392 THE IMPROVE ED ..RT OF FARRIERY. 



for the foot rot. We have given three recipes or for- 

 mulse ; the first, or milder preparation, will answer 

 the purpose in slight incipient cases ; but in those 

 of long standing, the stronger caustic will be found 

 necessary. 



1. (mild.) 



Sulphate of Copper - - 2 ounces. 



Water - - - - - 12 ounces. 



Sulphuric Acid - - - 2 drachms, 



2. (stronger.) 

 Powdered Verdigris - - 1 ounce. 

 Nitrous Acid - - - 2 ounces. 

 Water _ _ . 4 ounces. 



3. (strongest.) 



Red Nitrated Quicksilver - 1 ounce 



Nitrous Acid - - - - 2 ounces. 

 Spirits of Wine - - - 3 ounces. 



Dissolve the nitrated quicksilver in the acid, and 

 when perfectly dissolved add gradually the spirits 

 of wine. 



It may be necessary to dilute this sometimes with a 

 little water ; and it should be remarked, that after 

 applying either of these preparations once or twice, 

 the sore part will generally have a more healthy ap- 

 pearance, and then some mild application will be most 

 proper, such as Friar's balsam, or tincture of myrrh. 

 It is likely that a mixture of tar and turpentine would 

 prove a useful application in such cases, as it may tend 

 in some measure to protect the diseased part from 

 moisture. For some time after the feet have been 

 dressed, the sheep should be^kept ina dry place ; turn- 

 ing them in a limed fallow has been strongly recom- 

 mended. 



The following judicious treatment of this disorder 

 is recommended by Sir George Mackenzie : —
