adds that the breadth is very constant in all the specimens, wher® 
the length presents slight variations from in. to in. (=abra 
15*3 to 20 mm.). In 1877, the parasite was recorded by MACGREGOi 
as the possible cause of a peculiar form of paralytic disease, of wind 
he had seen three fatal out of eight cases. The observations werenui 
in Port Louis, Mauritius, but all the patients were again Chinaae: 
I have at present no access to MACGREGOR'S original article, but tin 
parasites found and described by him were subsequently examined by 
COBBOLD and recognised as identical with those of McCoNKELL 
In 1878 McConnell himself describes a second case observed ; 
him in Calcutta ; “ the subject was, curiously enough, again a China 
man, and the distomata found " were quite identical with those 
originally found.” Comparing these earliest observations we see that 
m all cases the bearers had been Chinamen, and that the parasite 
must have been of about the same size for no allusion is made to the 
existence among them of any noticeably smaller individuals. 
hi 1883, die presence of flukes in the liver of Man was reports: 
from Japan, first in a paper written in Japanese (“ Observe 
Hons on Distomes in the Lung and Liver ") by KlYONO, NAKAHAHA 
Suc.a and Yamagata, acting physicians in the hospital of Okayama 
and a short time later by Baelz in a paper “ Ueber einige neue
