Pathological Effects of Filaria volvulus. 
One of the most interesting features in the natural history of 
F. volvulus is the formation of subcutaneous fibroid tumours which vary 
in size from a split pea to a hen’s egg. Clinically they are somewhat 
suggestive of dermoid tumours at first sight, being freely moveable over 
the subjacent tissues, while they are more or less firmly attached to the 
overlying skin. In older tumours, however, there may be very little 
mobility, and in one of my cases the growth was tightly adherent to the 
iliac crest. Apparently these tumours give rise to no symptoms, local 
or general; also, they must be very chronic in character judging from 
what I have gathered from the subjects of the disease. In my 
experience suppuration never occurs and Fiilleborn has come to the 
same conclusion. As regards the position of the tumours Fiilleborn 
(1908), quoting Zupitza, states that no part of the body is exempt, and 
they have been noted in such regions as the scalp, the chest wall, and 
the gluteal parts. 
It is interesting to note that the observations of Kulz (cited by 
Fiilleborn, 1908) are in accordance with mine in determining the
