Treatment is like that for the ox, medicine being given in 

 about one-fifth of the doses. 



CROUP IN THE HORSE. 



The rare cases of croup in foals and young horses appear due 

 to the same general causes as in ruminants. M. Riss records two 

 cases, and Bonley one from breathing smoke when the straw of 

 the stable had taken fire. The suddeness of the attack, the spas- 

 modic symptoms and the duration of the disease and the treat- 

 ment do not differ materially from those given for the ox. 



PHARYNGEAL AND LARYNGEAL POLYPI. 



Pediculated tumors. Dyspnoea through change of position, operation by 

 ecraseur, snare, or cricoid incision. 



Tumors of varied structure developing in or beneath the muco- 

 sa of pharynx or larynx often become slowly detached until they 

 hang by a loose pedicle, and having much latitude of movement 

 they may at times slip between the arytenoid cartilages or even 

 into the glottis producing the most urgent or even fatal dyspnoea. 

 Pediculated tumors in the posterior nares lead to the same acci- 

 dent. In one case of multiple small tumors on the pharyngeal 

 mucosa of the horse, the largest and loosest, attached to the front 

 of the epiglottis, was occasionally displaced into the larynx 

 threatening instant asphyxia. One such attack supervened on 

 the opening of a suppurating guttural pouch by the writer, neces- 

 sitating prompt tracheotomy. A time was set for the removal of 

 the polypus, but the tracheotomy tube having been accidentally 

 displaced during the preceding night the patient died of suffoca- 

 tion. Dick mentions a polypus growing from the interior of the 

 larynx and causing loud roaring. Such tumors may be removed 

 by operating with the ecraseur through the mouth, or by a snare 

 passed through a long narrow tube and used to seize and twist 

 through the pedicle. If the polypus grows from the laryngeal 

 walls, it may be best reached by incision through the cricoid 

 cartilage and crico-thyroid membrane as in the operation for 

 roaring.
