Tests on the growth of the eggs of Ancylostoma duodenale and Ancylostoma americanum were carried out by incubating them in the water, in the water contained in an anaerobic jar'and in the suspension of the feces, as well as by using polyethylene film method. The results are summarized as follows: (1) When the eggs of Ancylostoma duodenale were incubated in the water at 28℃ for 48 hours, 96.6 % of them developed into larvae; when incubated at 38℃ for 48 hours, 95.5 % of them developed into larvae, when the eggs of Ancylostoma americanum were incubated in the water at 28℃ for 48 hours, 92.3% of them developed into larvae; when incubated at 38℃ for 48 hours, 47.0% of them developed into larvae. (2) When the eggs of Ancylostoma duodenale were incubated at 28℃ for 24 hours by using polyethylene film method, 97.8 % of them developed into larvae; when incubated at 38℃ for 24 hours by using the same method, 98.6% of them developed into larvae. When the eggs of Ancylostoma americanum were incubated at 28℃ for 24 hours and 48 hours using polyethylene film method, 59.0 % and 81.0 % of them, respectively, developed into larvae; when incubated at 38℃ for 24 hours and 48 hours by using the same method, none of them developed into larvae. (3) When the eggs of Ancylostoma duodenale were incubated in the water contained in an anaerobic jar, very few of them developed into larvae. When they were incubated at 28℃, 98.5 % of them reached the embryonated stage; when incubated at 38℃, 55.1 % of them reached the embryonated stage. When the eggs of Ancylostoma americanum were incubated in the water contained in an anaerobic jar, none of them developed into larvae. When they were incubated at 28℃ and 38℃, 34.0% and 5.8% of them, respectively, reached the embryonated stage. (4) When the eggs of Ancylostoma americanum were incubated in the suspension of the feces at 25℃, 28℃ and 38℃, their development was prevented, none of them developing into larvea
