Abstract
1. Polysaccharide and pro t ein in liver cells of Oryzias latipes, which were kept in the water of room temperature, of 0°C. and of 31-32°C., were examined.
2. Polysaccha r ide decreases to some extent in the low temperature experiment, and diminishes markedly in the high temperature experi ment.
3. In the low temperature experiment, a change of protein in nucleus is scarcely realized, whereas the amount of protein in cytoplasm decreases.
In the high temperature experiment, the amount of protein increases in nucleus and decreases in cytoplasm.
