In the previous report1), the author pointed out that the contents of phosphorus compounds in the muscle of live fish were affected by ammonium ion, 7'P and CP being decreased while IP increased. The work described in the present paper was further undertaken to know the effect of urethan on the phosphorus compounds in fish muscle. The results obtained are summarized as follows: (1) Gibels became insensible to 0.5, 1.0 and 2.0% urethan solutions, after 2.5-3.0, 1.5 and 1.0min. of rearing in them, respectively. (2) The muscle of fish narcotized by 0.5, 1.0 and 2.0% urethan respectively contained 1.1-2.4, 3.9-6.3 and 3.9-5.4mg% of 7'P more than that of control. (3) There was remarkable difference in the post-mortem changes of 7'P and CP between the narcotized and control fish; namely fish narcotized by 1.0% urethan contained 0.5-15mg% of those compounds more than control in the course of 72 hours of storage at 0°C.
