Thanks for Smith's letter, just received; will be glad to have Smith's criticisms on the "Tab[ula] Syst[ematica]", as in addition to Smith's own practical botanical knowledge he has assistance of [John] Sibthorp herbarium. His hopes for future usefulness of his "Illustrationes Theophrasti". Sorry he is to miss Linnean Society anniversary meeting, hopes Smith may visit him near Liverpool in August.
