ACUTE LARYXGITIS. 469 



culty in deglutition, with laryngeal irritation and cough, the 

 horse will gradually regain his former condition. In a few 

 others there is an evident tendency in the inflammatory action 

 to move downwards, and beginning with what is ordinarily 

 spoken of as a sore throat, may ultimately terminate in disease 

 of the minute air-tubes or of the pulmonary tissue. Occa- 

 sionally we find this pharyngo-laryngeal inflammation seems 

 to give way to, or is propagated into, that of particular inflam- 

 mation of the glands and gland-structures in the region of 

 the throat. These cases may terminate in apparently well- 

 developed instances of strangles, and the throat-symptoms 

 may subside as soon as those of the glands are developed, or 

 they may continue while these exist, and only defervesce with 

 the maturation of the glandular inflammation in a well- 

 developed abscess. 



In the form of cedematous lar3rngitis — oedema glottidis — 

 the severer cases give no time for much or extensive textural 

 alteration. For when the laryngeal symptoms are not speedily 

 ameliorated, the probabilities of a rapidly fatal termination 

 from interference with the function of respiration are very 

 great. 



In other manifestations, especially such as accompany 

 certain specific fevers, or appear as sequels of these, this 

 cedematous larjrngitis assumes a subacute or chronic form, and 

 as such may remain for a rather lengthened period, only 

 troublesome or even attractive when the horse is moved 

 rapidly, or when engaged in feeding. 



Treatment. — Besides strict attention to location, i.e., the 

 placing of the suffering so that the influence of cold air or 

 draughts may be avoided as much as possible, with an equable 

 rather warm and moist atmosphere, the only general treatment 

 which we have observed to be productive of much or any benefit 

 is that by which excessive febrile action is mitigated, and the 

 animal steadily supported and guided until the fever has run 

 its natural course. From the irritable condition of the throat 

 and contiguous parts, it is nearly impossible to administer 

 medicine either in the solid or liquid form. If the abihty to 

 swallow is not entirely gone, the ordinary febrifuge powders of 

 chlorate and nitrate of potash may be given twice daily in the 

 drinking-water, or probably the form of electuary may be cm-
