The injection of INAH inhibited the development of the chick embryo, and the combination of SM further strengthened the inhibition. No malformation was recorded. The amount of the allantoic fluid tended to increase with the injection of SM, but to decrease with the injection of INAH. The excretion of INAH into the allantoic fluid increased as the amount of INAH administered increased. The amount of INAH excreted reached the maximum on the 15th day of incubation. When INAH was adiministered on the 5th day of incubation, the amount of INAH excreted was greater compared with that when INAH was administered prior to the incubation. The excretion of SM into the allantoic fluid was promoted by the combination with INAH.
