DISEASES OF THE HOa 93 



servers think the young worms force their way di- 

 rectly through the intestine and all the interven- 

 ing organs, until they reach a suitable habitation 

 in tlie voluntary muscles. According to Dr. Leuck- 

 art they travel by way of the inter-muscular con- 

 nective tissue, and are found most abundantly in 

 the groups of muscles nearest the abdominal cav- 

 ity-, especially in those that are smallest and have 

 the most connective tissue. The cysts containing 

 trichinae were first observed in human muscles in 

 1882, but the worms were first named and described 

 by Owen in 1835, but were only regarded as anatom- 

 ical curiosities of no practical importance, until 

 1860, when Zenker proved that they are capable of 

 producing the severe and often fatal disease now 

 well known under the name of Trichiniasis, but 

 which has been previously confounded with ty- 

 phoid fever, inflammatory rheumatism or rheu- 

 matic fever, poisoning and other diseases.
