EXPLANATIONS OF FIGURES. 



FIG. 1. Section of the placenta of the pig showing the apposition of the chorion to the uterine mucosa. The chorionic 



epithelium and uterine mucosa contain numerous mitochondria. 

 FIG. 2. Section of a uterine gland from the pig's placenta showing mitochondria. 

 FIG. 3. Section of the placenta from a cat, nearly half term, showing the mitochondria in the endothelium of the 



maternal blood-vessels and in the chorionic epithelium. 



FIG. 4. Section of the placenta of the guinea-pig, showing abundance of mitochondria in the interlobular syncytium. 

 FIG. 5. Section of the placenta of the guinea-pig, showing mitochondria in the syncytium of the labyrinth. 

 FIG. 6. Section of villus from human placenta showing mitochondria in the syncytium.
