a severe attack of colic, if not promptly treated; yet it is a diffi- 

 culty easily managed, if it is known what to do, and it is done 

 promptly. An attack of pneumonia is a very serious thing; but 

 during its first 

 stages is easily 

 managed if taken 

 in hand at once. 

 A horse that is 

 foundered, if not 

 treated promptly, 

 is practically ruin- 

 ed, as a change of 

 structure quickly 

 i-esults; yet every 

 case of acute foun- 

 der or laminitis is 

 curable, and not 

 only this, but the 

 treatment is so simple that it is not at all difficult to comprehend 

 or apply. Navicular-joint lameness is sure to ruin a horse if not 

 taken immediately in hand ; yet it is one of the simplest of diffi- 

 culties to manage in its first or acute 

 stages, and hence the knowledge of its 

 treatment is of the greatest importance to 

 owners. Shoeing: A horse badly or im- 

 properly shod, no matter how good the 

 feet, if the hoofs are thin, is liable to be 

 soon practically ruined. 



The treatment for these difficulties will 

 be found to be particularly careful and 

 thorough. There are, of course, many other 

 difficulties which it is important to know 

 how to manage, for which the best practical 

 treatment is given. In fact, the medical 

 department of this work will be found en- 

 titled to the fullest confidence, and must be accepted as invaluable 

 to horse owners. The writer would, however, recommend that 

 m all critical cases the safest course is to employ a competent vet- 

 erinary surgeon, if available.
