the inflammation has continued for some time the secretion 

 from the lining membrane of the part is arrested (this is 

 called the dry stage) ; then comes an increase of secretion. 

 As the inflammation continues there is a superabundance of 

 perverted mucus; this is in appearance like ropy saliva 

 hanging from the mouth. In addition to these symptoms 

 the head and neck are held straight out, to favor respiration 

 and relieve in some measure the distress of the patient. The 

 febrile symptoms are more or less severe in proportion to

 of the horse. Much the same pernicious influences men-

 produce bronchitis. Besides these, during the spring and 

 fall of some seasons, this disorder seems to be epidemic,
