occasionally that they produce a sore or abscess, and I think that 

 is when, like the Guinea worm, they lay their eggs [embryos] or 

 multiply in a given locality. This last is only hearsay. 



"These cases came under my care incidentally and have never 

 been reported." 



From Dr. C. F. Friend, of Chicago, formerly a medical mis- 

 sionary of the Presbyterian Church in West Africa, I have been 

 the recipient of most courteous information regarding a case 

 hitherto unreported. Dr. Friend very kindly sent me the speci- 

 men in alcohol together with photomicrographs he made from 

 the living worm, and also drawings of the specimen. There is 

 no doubt as to the species, which is unquestionably F. loa. Re- 

 garding this case Dr. Friend says : 



"This is the only specimen that I have ever removed, and it is 

 that from Mrs. X.'s eye about four years after her return to 

 America. I am sorry to say that I have lost or misplaced the 

 notes made at that time or I would send them with this letter. 



"While I have not removed a Loa from any part of the body 

 other than the eye, yet I have thought that it did travel to other 

 parts, for at different times both Mrs. X. and myself have seen 

 what appeared to be the movement of the worm in different 

 regions of her body. And I have thought that swellings which 

 appear at times on her hands or arm and a time or two on her 

 thigh were caused by the Loa, as she would have the sensation 

 as of the movement of the worm prior to the swelling, but not 

 always so. In fact, at times when we thought we saw the worm 

 in the parts referred to there would be no swelling, and again 

 when I have cut down upon the part when we thought we saw 

 it, we did not find the Loa. On the other hand, I think Dr. Love- 

 land did remove a Loa from under the skin of the back of Mrs. 

 R. about 1890. The specimen I am sending you was removed 

 early one morning from under the conjunctiva of the left eye 

 near the outer canthus. 



"The night before Mrs. X. had complained of a sharp, piercing, 

 pricking sensation, or pain in the eye, which from previous ex- 

 perience she knew to be the movement of the worm, but I could
