tain, staggering gait, and may fall and make convulsive but in- 

 effectual efforts to rise. Dyspnoea, blue mucosae, and protruded 

 tongue, are noticeable in such cases. In the slighter cases, dull- 

 ness, inappetence, suspended rumination, drooping head, and 

 trembling limbs are characteristic features, and profuse lachry- 

 mation is constant, In some eyes there is a small opaque spot 

 around a minute ulcer containing small granules like dust or 

 sand, and situated in the centre of the cornea on the line of ap- 

 proximation of the two eyelids. Larger opaque areas when 

 present were generally confined to the corneal surface, without 

 any areola of distended vessels, and without a vascular zone at 

 the junction of cornea and sclera. In certain cases the whole 

 transparent cornea stood out in the form of a vesicle, so promi- 

 nently as to interfere with closure of the eyelids. The affection 

 might attack both eyes or only one. 



An important feature is that cattle coming from the cars in 

 this condition and left at rest for five days on hay without cotton 

 seed recovered rumination and appetite, and the weakness and 

 nervous excitement or depression disappeared. There remained 

 only the lesions of the eye which progress tardily according to 

 their extent or severity. 



The southern origin of the cattle, together with the congested 

 liver and spleen and the high colored urine would have suggested 

 the southern cattle fever, but from the promptitude of the re- 

 'covery under a change of regimen and the prominence of the 

 lesions of the eye. 



The important point in connection with this subject is the 

 prophylaxis by avoidance of the too liberal diet of cotton seed. 

 "When the disease has actually set in, the true course is to suspend 

 this aliment, clear the bowels of any that may remain therein, 

 and treat the lesions of the eyes according to their respective con- 

 ditions.
