Sensitivity to odours in the embryo of the domestic fowl was investigated on the day before hatching. Embryos were tested with four odorants: dichloroethane, cineole, amyl acetate and formic acid. Three odorants (dichloroethane, formic acid and cineole) produced an increase in the heart rate and a rise in the rates of beak-clapping and the first two increased the amount of head-shaking. Odorants had little effect on other types of activity. The response to amyl acetate varied between experiments. Blocking the nostrils with wax abolished the response. Some implications of these results are discussed briefly.
在孵化前一天对家鸡胚胎的气味敏感性进行了研究。用四种气味剂对胚胎进行测试：二氯乙烷、桉叶油素、乙酸戊酯和甲酸。三种气味剂（二氯乙烷、甲酸和桉叶油素）使心率加快，啄喙率上升，前两种还增加了摇头次数。气味剂对其他类型的活动影响很小。乙酸戊酯的反应在不同实验中有所不同。用蜡堵塞鼻孔可消除反应。简要讨论了这些结果的一些意义。
