hastened by irrigation of the nose with a 1 or 2% sokition 

 of carbonate of sodinm. Since the disease is often contagious, it 

 is advisable to isolate the sick animals. 



Necrosis of the Nasal Mucosa. It occurs very rarely as a primary 

 disease after traumatic, chemical, thermal iusults or after au iufection 

 (bacillus necrophorus) ; as a rule there are other underlying primary 

 affections (morbus maeulosus, acute glanders, also strangles, malignant 

 catarrhal fever) which have first occurred. After the shedding of the 

 necrotic portions of mucosa, deeply penetrating, dark red, or grayish-red, 

 uneven ulcers are formed, with more or less elevated margins, around 

 which the mucosa is inflamed. The submaxillary lymph glands are in 

 a condition of acute swelling. The affection can usually be differentiated 

 from glanders by the absence of glanders' nodules; sometimes, however, 

 a differential diagnosis can only be made after a thorough bacteriological 

 examination, as was shown in a case of Rabe. 



7. Follicular Inflammation of the Nasal Mucosa. 

 Rhinitis follicularis. 



(Rhinitis piisfulosa; Coryza pustulosa equoruui [Kitt].) 



Follicular rhinitis is a peculiar inflammation of the nasal 

 mucosa with nodule formation of the mucous glands, which nod- 

 ules break down later on. The sebaceous glands of the skin of 

 the region of the nose become similarly affected. 



Occurrence. This is a disease of solipeds which occurs 

 enzootically under conditions similar to those which are ob- 

 served in croupous inflammation of the nasal mucosa. 



Etiology. The disease undoubtedly owes its origin to an 

 infection, as shown by the observations of its contagious nature 

 by Roell and later by Friedberger & Frohner. Kitt believes 

 that streptococcus equi is the causative factor; Friedberger & 

 Frohner likewise believe that this is probable. 



Symptoms. The disease begins with the s^anptoms of a 

 violent nasal catarrh and as a rule with fever, whereupon, after 

 two or three days, nodules, of the size of a millet seed, develop 

 on the intensely reddened mucosa of the nasal septum. These 

 nodules are quite numerous and they can be felt easily with 

 the palpating linger. The nodules increase in size, become 

 yellowish and frequently confluent and form a continuous yel- 

 lowish surface; this disintegrates, becomes pale yellow and 

 leaves after its removal small, roundish, shallow, intensely red- 

 dened ulcers with slightly infiltrated margins. The ulcers heal 

 completely within a few days. In most cases similar nodules 

 are developed on the skin of the alse of the nose, the upper lips 

 and the cheeks. These nodules also become yellow, ulcerate and
