ASCARIS LUMBRICOIDES. 311 



his ''Traite Pratique," publishes two cases of amaurosis in jo\mg 

 girls from lumbrici. 



Amongst fatal cases there is the one by Petrenz, where 200 

 lumbrici produced acute enteritis, and one by Kell, where the 

 intestine was perforated ; also two by Young, where the worms 

 were evacuated by ulceration through the parietes of the abdo- 

 men ; also Roger's fatal case of intestinal perforation reported in 

 the "Lancet" (1848); also Blair's case in the "Edinburgh 

 Medical Journal " (1861); also Mondiere's three cases of perforation 

 cited in the " Medical Chirurgical Review " (1839) ; also two others 

 by Buchner in the same journal (1851) ; and one by Luschka, 

 where the worms occupied the cavity of the pleura (1854). In 

 the same periodical (1833) Neilson has recorded a case of dis- 

 charge of lumbrici from various parts of the body, and much 

 more recently a successful case has been published by Sheppard, 

 who extracted an Ascaris lumhricoides from an abdominal abscess 

 (" British Medical Journal," for 1861). Amongst cases producing 

 irritation in the genito-urinary passages, is the one by Dreyfus, 

 recorded in the " London Medical Gazette " (1847), in which a 

 cure was effected by discharge of the worms, and the American 

 case by Buckingham, where the presence of Ascarides gave rise to 

 a formidable erotomania. 



In addition to the above I may mention that the third fasciculus 

 of a work illustrating the collection of morbid anatomy in the 

 Army Medical Museum at Chatham, gives a case of lumbrici 

 occupying the biliary ducts and gall bladder ; and I also find two 

 more anonymously-recorded cases of lumbrici producing perfora- 

 tion of the small intestine, one of them appearing in the *' London 

 Medical Gazette " (1827), and the other in the " Lancet " (1836). 

 But, perhaps, the most curious cases (which illustrate a remark- 

 able peculiarity of habit enjoyed by these parasites) which I have 

 met with are those severally described by Barwell, the Messrs. 

 Prichard, Stockbridge, andWilhams. In Barwell's case an Ascaris 

 was expelled a child who had accidentally swallowed a foreign body.
