Since the above was written, a second Chinese case of schistosomiasis has been 
recorded by Bayer (Amer. Med. (1905), X, 578). This case was first observed by 
O. T, Logan, of Changteh, Hunan, China, who made clinical notes upon the ease 
and who later sent these and specimens of the faeces to the Naval Medical School. 
The patient, a boy of 18 years, for six years had bloody stools. At 15 years of 
age he had been incapacitated for hard work. Logan found the liver and spleen 
enlarged, the latter but slightly. The stools, which continued to show blood, 
averaged about four in twenty-four hours and were preceded by abdominal pain. 
The ova of the parasite were found in the feces, and each ovum contained a 
ciliated embryo. Logan thought the ova were those of SN. japonicum, and in this 
view Stiles, Lovering, and Beyer coincide.
