It has long been an established practice 

 after drawing a corn, an injury sustained in 

 any part of the hoof, causing a partial defect 

 or a diseased state of the frog, as inveterate 

 thrush, &c. to protect the part with a bar-shoe, 

 formed and adapted to such purpose ; this is 

 certainly a conditional security ; but there is 

 still a space between the foot and the shoe to 

 receive and retainany substance that may be- 

 come injurious by its lodgment and painful 

 pressure as before-mentioned. To prevent 

 the possibility of w4iich I should always re- 

 commend (incases that require it) the insinu- 

 ation of a sufficient quantity of tow to fill up 

 the interstice ; and that its retention there 

 nii":ht be rendered a matter of sweater cer- 

 tainty, it should be well impregnated with a 

 portion of diachylon ivith the giuiis, first 

 melted over the fire ; this will not only fill up 

 the opening with neatness [properly 7nanaged) 

 but form a bolster ofeas.e to the part, and ex- 

 clude to a certainty the admissio^i of articles
