The authors purified the Fugu poison and the following results were obtained:
1. In the purified poison the amount of total nitrogen agrees with that of amino-nitrogen.
2. When the poison is heated at the alkaline reaction, ammonia is generated, and its nitrogen corresponds to 30% of the total nitrogen.
3. Some tests on the poison were described.
In conclusion, the authors are greatly indebted to Prof. K. Kodama for his kind criticisms and suggestions throughout this research.
