hour chick embryos. He exposed 48 hour embryos to 1.0 mg of nicotine for several days. The results conclude that there was a high incidence of embryonic death and developmental defects (Gilani 1986).

In our research, we wanted to expand on Gilani's chick experiments and discover the effects of nicotine on the chick embryo. The objective of our research was to try to answer three specific questions. First, does nicotine inhibit the absorption of calcium in chicks and result in suppression of bone growth? Second, does nicotine cause a retardation in development? Lastly, does the addition of nicotine result in an increase in heart rate?
