Arsenic content of various marine crustaceans and mollusca has drawn attension of CHAPMAN1) and that of marine algae, some food stuffs, or fishes of FEHLENBERG2) and SADOLIN3), who found that in fishes arsenic is more abunduntly distributed in oil fraction than any other tissues. HEFFTER and presented three hypothesis, that is Lecithine hypothesis, Nuclein hypothesis and Keratine hypothesis, with regard to the manner of combination of this element in tissues. HOLMES4) has recently reported that the arsenic content of codliver oil depends much upon its feeding of crustaceans.
In the present paper there are embodied arsenic contents of food-organisms for fish (I, II, and III) and the distribution of the element in water soluble part, ether soluble part and the residual tissues of pupae of silk warm. The estimation of arsenic was followed by I. BANG'S6) titration method.
For the results of experiments the reader is referred to Tables 1. and 2.
