DISEASES OF THE HOG. 98 
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 the 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 thewormswere first named and described 
by Owen in 1835, but were only regardedas anatom- 
ical curiosities of no practical importance, until 
1860, when Zeuker 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.
