On his return he went to the Sula Islands, and made a very interesting collection which served to determine the limits of the zoological group of Celebes, as already explained in my chapter on the natural history of that island.

His next journey was to Flores and Solor, where he obtained some valuable materials, which I have used in my chapter on the natural history of the Timor group.

He afterwards went to Coti on the east coast of Borneo, from which place I was very anxious to obtain collections, as it is a quite new locality as far as possible from Sarawak, and I had heard very good accounts of it.

On his return thence to Sourabaya in Java, he was to have gone to the entirely unknown Sumba or Sandal-wood Island.

Most unfortunately, however, he was seized with a terrible fever on his arrival at Coti, and, after lying there some weeks, was taken to Singapore in a very bad condition, where he arrived after I had left for England.
