Thanks for turkey. Compliments Smith on new part of "Flora Graeca" especially 'Dianthi' ['Dianthus'?]. [Samuel Goodenough] and himself agree with Smith on [Robert] Brown, who is making up his mind on an unspecified subject. Asks after Smith's "intersting "Flora"". Received letter from [Alexander von] Humboldt who is working on his "Geography of Plants" and complains of [Aimé] Bonpland having taken specimens. Has just obtained first part of a "Flora of Brazil".
