ASCARIS LUMBRICOIDKS. 311 



his "Traite Pratique," publishes two cases of amaurosis in young- 

 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 bUiary 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, and Wilhams. In Barwell' s case an Ascaris 

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