Abstract
Summary
(1) Dinitroplienol administered intragastrically twice daily, in 20 mg. per kg. of body weight did not appreciably affect the fertility of white rats. (2) This dosage of dinitrophenol in the presence of an unlimited diet did not appreciably affect the body weight gains of mothers during pregnancy. (3) Neither did it affect the average number of young horn to each mother. Rats given dinitrophenol intragastrically will bear about as many young per litter as control rats, but the number of stillbirths is increased 3% times over that of the control litters. (4) During the nursing period the mortality of the young of dinitrophenol-treated mothers was considerably greater than that of the young of control mothers.
