I have had some sketches of it made by a competent artist, and these, as well as the preparation itself under the microscope, I have pleasure in exhibiting to you.

It appears to me not improbable that this specimen may be found to supply what has hitherto been a missing link, namely, the male animal.

Since writing this I have had the opportunity of submitting the specimen to Dr. Munson, who at once recognised it as the male worm, and has undertaken to make a careful microscopical examination and description of it.

Report by Dr. Manson on the structure of the Filaria loa, from an examination of the specimen removed in the foregoing case, as well as of the specimen of the same parasite exhibited at a meeting of the Society on January 31st, 1895. The latter filaria was removed from the eyelid of a patient by Dr. J. R. Logan, Liverpool.
