Suggests that F. loa when in the eye has "lost its way" and its 

 proper habitat is some part more favorable for release of the 

 embryos into the general circulation. Queries whether the 

 smaller form, later called F. perstans, might not be the larva 

 of F. loa. Subsequently he assigned this role to the larger 

 species, now called F. diiirna.

Identical in the main with earlier edition, but adds discussion 

 on Calabar swellings.

 Med., 6:347-48. 



Records eight cases among rnissionaries, two coming under his 

 own observation. The peculiar geographic range, transient 

 character, irregular recurrence of these swellings, and asso- 

 ciation with F. loa, all point to a causal relation. Conjec- 

 tures the cause as the parturition of F. loa; failure to find 

 embryos due to time or incompleteness of observation.
