muscles, and united by strong adhesions the left kidney with the 
two last ribs, the body and transverse processes of the lumbar 
vertebrae, the anterior border of the ilium and anterior crural 
muscles. Cut transversely and longitudinally, it was found to be 
formed of irregular cavities, separated by walls of variable thick¬ 
ness, and yellow in aspect. These cavities communicated, and 
contained a large quantity of grayish pus, in which floated hun¬ 
dreds of echinoccoci, some in their primitive spheroidal shape 
and containing a clear liquid, while others in greater number 
were shrunk and almost dry. 
Some of the cavities were distinct and closed. For instance, 
towards the anterior extremity of the tumor there existed one, 
subdivided also, and contained vesicles of various size. Some 
quite large contained a liquid in which floated smaller ones. 
Near the superior border of the ilium the tumor extended in the 
deep gluteal muscles, behind the hip joint, the posterior face of 
the femur and ended in cul de sac towards the inferior extremity 
of the posterior crural membrane. 
Again, towards the external angle of the ilium it was continued 
in the thickness of the triceps cruralis .—Archives Veterinaires. 
UPON THE SYNGAMUS TRACHEALIS AND ON THE DISEASE IT 
PRODUCES. 
By M. Megnin. 
There exists for several years back in France, and for a long 
time in England and America, amongst wild and domesticated 
gallinaceous, an epizooty which killed those animals by thousands. 
This disease is due to a parasite, a red worm which grows in the 
trachea and kills the birds by asphyxia. It is the syngamus 
trachealis of Siebold, well-known zoologically, but not so well as 
to as its anatomy and physiology, and unknown as to its de¬ 
velopment and mode of propagation.
