Filaria loa 13 



removing the worms. The account of these cases was first pub- 

 Hshed by Arrachart (1805:228, observations 7 ff.) and later by 

 Rayer (1843). Guyot wds the first to view this species as dif- 

 ferent from the Guinea worm. He says : *'Je ne crois pas que 

 ces vers soient de I'espece du dragoneau, car ils sort tres blancs, 

 plus dur et mois longs a proportion. Je ne jamais vu ce ver se 

 faire jour de lui-meme. Pendant sept voyages que j'ai fait a la 

 cote d' Angola, je n'ai vu aucun negre attaque du dragoneau. 

 Plusiers chirurgiens qui ont navigue sur ces cotes m'ont assure 

 n'en avoir jamais vu." 



13. M. de Lassus, army health officer of St. Domingo, re- 

 moved a worm from the eye of a negro. The case is chronicled 

 by Larry, 181 2. 



14. In 1828 a worm was seen in the orbit of a negress, re- 

 cently arrived as a slave from Africa at Monpox, a village on 

 the banks of the Magdalena river in United States of Columbia. 

 This observation is attributed unmistakably by the original text 

 to Clot-Bey, a French surgeon, well known for his work in Egypt 

 about that date. The French authors agree in pronouncing this 

 authorship an error and in substituting the name of Roulin. I 

 have found neither explanation nor reference to Roulin or his 

 works. 



15. Dr. Blot, a physician on Martinique, in 1837 removed two 

 filariae from the eye of a young negress who had come from the 

 African Coast. One was sent to Guyon and Blainville, and 

 described by the former (Guyon, 1838). 



16-17. Loney, an English naval surgeon, in April and June, 

 1842, extracted moving worms from beneath the conjunctiva of 

 two Kroomen on the West Coast of Africa. He reported these 

 cases together in 1844. 



18. Lallemant excised a worm from the eye of a negro in Rio 

 de Janeiro, and in 1844 published a description of the case. 



19. In 1833 Christovo Jose dos Santos removed a worm from 

 the orbit of a Mina negress. Sigaud witnessed the operation and 

 reported it in 1844. 



20. Lestrille in 1854 removed a wonn from the eye of a negro 

 at Gaboon ; his description of the case was published by Gervais 

 et Van Beneden (1859).
