 stitution more derangement than the cutting of all

 ease, pulmonary in particular, setting in at this inter- 

 val is doubly dangerous, from its being augmented 

 or kept up by the existing irritation of teething; in 

 fact, teething is one auxiliary cause of the known 

 fatality among horses at this period of their lifetime." 



The effects of permanent dentition upon the con- 

 stitution of the animal are many, and often of a 

 severe character. In fact so much so that the animal 

 will become very much depleted and will be unable 

 to withstand many of the surrounding conditions 

 which are productive of disease. Among such dis- 

 eases may be noted catarrhal disorders, cough, swell-
