild manner, a soft voice, and a sentimental air with him — not at all Yankeeish; but his conversation does not indicate the talent displayed in his paintings. There is a warmth and vigour about Haydon, indicating youthful confidence, often the concomitant of talents and genius, which he is said to possess. His conversation is certainly interesting. Monkhouse himself is a gentlemanly, sensible man. Lamb, without talking much, talked his best. I enjoyed the evening.
