Filaria loa 17 



44-45. Later the same author (Roth, 1896) observed similar 

 worms in two other natives without being able to extract them. 

 He believed they passed out through the nasal duct. In spite of 

 their frequence a reward failed to secure specimens. 



46. In 1893 Barrett removed a worm from the eye of a young 

 white man who had lived on the Gold Coast but had left there 

 four years before arid since then had resided in Melbourne ; it 

 was the first specimen removed in Australia. The worm was 

 examined by Professor Dendy and determined as Filaria ocu^i 

 Jnniiaiii. Barrett reported the case in 1896. 



47-49. In three natives of Kamerun Dr. Plehn observed spec- 

 imens of Loa in the eye. He attributed to the worm also the 

 variable cutaneous inflammations found on the West Coast of 

 Africa, and discussed them at length (Plehn, 1898). 



50. In an English official Plehn also knew of a case, although 

 he did not see the worm himself. According- to the natives this 

 worm occurs also in the eye in goats and sheep. He records 

 these facts in the paper cited above (Plehn, 1898). 



51. A French missionary who spent 1894-96 on the Ogooue in 

 French Congo was relieved of a male F. loa by Dr. Bernard in 

 1898 at Paris. Bernard described the case (1898) and sent th;- 

 specimen to Blanchard for study. This was in fact the second 

 specimen taken from the same host ; the first was described later 

 (see case 52). 



52. Dr. Leneveu removed a female Loa from the same host in 

 August, 1897. The case is recorded by Blanchard (1899), w^ho 

 also gives an extended account of the anatomy of the two 

 specimens. 



53. Manson had a negro patient under his care in whose blood 

 F. diiiriia abounded. When a lad he had a Loa in his eye. The 

 case is recorded in Manson, 1893. 



54. A lady long resident in Old Calabar had a Loa extracted 

 from under the skin over the right clavicle. She informed Man- 

 son (cf. Manson, 1900:562) that if rubbing or scratching is not 

 indulged in when a Loa approaches the surface there will be no 

 swelling, and that Calabar swellings are produced by the rubbing 

 solicited bv the irritation caused bv F. loa.
