great importance. Not infrequently a diagnostic conclusion 

 in a clinical case is reached largely through the impression 

 the patient makes upon us by its habitus. 



Obvious physiological abnormalities are sometimes of 

 themselves an index to the character of the disease. How- 

 ever, one should guard against reaching hasty conclusions 

 from the first impressions of the patient, to the neglect of a 

 thorough examination. 



_, 1. Attitude of tlie patient. Healthy horses as a 'rule 

 remain standing during the day, or if lying down they imme 

 diately rise to their -feet at the approach of a stranger. The 1 

 will frequently lie flat on the side with feet extended, pro

Healthy cattle lie down often during the day, especially 

 just after feeding, and they are not so prone to rise when 

 approached. They seldom lie flat on the side, but in sternal 

 decubitus the limbs folded under them. 



Healthy sheep jump up when approached and usually 

 run away. 



The attitude of sick arrmals whether standing, walking 

 or lying down is often of value in diagnosis. 



Standing attitudes assumed during disease. The head 

 is held stiffly and extended in pharyngitis, cerebro-spinal men- 

 ingitis, muscular rheumatism, malignant head catarrh of the 

 ox, and in acute encephalitis of sheep and goats. 



Very sick animals usually hold the head dozen, and as- 

 sume a relaxed languid attitude, the ears drooping; horses 

 rest their feet alternately. 



Cows suffering from severe vaginitis stand with arched 

 back, tail held high, and legs spread apart. They do not
