216 PARASITES OF MAN 



localities, that the Anchylostomes, if duly sought for, will be 

 found in many other countries." 



These details given by Wucherer are so precise and instructive 

 that I could not have further abridged them without injustice 

 to his record. The bearing of the foregoing facts in relation 

 to the question as to how we may hope to arrest the fatal action 

 of many of these nematodes is sufficiently obvious. That 

 strongyles and their allies prove highly destructive to man and 

 beast is as well established as any other recognised conclusion 

 in medical science ; nevertheless, there are those who still doubt 

 the power of these nematodes in relation to the production of 

 fatal epidemics. I shall deal with the sanitary bearings of the 

 subject hereafter. In conclusion, I may mention that Dr da 

 Silva Lima has forwarded specimens of Anchylostomum to the 

 Hunterian Museum, where they may be seen.

Dracunculus medinensis, Cobbold. This parasite is popu- 

 larly known as the guinea-worm, or Medina-worm. Pro- 

 bably Lister was the first writer who distinctly spoke of it 

 as the Dracunculus, 1690, the same title being applied to it by 

 Kaempfer, 1694. Be that as it may, Gmelin, long afterwards, 

 placed the parasite in the genus Filaria, at the same time 

 adopting the specific title medinensis. This had been pre- 

 viously employed by Linneus, who, however, regarded the worm 

 as belonging to the genus Gordius. It being clear from the 

 distinctive characters of the entozoon that it was desirable to 

 separate it from the Filariae, and that no better generic name
