feet. Its first appearance is in the form of a hard prominent 

 tumonr, characterised by its heat and much tenderness on pressure. 

 As it matures, the hair gradually drops off, leaving the affected part 

 a bare dry spot. The treatment for quittor would of course vary in 

 many cases : but, as a rule, let the foot be well pared out, and the 

 wounds cleaned ; then let a bar-shoe be fitted out so that no pressure 

 is applied to the affected parts ; then by the use of astringent or 

 caustic agents, as the case may be, attempt to set up healthy action. 

 If there be much inflammation a poultice may be used, or the 

 wound may be dressed with some preparation of opium. Some have 

 recommended arsenic, others verdigris, and others blue vitriol. 



A well-known author thus writes as to the best treatment : " A 

 quantity of caustic is introduced into the sinuses, and dead matter is 

 subsequently sloughed out in the form of a 'core,' and if the case 

 goes on favourably, healthy structure is formed in its place ; if not, 

 a repetition of the treatment is called for. Corrosive sublimate is 

 one of the most powerful remedies, and is used in the form of 

 powder, which is rolled up in paper and passed into the sinuses, or 

 mixed with an equal weight of flour and made into a paste with 

 water, the mass being moulded into small rods of a convenient size, 

 which, when dr}^, are thiTist into the sinuses in the same manner as 

 the paper tubes. Sulphate of zinc is a very good caustic, and may 

 be either introduced into the canal in small pieces, or in powder, or 

 injected in the fonn of a strong solution. Chloride of zinc (disin- 

 fecting fluid) is also frequently injected, either in its undiluted state 

 or mixed with various proportions of water. After the caustic dress- 

 ing has been applied, a poultice should be tied over the whole of 

 the foot to alleviate the pain and inflammation which will certainly 

 follow. In the course of a few days the slough, or ' core, ' will 

 propably come away in the midst of a poultice ; and if the wound 

 should then assume a healthy character, very little beyond mild 

 dressings, such as poultices or warm water applications will be 

 necessary. But should the dense texture of the sinuses be again 

 formed, a repetition of the caustic will be necessary, and it may be 

 desirable to use stronger remedies ; the hot iron is in favour with 

 some practitioners."
