134 THE SUMMERING OF HUNTERS. 



want of the little pliysiolo,2;ical knowledge we have 

 here attempted to conve}' ; and. secondly, we could 

 not have finished onr subject satisfactorih% because 

 our readers could not have been introduced to the 

 rationale of exercising, blistering, firing, setoning, 

 mercurializing, &c., without this knowledge. 



In concluding what we have now to say about 

 the use of mercury as an external application for 

 disease of the lubricating apparatus, we again say 

 that when a mild preparation is required, the oleate 

 will be found to answer every purpose, and more 

 efficiently than the common mercurial ointment. 



The subject of firing we shall pass over just now, 

 because it is almost indispensable to employ skilled 

 assistance. 



Blistering we shall say a few words about, because 

 practical horsemen so frequently blister their horses 

 without advice. What we have to say will not be 

 exhaustive. A few hints will not come amiss here. 

 First, as to the kind of blister. It was thought 

 long ago that the Spanish blistering fly or can- 

 tharides was the best, if not the only reliable and 

 good blister. For some years the biniodide of 

 mercury has been largely used. This is little if at 

 all inferior to the fly blister for any purpose, and 

 in diseases such as windgall, thorough-pin, &c., 

 some actually prefer the biniodide. We prefer it 

 in these cases to the fly blister. It is soon made 

 by adding one drachm of the biniodide of mercury 

 to one ounce of common lard, which has had its
