II. Complications .—We have already seen that quarter cracks 
and dry corns are common affections of contracted feet. Exos 
tosis of the phalangeal region is also commonly met in such feet, 
especially side-bones. Knuckling, and diseases of the tendons 
and of their sheaths are also often caused by contractions of the 
cet. "1 lie icst of the foot on its whole surface is thus perverted 
and the tendons become retracted, painful and swollen. 
Navicular disease is so often met with in company with con- 
tracted feet, that one disease is frequently'mistaken for the 
other. 
Laimnitis has been said to he also one of the complications; 
if so, it is at least, quite rare in its occurrence. 
Tetanus has sometimes been observed among its associations, 
and Hartman attributes the development of so-called idiopathic 
cases of that disease, to this condition of the feet. 
The emaciation of the affected leg is a complication seen 
also, with other forms of lameness.

It is a curious fact, and one which requires further study and 
explanation, tnat while the Taenia Saginata is the common tape 
worm of this country, its larvae, the measles of beef, are very 
seldom met with. On the other hand, while T. Solium is by 
no means so prevalent, yet its larvae, the measles of pork, are 
not at all infrequent. Cobbold* refers to this, and states that 
not a sil igle instance has been recorded of the occurrence of 
these cystic parasites in the United Kingdom, except in our 
experimental animals. Of course much more fresh beef and
