Sometimes the irritabiUty of the part requires a 

 poultice previously to the use of the astringent, as 

 of goulard and bran. I have found scraped carrots or 

 turnips very useful for the purpose, after which the 

 astringent will act with better force. 



It becomes a question, whether in a case of con- 

 firmed grease, even if it were in our power, it would 

 be prudent to stop the discharge at once, for when se- 

 creting vessels have been long habituated to any ac- 

 tion they can seldom be suddenly checked with impu- 

 nity ; and in this case also, were the running stopped 

 without previous preparation for the change, it is more 

 than probable that some morbid effects would arise. 



To commence the cure, therefore, of confirmed 

 grease, we must prepare some other parts to take this 

 action of forming pus. But it is to be first remembered 

 that the discharge from grease is seldom a healthy one, 

 and it is hence much more difficult to check than one 

 that is simply purulent ; therefore while some other 

 parts are preparing to receive this purulent pus, the 

 heels themselves should be subjected to a treatment 

 that may produce a more healthy secretion in them. 



The best means I have ever witnessed for effecting 

 this, has been a fermenting poultice, made with either 

 parley meal, flour, oatmeal, linseed, or any other farina- 

 ceous macter capable of fermenting with yeast. This 

 should be applied every day as soon as mixed, and 

 suffered to perform all its fermentative process on the 

 leg : when, by the action of the carbonic acid gas, or 

 fixed air let loose, it is remarkable what a change is per- 

 formed on the part, bringing on, from the most ichorous
