confined to what is known as the low veldt in South Africa. I have not 
found lateral spined ova in natives coming from other than tropical or 
semi-tropical parts. There is too the marked difference in the severity 
of the general symptoms of the disease in the two localities. 
To demonstrate approximately the number of times the terminal 
spined ova were produced as compared with the lateral spined ones, and 
also to ascertain in what proportion of cases both kinds of ova could be 
found in the same person, I made a careful microscopical examination 
of scrapings taken from the mucous membrane of the bladders and large 
intestines obtained at 90 consecutive autopsies. These examinations 
were conducted with special care, and I think the results given in the 
following Table III may be relied on absolutely.

* A few separate organs escaped microscopical examination for unavoidable reasons ; 
the numbers so escaping have been noted in a special column. 
In four of the above cases, namely, two Angonis, one Shangaan, and one Quilimane 
native, lateral spined ova were found in the mucous membrane of intestine but no ova 
could be found in the bladder. In only nine cases was the Bilharzia ovum absent in all 
organs. One Mozambique native gave negative results in the bladder and intestine but a 
single Bilharzia worm was found in the liver. The numbers of terminal spined ova found 
in mucous membrane of the large intestine were usually very few.
