ULCKRATIVE STOMATITIS IN SOLIPEDS. 



Causes. Apart from the ulcerations and erosions of specific 

 diseases ( glanders, liorsepox,pu.->tulous stomatitis, aphthous fever, 

 etc.,) this condition is especially liable to appear in anaemic and 

 debilitated subjects (Cauvet), as in rachitis (Friedberger and 

 Frohner), cancer (Cadeac) chronic internal abscess (Cadeac), etc. 

 As an exciting cause and as a means of furnishing an infection 

 atritim for the microbes of ulceration all conditions of simple 

 lesion of the mucous membrane — mechanical, chemical, thermic, 

 venomous, etc., are operative. Dieckerhoff has described it in 

 connection with diphtheritic rhinitis, Friedberger with a nasal 

 and conjunctival catarrh, Zeilinger and Kohler with aphthous 

 fever, Mobius and Hackbarth with trefoil poisoning. 



Lesions and Symptoms. There is the usual dainty feeding and 

 disposition to masticate imperfectly or even to drop the partly in- 

 salivated morsels, working of the lips, the formation of froth on 

 their margins, and the drivelling of saliva in long strings or fila- 

 ments. As the disease advances this becomes bloody and foetid. 

 The local lesions may be at first like white pulpy spots of 

 softened and degenerating epithelium, which is exceptionally, 

 raised in blisters. This is followed by desquamation and the for- 

 mation of open sores which are indolent, and show a disposition 

 to further erosion and extension. They may be rounded 

 or irregularly indented in their borders, and contain a brownish, 

 blackish or greenish viscid debris. The}^ vary widely, however, 

 in general appearance and in their dispo.sition to speedy or slug- 

 gish healing, being apparenth' influenced by the nature of the 

 pathogenic microbe and the susceptibility of the subject. In 

 .some cases the molecular degeneration extends deeply into the 

 mucosa, and even over the edges of the lips into the adjacent 

 .skin. Recovery and complete cicatrization may take place in 

 one week, or successive outbreaks may take place in the same 

 animal lasting in all for months as in Cadeac's case associated 

 with chronic abscess of the mesentery. 



Treatment. The first consideration is to correct the debility 

 on which the affection is based. Iron and bitter tonics, mineral
