Tendency of the motility is the same in either case of nicotine loading made on fertilized eggs before incubation or on the 5th day after starting incubation. Appearance of deformity is recognized on the eggs loaded with nicotine more than 1.0 mg. When viewed from the stand-point of the amount of deprotenized nitrogen in allantoic fluid, the influence of nicotine loading can evidently be recognized from 1/10 of the above mentioned dosage influencing the development of chick embryos.
Appearance of nicotine hydrops is not recognized on the eggs of the 9th day incubation, but it appears most remarkably on the eggs of the 12th day incubation, gradually decreasing thereafter.
