France in 1903, and a Loa was extracted from the eye in Janu- 

 ary, 1904. An intense cosinophilia was noted in 1903, and 

 though subject to fluctuations, continued after the removal of 

 the worm. Probably other parasites also were present. The 

 case is recorded by Wurtz et Clerc, 1904, 1905, and Kerr, 1904. 



75. Rev. S. O. K., from Yakusu on Upper Congo, where he 

 had been for three years, returned to England in January, 1904. 

 Localized swellings, chiefly on the left forearm, first appeared 

 after one year in Yakusu. Blood examinations showed micro- 

 filariae with diurnal periodicity well marked, hence diagnosed 

 as F. diurna. The case was sent by Dr. Habershon to Sir Pat- 

 rick Manson and described by Kerr (1904). 



76. In a European who suffered from these transient swell- 

 ings there was also a Filaria loa present and in the blood numer- 

 ous embryo filariae which could not be distinguished from 

 F. diurna. The case was observed by Dr. Hanley of Old Calabar 

 and published by Kerr, 1904. 



yy. From a native of Old Calabar a F. loa was removed and 

 found to be full of sheathed embryos indistinguishable from 

 F. diurna, which were also found in the blood. No mention is 

 made of swellings in this case by Dr. Hanley, whose account 

 was published by Kerr, 1904. 



78. At an autopsy of a Congo negro who died in Paris of 

 sleeping sickness, Penel (1904:207) found more than thirty adults 

 scattered through the superficial connective tissue of the four 

 appendages, and despite most careful search not a single speci- 

 men could be discovered in the neck, face, or region of the eye. 



79. In 1904 Looss published an account of the structure of 

 F. loa based on three specimens from the Gold Coast ; their 

 source is unknown. The}- represent at least one case of human 

 infection with this parasite. 



80. At an autopsy of a native in Kassai, Brumpt found among 

 other specimens encysted and so completely calcified as to be 

 unrecognizable, a fragment of a 'Filaria encysted in the heart, 

 which on return to France and comparison he identified as F. loa. 

 It was a female and -contained embryos identical with those in 

 the blood of the same host. The case is recorded in Brumpt, 

 1904.
