A CALK UPON THE INSTEP 



I have found the most troublesome to treat, from the circum- 

 stance that the tendon of the extensor pedis passes over that 

 part and is often lacerated just where it is inserted into the 

 superior process of the os pedis. In such cases the bone fre- 

 quently gets involved with the tendon, Caries supervenes, and 

 separation of the tendon from the bone would necessarily fol- 

 low. Such cases may then be considered incurable. When 

 they occur near the quarters they are less dangerous, but they 

 sometimes take on the 



CHARACTERISTICS OF QUITTOR. 



The suppurative matter that forms in these tissues is of a 

 very acrid nature, and it eats its way, when it has no way of 

 escape, forming burrows or sinuses in various directions, not un- 

 frequently causing a detachment of the hoof from its connec- 

 tions with the sensitive tissues. 



A REMARKAELE RESEMBLANCE. 



I have known a mere tread, giving no external evidence of 

 injury to the feet beyond the gait and manner of moving its 

 leg, almost peculiar to an injury in this particular spot. I say 

 almost, because the movement very closely resembles that of a 

 horse with Stringhalt. It is raised from the ground much 

 higher than usual, and is placed upon it again with as little 

 flexion of the foot as possible. Such cases as these are com- 

 monly neglected until too late to effect a cure. The intention, 

 in all cases of this nature, should be to prevent or arrest sup- 

 puration. 



The chances of safety for the animal depend upon the ful- 

 fillment of this condition. The most powerful antiseptics are 

 indicated in the advanced stages. The less powerful may be 

 sufficient in the earlier stages.
