DISEASES OF THE EYE AND SKIN. 229 



any others that may be weeping, as it is very infectious. The 

 inflammation caused by insects may be treated with the same 

 lotions as those advised above, and shade should be given as the 

 most important part of the treatment in all inflammations of the 

 eyes. 



DISEASES OF THE SKIN. 



These are of two kinds : those coming from within, as eruptions ; 

 and those induced by the presence of parasites or external injury. 

 The specific eruptions caused by sheep-pox we need not consider, 

 as they call for immediate notification. The sheep is ill before 

 the typical eruptions take place. They then pass through certain 

 recognised periods of papulation, vesication, pustulation, and 

 desquamation, by which they are distinguished from simple 

 eruptions. 



ECZEMA. 



Upon the uncovered portions of the skin, as under the thighs 

 and arms, eruptions appear as the result of indigestion, or foods 

 unsuitable in character. 



Symptoms. The animal appears dull, and moves with some 

 discomfort or soreness, which attracts attention. There may be 

 some elevation of temperature and indifference to food in the 

 formative period. The redness passes on to elevation of the surface 

 or pimply spots which presently contain a watery or milky fluid. 

 The movements of the animal are liable to break these pimples 

 or vesicles, and then a confluent sore is discovered. 



Treatment. A dose or two of salts, with a daily dram of bicar- 

 bonate of potash or soda, and the application of some lard (without 

 salt) or lanoline ointment any simple emollient will usually 

 suffice. The chief matter in treatment is the discovery of the 

 cause and its removal. 



DROPSICAL SKIN. 



Fluid swellings under the skin, as in rot, and other constitutional 

 conditions, call for treatment of the disease itself. They are but 

 local manifestations of a systemic condition, and not properly 

 diseases of the skin. 



SCAB OE SHAB. 



This is caused by a parasite of the mange class, and might be 

 described as sheep mange. 



Symptoms. Rubbing and coming out of the wool. 



Treatment. There is no great difficulty in destroying the para- 

 sites that give rise to scab, but there is often much trouble in
