CHAPTER XIII. 



STRONGYLUS BRONCHIALIS. 



General and specific characters of Strongylus bronchialis and Eustrongylus gi(/as — Organi- 

 zation of the latter — Characters of Sclerostoma duodenale and Oxyuris vermicularis — 

 Conflicting statements respecting the anatomical peculiarities of the Oxyurides — 

 Opinions of Eberth, Ktichenmeister, Walter, Schneider, Davaine, Claperede, and 

 others — Development — Injurious effects on man- — Treatment. 



Although we are at present but very imperfectly acquainted with 

 the phenomena connected with the hfe-history of the human nema- 

 tode species which still remain to be described in this work, yet, 

 from the data furnished by the habits of the larvae of Trichinse, 

 there can be little doubt that we are now on the eve of fresh dis- 

 coveries ; and, it may be added, this desirable result is likely soon 

 to show itself, because both in this country and abroad, a small but 

 vigorous band of helminthological workers are busily engaged in 

 experimental inquiries. Without further prelude, I hasten to 

 consider these remaining parasites : —
