192 DISEASES OF POULTRY. 



bleeding. After the crusts are removed dress the af - 

 fected part once a day with any one of the following 

 preparations : Tincture of iodine. Benzine 1 part, 

 soft soap 20 parts; mix thoroughly before using. Or 

 carbolic acid 1 part, soft soap 20 parts, to be well 

 mixed. The carbolic preparation should not be ap- 

 plied to a large surface at one time as the acid may be 

 absorbed and cause poisoning. A good ointment may 

 be made with either calomel or red oxide of mercury 

 1 part to 8 parts of vaseline. If the above mentioned 

 remedies fail a more active, but also more dangerous 

 ointment may be made by mixing 3 grains of nitrate 

 of silver with % ounce of vaseline. This ointment 

 should be made by the druggist and carefully rubbed 

 upon the diseased surface. Another remedy, which 

 on account of its poisonous character should only be 

 used as a last resort, is made by dissolving 10 grains 

 of corrosive sublimate in an ounce of water. 



In the remedies here mentioned the means are pro - 

 vided for effectually arresting this troublesome malady 

 and eradicating it from the poultry -yard. If taken 

 in time, the application of the milder preparations 

 daily for a few days will be sufl&cient ; but in case a 

 number of birds become affected and particularly if 

 feathered parts are involved, the more active agents 

 will be required. It is, also, necessary to adopt sani- 

 tary regulations. The affected birds should be sepa - 

 rated from the well ones, and the houses and ruis 

 should be disinfected with limewash and carbolic 

 acid solution.
