Notions of what the Farriers term Hoof-founder, 



when I come to treat of the Difeafes of the Hoof.^ W?nd"nd 



Broken Wind and Purji-venefs in Horfes is what in p^^rf^ pre- 

 human Creatures we call Afihmatick and Phthijicky. nefs. 



The Caufe of Purfivenefs and broken Wind pro- The 

 ceeds from Surfeiting, hard Exercife upon a fuU^^"^^- 

 Belly, Riding a Horfe into Water when he is hot 

 and fweats ; andlaflly from obfiinate Colds ill cured. 



I need not be tedious in enumerating the Signs or The Signs. 

 Symptoms of Purfwenefs, and broken Wind, by

 Colds, he will eafily know the Difference. Befides, 

 the Cough does not found fo deep in Purfivenefs, 

 but on the contrary is a fhort tickling one, as if it
