IN MEMORY 
of 
Prof. Dr. MELCHIOR TREUB, 
late Director of the Botanical Gardens at Buitenzorg and of the 
Department of Agriculttire in Dutch East India. 
The first volume of this work was by its contents an “in memoriam” 
of P. BLEEKER, who has done more than any man to promote our 
knowledge of the ichthyology of the Indo-Australian Archipelago. 
This second volume, the first of a series which describes the fishes 
of that Archipelago, is dedicated to the late Prof. MELCHIOR TREUB. 
More than any one else he has promoted scientific life in Netherlands 
India and has succesfully taught, that science is the base also of 
practical colonial enterprise. He knew that scientific exploration of the 
unknown fields of a colony is a charter of their possession, and he 
accordingly promoted their exploration. His last official act was to 
procure governmental aid for this present work; may it be a slight 
token of our esteem for his everlasting labors.
