Postpones their meeting; surprised Smith is already thinking of returning to London. Glad Smith is named editor of [John] Sibthorp's "Flora Graeca"; it will give Sibthorp more credit; Smith has the notes from his examination of Tournefort's herbarium at Paris; and will add an "additional leaf" to Smith's "wreath, already sufficiently full". Poor health of Smith's sister, Fanny, and sister-in-law, [Mrs Frederick Smith]. Thanks for parcel from [William] Withering, which contained seed of 'Bromus diandrus', which could become a valuable grass to sow for sheep pasture; 'Anthoxanthum verna' has similar properties; asks if Smith knows anyone willing to experiment with 'Poa annua' for same end.
