LIFE-HISTOEY OF riLAETA BAKCEOPTT. 859 



as Indicating to me the lengtli of the worm, I now Incline to the 

 opinion that the worms In question were none other than sexually 

 mature examples of Filaria hancrofti. This view, moreover, 

 receives strength from the circumstance that 1 drew long thread- 

 like strokes on paper which, she said, corresponded In appearance 

 with the worms. As to the thickness of the worms, nothing 

 reliable was said. When I wrote the original paper I had no 

 knowledge of the fact that Wucherer had anticipated Salisbury's 

 previous discovery by about two years. 



In and about the year 1872 several ' finds ' of a similar order 

 to those above announced were made In foreign countries. I 

 regret that I cannot fix the dates of all these verifications with 

 absolute precision. In September 1872 Dr. Corre published a 

 " Note respecting the helminth encountered in haematochylous 

 urine " (Hef. No. 5). His careful description clearly refers to 

 the same entozoon as that already described by Wucherer, by 

 Salisbury, and by myself. Again, In a communication addressed 

 to Dr. Davaine, and quoted in the recently published 2nd edition 

 of his (Davaine's) well-known work, Dr. J. Crevaux refers to a 

 hsematurla patient of his, at Gruadeloupe, from whpse urine he 

 had frequently obtained small worms (vers de la Guadeloupe). 

 He had, however, more than a hundred times punctured his 

 patient for the purpose of examining fresh blood ; but in no single 

 instance did he detect microscopic Hsematozoa (Eef. No. 6). 

 If I understand rightly, Corre's description refers to worms ob- 

 tained from this selfsame patient. 



In Dr. Crevaux's remarks especial reference Is made to a joint 

 memoir previously published by Dr. da Silva Lima and himself 

 (Eef. No. 7). Dr. Crevaux adds that although Dr. Lima dili- 

 gently sought for haematozoa in five separate patients whose 

 urine contained numerous worms, yet In no instance were any 

 entozoa found in the blood. Notwithstanding the recorded 

 difierences as between the " vers de la Guadeloupe ^^ described by 

 Crevaux and Corre and the "vers du BresiP' described by 

 Wucherer and SIlva-LIma, I can see no valid reason for sup- 

 posing that they are not Identical forms. 



In this place must also be noticed a very Interesting circum- 

 stance recorded by Eobin (Ref No. 8). He says that Dr. Eon- 

 cervines transmitted to him the history of a case of chyluria 

 aifecting an officer residing at Eeunion Island. In this case some 

 blood-clots taken from the urine were found to contain embryonic
