Annoyed that the second edition of his "Nereis Britannica" was not presented to the Linnean Society, generally dissatisfied with the work but hopes it may inspire others. Surprised by [Dawson] Turner's abrupt conclusion to the "Hist. Fucorum". Received Lamoureux's essay on "Thalapiophytes", a complete arrangement of sea plants by order, published in "Annals du Museum National". Offers to send it to Smith as he believes that with the section on 'Filicus' in the last edition of Gmelin's "Systema [naturae]" it will simplify Smith's work for his "Flora". Has copies to sell of Lamoureux's "Histoire des Polypiers Coralligenus flexibles".
