and from the conditions found at the autopsy there can be no doubt 
that the patient died from a septic peritonitis due to the lesions caused 
by this worm. 
The worms taken from the cysts were sent to Professor Railliet, 
who most kindly volunteered to undertake the description of the 
parasite. 
The history of the disease is unknown, as the patient entered the 
public ward of the Santa Casa de Misericordia in Manaos in an 
extremely critical condition. He was admitted to the Hospital 
suffering from acute dysentery ; he became delirious, and died within 
three days. Our records describe him as a man, aet. circ. 36, a native 
of the Amazon State, Rio Purus region. 
The autopsy was performed ten hours after death. Unfortunately 
the case occurred at a time when there were many other duties to be 
performed, and consequently the post-mortem was incomplete.
