In 1797 much vapour and heat was emitted.

Other eruptions occurred in 1816 and 1820, and in 1824 a new crater is said to have been formed.

Yet so capricious is the action of these subterranean fires, that since the last-named epoch all eruptive symptoms have so completely ceased, that I was assured by many of the most intelligent European inhabitants of Amboyna, that they had never heard of any such thing as a volcano on the island.
During the few days that elapsed before I could make arrangements to visit the interior, I enjoyed myself much in the society of the two doctors, both amiable and well-educated men, and both enthusiastic entomologists, though obliged to increase their collections almost entirely by means of native collectors.

Dr.Doleschall studied chiefly the flies and spiders, but also collected butterflies and moths, and in his boxes I saw grand specimens of the emerald Ornithoptera priamus and the azure Papilio ulysses, with many more of the superb butterflies of this rich island.

Dr.Mohnike confined himself chiefly to the beetles, and had formed a magnificent collection during many years residence in Java, Sumatra, Borneo, Japan, and Amboyna.
