lie upon the gyri, while others are deep in the sulci. On the left hemi- 

 sphere, one is found on the superior frontal, one on the middle frontal, 

 one on the posterior central gyrus, one on the temporal pole, two on 

 the middle temporal gyrus, one on the external surface of the occipital 

 lobe, near the anterior end of the occipito-temporal gyrus, and one on 

 the precuneus. On the right hemisphere one is found on the inferior 

 frontal, two on the inferior temporal, one in the collateral sulcus, and 

 one in the lateral occipital sulcus. There is one also on the right pre- 

 cuneus. On section of the brain, one is found on the left lateral wall 

 of the third ventricle, projecting slightly into its lumen. The lateral ven- 

 tricles are not dilated; the cerebrospinal fluid is clear. On section of the 

 basal ganglia one cyst is found in the lower lateral portion of the right 

 thalamus and one in the head of the right caudate nucleus. On removing 

 the hypophysis, a small cyst similar in appearance to those of the brain 

 but containing soft, gelatinous material is found on its inferior surface. 



ADDENDUM 



Closer inspection of a number of the cysts reveals the following: 

 Near the middle is seen a white spot which, on opening the cyst, is 

 seen to correspond with a small rounded mass projecting from one side 

 into the lumen. Under the microscope this projection resembles the head 

 of a tapeworm. There are 4 suckers beyond which is a circular row of 

 booklets, 26 in number. 



CLONORCHIS 



Two cases have occurred in which liver flukes were found. 

 In the first case they were present in the cystic, common, and 

 intrahepatic bile ducts of a 27-year-old Chinaman who died of 

 an acute dilatation of the heart, complicating chronic nephritis. 



The second case in which they occurred was also a China- 

 man, 29 years of age, who had died as the result of a perforation 

 of the intestine in the course of typhoid fever. In this case they 

 were found only in the intrahepatic bile ducts. In neither case 

 did the bile ducts or liver show any changes attributable to the 

 presence of the parasites. 



The flukes in both cases have been identified by Doctor Willets 

 of the Bureau of Science as Clonorchis sinensis Cobbold, 1875. 



The identification is based upon the presence of dark-brown, granular 

 pigment in the body parenchyma and the excretory apparatus and the 

 following anatomical characters: 



Size and shape. — Flat; elongated, 18 by 3.5 millimeters; another, 18 by 4 

 millimeters. 



Cuticular spines. — Absent. 



Anterior ewd.— Rather pointed. Head cone absent. 



Oral sucker. — Small. 



Acetabulum. — Small; well developed; near oral sucker. 



Pharynx. — Small; well developed. 



(Esophagus. — Rather short. 



Intestinal cieca. — Unbranched; extending to near the posterior extremity 

 of the body.
