126 DISEASES OF SHEEP. 



Is the mouth dry or moist, hot or cold, and is it covered 

 •with froth? Does the animal perspire easily? Does it 

 urinate frequently or seldom, much or littla? Does it re- 

 quire exertion, and is it painful? Does the urine come 

 gradually and in drops ? Is it thick or thin, watery, clear, 

 troubled or bloody? 



With regard to the senses. Is the animal sensitive to ex- 

 ternal impressions or dull? Are the eyes opened or closed, 

 clear or dim, shining or dull, and is the animal insensible 

 and stupid ? 



With regard to the organs of loeonwtion. Does the animal 

 stand with curved back ? Does it look at its belly in a 

 restless manner, or is it quiet ? Does it lie down and roll 

 about ? Are its motions lively or slow and lazy ? Does it 

 limp and totter ? Is the neck movable or immovable, hard 

 or stiff? 



It must be further considered if one or more parts suffer 

 at the same time. 



Even if owners of cattle cannot recognize the disease 

 from the group of symptoms, they will be able to give the 

 veterinary practitioner valuable information concerning the 

 commencement of the disease, and enable him to fix on a 

 plan of treatment much sooner than without such informa- 

 tion. 



Another way of recognizing diseases is to dissect animals 

 after death, and examine the different organs as to their 

 texture, color, consistency, position, changes, etc. Such 

 post-mortem examinations mostly enable one to determine 

 the character of the disease with certainty if this could not 

 be done during life, and to ascertain its seat and the reason 

 of its fatal termination. It is necessary, however, in cases of 

 errors, doubts and wrong conclusions, to consult practical 

 veterinarians, possessing thorough anatomical knowledge, 

 and not quacks who are destitute of it, as is too often the case.
