The land and fresh-water shells are also very beautiful. Among the former there are twenty-five different genera; eight or ten are quite new, and some of them very remarkable. They will shortly be described by Dr. Pfeiffer and others. I can truly say that the insects and shells equal, if they do not surpass, the most beautiful collections I have ever received; and clearly demonstrate how rich a country for the naturalist lies between Siam and Cochin China. There is also a small collection of birds and some monkeys, small animals, reptiles, and serpents in spirits, of which some are quite new. The collection of insects and shells made in Cambodia was also very beautiful, and contained the large and fine _Helix Cambojiensis_, one of the best and most beautiful specimens known; also, the _Bulimus Cambojiensis_, and a splendid _Buprestida_, new and unique, besides a great number of others, new to science.[13] [13] M. Mouhot, in his letters to his family, always spoke with the highest esteem of Mr. Stevens, to whom they now beg to offer their thanks for the honourable manner in which he has conducted everything connected with their unfortunate relative. FROM M. MALHERBE TO M. CHARLES MOUHOT. Bangkok, Nov. 1862. DEAR SIR, On my return from Java a few days ago, I found waiting for me your kind letter, for which I thank you, although I should have wished to make your acquaintance under happier circumstances. All consolation from me, I know, would be ineffectual. The friendship I felt for your brother was not that of a stranger, but rather as though he were a member of my family; and I felt most painfully the news which met me on my return, of his death so far away: for I had been pleasing myself with the idea of his return, and long before my arrival here had given orders for his reception, and that he should be welcomed as though I were present. One great consolation to the survivors is the feeling of how much he is regretted; here he had not a single enemy, but every one spoke of him as the best of men. I vainly tried to dissuade him from undertaking this dangerous expedition, for I had already lost a dear friend in that country. He was treacherously assassinated there by his boatmen. I am much pleased with the frank manner in which you offer me your friendship. I thank you, and accept it with all my heart. PAPER READ AT THE ROYAL GEOGRAPHICAL SOCIETY, 10TH MARCH, 1862. LORD ASHBURTON, PRESIDENT. M. Mouhot traversed Cambodia from east to west, and also ascended the Mekon river to the frontier of Laos. He returned to the coast by crossing the water-parting between it and the basin of the Menam river, and descending to Bangkok.
