later thought it had disappeared, as one was passed per rectum. 

 Eight months after her return a male was removed from one 

 eye by Dr. Robertson and reported by him (1894, 1895). From 

 the same patient he removed subsequently (1895:162) a female 

 worm. Further history of this patient is recorded in case 73. 



35. A woman who lived at Old Calabar from i860 to 1863 

 had suffered while there from a worm in the eye. After her 

 return she had a Loa removed in 1875 and a second in 1876. 

 The case is recorded by Robertson (1894, 1895). 



36-37. Dr. Thompstone, of Opobo in Nigeria, described two 

 cases of Loa in natives. One was in the lower eyelid, the other 

 beneath the conjunctiva. He was not able to remove either 

 worm. These data were published by Robertson (1894, 1895). 



38. In a woman at the same mission v/ith case 33, the worm 

 ivas seen to pass from one eye to the other over the bridge of 

 the nose. It was not removed. The case is recorded in Robert- 

 son (1895). 



39. A missionary in Old Calabar had a Loa which showed 

 itself at irregular intervals for about fifteen years and then disap- 

 peared without having been removed. Robertson (1895) gives 

 the record of the case. 



40. Dr. J, R. Logan, of Liverpool, removed a male Loa from 

 the eyelid of a patient. The blood of this patient was examined 

 for filariae but held none. This worm was examined and de- 

 scribed by Manson (Robertson, 1895). No further data are 

 given. 



41. A female F. loa was taken by a merchant from the eye of 

 a negro at Cayo (French Congo) and sent to Berlin. The case 

 was recorded and discussed by Hirschberg (1895). 



42. In 1895 Dr. Saemisch extracted a Loa from the eye of a 

 Russian marine officer who had been in Fernando Po from 1886 

 to 1891, and in Gaboon, Kamerun, and the Gold Coast from 1882 

 to 1885. The parasite was carefully described by Ludwig (Lud- 

 wig und Saemisch, 1895). 



43. In July, 1895, Roth observed an extremely active Loa in 

 the eyelid and just above it in a Jackrie girl at Warri, on the 

 coast of Nigeria. He failed in the efifort to remove it.
