NEMATODA 191 



several distinct morbid conditions. To one of these Bancroft 

 has given a separate name (Helminthoma elastica). This is a 

 highly elastic form of growth to which I have already alluded 

 under the title of " lymphatic abscess of the arm." In the 

 first valuable report on Haematozoa, by Dr Patrick Manson, of 

 Amoy, China, this careful observer gives interesting particulars 

 of no less than fifteen cases in which hsematozoa were found. 

 Two of these patients had Elephantiasis scroti, two had lymph- 

 scrotum, two were lepers (one having scrotal disease), two had 

 enlarged inguinal glands, one had anasarca; and of the remain- 

 ing six, spoken of as having no concomitant disease, one had 

 enlarged glands and abscesses, and another suffered from 

 marked debility. It would thus appear that what is ordi- 

 narily termed " good health " is rarely associated with a haema- 

 tozoal condition of the blood in the human subject. The 

 cases given by Lewis and Manson, where absolutely no recog- 

 nisable disease existed, must be regarded as exceptional. Dis- 

 ease, moreover, may exist without any palpable symptoms being 

 exhibited by the f( bearer," and thus perhaps it was with the 

 hsematozoal dogs of Gruby and Delafond to which I shall again 

 have occasion to allude. Even those animals that carried 

 upwards of two hundred thousand microscopic Filarise in their 

 blood appeared to suffer no inconvenience whatever. 



In the autumn of 1877 Dr Da Silva Lima published an 

 article in the ' Grazeta Medica da Bahia/ in which he dwelt 

 upon the labors and merits of Wucherer, and, judging from an 

 omission in one of my memoirs, he supposed that I had insuffi- 

 ciently acknowledged Wucherer's claims. A translation of 

 this article appeared in the ' Archives de Medicine Navale/ 

 with an important appendix by Dr le Eoy de Mericourt. In 

 this addendum the French savant showed that the omission on 

 my part was unintentional, and had been corrected by me in a 

 later memoir. Not only had I been amongst the earliest in 

 England to enforce Wucherer's claims in respect of the micro- 

 Filarise, but I had first announced his discoveries in connection 

 with Anchylostoma duodenale. In my translation of Wucherer's 

 memoir (' Ueber die Anchylostomum Krankheit ') I spoke of the 

 melancholy satisfaction I had in knowing that the memoir in 

 question was " among the last that appeared from the pen of 

 that gifted and amiable physician." Some notice of Dr Lima's 

 paper and its appendix by Dr A. le Eoy de Mericourt appeared 

 in the ' Lancet ' for Jan. 5th, 1878, and I also published a full
