On 24 July, Thursday, we again waited on the apothecary Petiver, who at last showed us his natural curiosities. There is no need to speak much of them here, for there is a printed description of his museum with copper engravings. As soon as he obtains a fresh specimen he immediately has a copper engraving of it made and dedicates it in English fashion (for each copper engraving in a volume is dedicated to a different person, as you can see in Listreo de Conchyliis, Willugbejo and other works) to some compatriot or stranger, who is forced to give him a couple of guineas for it, as Dr Karger and others who have been thus incommoded complained. Petiver has nevertheless some handsome specimens of conchyliis and insectis, but they are far from being as perfect, clean and well arranged as those one sees at Vincenz's or elsewhere in Holland. The best thing he has is a handsome collection of plants, which entirely fill twelve thick volumes, which he showed us. One contained Spanish plants, which he had just received. But I have been assured that many complaints have been made concerning this Petiver; they say that he has the charge of the Hortum medicum of the apothecaries but treats it right scurvily, allowing no plants to multiply but either sticking them into his books or sending them away in exchange for others.
