of a dependent opening made by which the accnmulated pus mav escape^ 

 and this opening mav be enlarged by farther paring awav the hoof, so as 

 to reach the softer part, that can be more readily cut with a keen knife. 



A small probe, or bougie, should be inserted from above, and worked 

 to the lowest depth of the sinus. If this extends far towards the base of 

 the foot, the prime object should be to get an opening from below to 

 meet it, no matter what may have been the cause — whether x prick, x 

 bruise, or irritation caused by other foot diseases. This dqpendeBt <^>eii- 

 ing established and kept open, the pus will in tim'e be eracaated, and the 

 foot will return to its healthy state, unless the joints have heen. attacked, 

 in which case a cure is scarcely to be hoped for. 



If the disease is of long standing, the internal surface of the sinus or 

 sinuses has become more or less callous, and a stimulatii^ lotion must be 

 injected with a syringe every day. composed of one draclim chloride of 

 zinc to one pint of water — increasing the chloride gradoallv to two 

 drachms. 



This treatment will suffice. The main trouble, however, is to make the 

 dependent outlet. In case this c-annot be done, owing to the shallowness 

 of the sinuses from above, reduce the inflammation by poulticinc:, as pre- 

 viously directed, ^nd then inject this somewhat caustic solution into each 

 channel or pipe :

Do this three times the first day. twice the seocMad day, and once a dav

K it is found impracticable to inject this solution into the openings, 

 adopt this instead: Insert, by means of a wet probe, a mixture of 

 corrosive sublimate and flour (three p»arts of flour to one of corrosive 

 sublimate ) . Persevere until you know that every part of the sinuses has 

 felt the caustic. In two or three days thereafter they will b^:ia to dis- 

 charge a white, curd-like matter. It may be necessary to repeat this, 

 but if thoroughly done, and there is no affection of the joints, a cure may 

 be expected. 



Sometimes the trouble rises from a gravel having insinuated itself 

 between the shoe and the sole, and creating a bruise or com. This may 

 be ascertained by removing the shoe and seeking for a spot unnatural in 

 appearance, hot, and tender on the sole. If found, it ought to be pared 

 down so as to reach the more sensitive part of the foot, and, if possible.
