Previously to calling on Lady Bentham I had accepted an invitation to dine this evening with Captain Gordon, a retired officer of the British army residing here, a friend of the Bentham family, who, hearing from Lady Bentham and Delile that I was soon expected here, called par hasard at the Hôtel du Midi, to request that they would send him word when I arrived. On finding me he insisted on my dining with him this evening. I have this moment, while I was writing, received a note from Lady Bentham, asking me to call on her this morning, saying she has a collection of plants made by herself for her son George at some interesting locality among the mountains, a set of which she is to have ready for me, knowing, as she says, that George would surely offer them to me. Although I had arranged my time a little differently, of course I shall call immediately after breakfast. Lady B., who is now very aged, is evidently a very superior woman; she is a very good botanist also, therefore, as I do not know the plants of the south of Europe very well, I am a little afraid of her. Marseilles, April 25, Thursday evening.--I broke off my narrative on Tuesday morning, two days ago. I must continue my brief account, and then close my letters to send from this port. After breakfast, Captain Gordon called on me, and we went together to Lady Bentham. We found his dinner hour so late that we were obliged to give up the expectation of returning to take tea with the ladies here. Delile joined us, and soon after I went with him to see the museum of painting and sculpture, which, by a curious circumstance, is the richest in France, except that of Paris. There are not a few of originals of great masters; two or three Raphaels; as many of Salvator Rosa, Rubens, Poussin, Carlo Dolci, etc., many of which I know from engravings. We went next to the Medical School, which occupies the former palace of the archbishop, who was ousted at the time of the revolution. This is one of the oldest medical schools, and for a long time very celebrated. It is declining now; they have no professor of very great talent at present, except Lallemand. I was shown the gallery of portraits of the professors from the commencement almost, a prodigious number, and some of the old fellows very queer to look at. I saw also the library, the collection of manuscripts, classical, theological, a few Persian, Arabic, etc., which fell into their hands some years ago. Thence we went to the Garden, looked at plants, but did not get on very much, Delile being fonder of telling long stories, complaining all the while how much he is pressed by his avocations, than of working hard. I then arranged my baggage, took a place in the diligence for Marseilles, called again on Lady Bentham, to take leave; dined with Captain Gordon, returned, and went to bed.
