Abstract
Barklay, Haas, Huggett, King and Rowley1 estimated the fœtal fluids of the sheep between the 49–140th day of gestation for total reducing substances by copper reduction and for fructose by resorcinol. The glucose concentration was taken as the difference between these two values. The mean values were 61 mg and 150 mg/100 ml. for the amniotic and allantoic fluids respectively; for fructose both allantoic and amniotic fluids had mean values of 195 mg/100 ml. Re-examination of the fœtal fluids using the specific glucose oxidase method of Huggett and Nixon2 has revealed that, in fact, the concentration of glucose is extremely small and in some cases absent.
