Le géologue anglais Daniel Sharpe envoie un catalogue de vente.

Envoi d'un catalogue de vent aux enchères. "I send you the catalogue of the sale of a number of works which may interest you. They belonged to a Gentleman who is just dead & are selling off by his exhibitors who are friends of mine [...]. There are one or two cases of birds, also but I haven't sent the rest of the catalogue but I should make my work not to heavy for the Post".
