When any one is ill they say it is the demon tormenting him, and keep up night and day a frightful uproar round him, which only ceases when one of the bystanders falls as in a fit, crying out, “He has passed into me, he is stifling me.” They then question the new patient as to the remedies which must be employed to cure the sick man, and as to what the demon demands to abandon his prey. Sometimes it is an ox, a pig, too often a human victim; in the latter case they pitilessly seize on some poor slave, and immolate him without remorse.

They imagine that all white people inhabit secluded corners of the earth in the midst of the sea, and often ask if there are any women in our country. When and how I can return to Cambodia and Siam I am ignorant, and I dare not think of the difficulty I shall experience among the rude and stupid Cambodians in transporting my treasures. What heartbreaking jolts my boxes of insects will receive! What palpitations I shall feel each time some rough fellow takes them to place on the oxen, elephants, or his own back! Poor soldiers of science! these are our trophies, and in the eyes of some people find as much merit as a piece of silk fastened to a pole; and what pains, patience, and solicitude is necessary to procure them! therefore I believe my anxiety as to my collections will be understood by the lovers of nature.

Pinhalú, 20th December, 1859.

P.S.—I arrived last evening at Pinhalú, in perfect health, and am now about to go northward to visit the famous ruins of Ongcor and then return to Bangkok, so I have little time to give you any details as to what I despatch from Komput and Singapore. I am not quite satisfied; for birds are scarce here, and I have but a small number; besides, my boxes as I feared have been much knocked about; I sent them off to Komput on men’s backs. On my return to Bangkok I will send you some good maps of this almost unknown country.

Khao Samoune, Province of Pechaburi (Siam). Lat. N. 13° 4′, long. 100°. 15th June, 1860.

In my last letter, of March, 1859, I told you about two active volcanoes that I discovered in the Gulf of Siam, one in the little isle of Koman, lat. 12° 30′ 29″ N., and long. 101° 50′ 2″ W., mer. of Greenwich, and of the probable existence of others whose workings were latent and slow. Since then I have travelled through Cambodia, from north to south and from east to west, gone up the Mekon as far as the frontier of Laos, visited one of the savage tribes which live between these two countries and Cochin China, then crossed the great lake Touli Sap, explored the provinces of Ongcor and Battambong, which are full of splendid ruins, one of which in particular, the temple of Ongcor, is almost perfect, and, perhaps, unequalled in the world. I then passed from the Mekon to the Menam, and returned to Bangkok.

A low table-land, of which the gradual slope takes a week to ascend, separates the two rivers.
