GENERAL SYMPTOMS OF DISEASE. 333 



condition in which the artery resists compression; it results from 

 contraction of the muscular coat of the arterial walls. Hardness 

 of the pulse is often associated with smallness. It is then termed 

 corded, wiry, or thready. This pulse is seen in the early stages 

 of inflammatory diseases. 



SYMPTOMS CONNECTED WITH THE RESPIRATORY 

 FUNCTIONS. 



The respiratory movements may be quickened, difficult, 

 labored, wheezing, roaring, steriorous, spasmodic, convulsive, 

 irregular, slow, thoracic, or abdominal. 



Quickened breathing may be produced by any cause which 

 accelerates the circulation of the blood, as exercise. 



Difficulty of respiration is a prominent symptom of disease, 

 and is associated with all respiratory diseases, as inflammation of 

 the lungs, pleura, larynx, and trachea. 



Stertorous Breathing — Snoring. — This breathing is a 

 symptom of brain disease. When the inspirations are delayed 

 and then performed with a sudden noise and jerking effort, with 

 diminished susceptibility to outward impressions, it is a symptom 

 of the approach of death. 



Abdominal breathing is performed by the animal holding the 

 ribs in a fixed position, owing to pain in the chest. It is a symp- 

 tom of pleurisy and other chest troubles. 



Thoracic breathing is where the abdominal muscles are pre- 

 vented from taking part in the respiratory movements, an account 

 of abdominal pain or obstruction. 



Irregular breathing is where there is a want of harmony in the 

 expiratory and inspiratory movements, as in broken wind. 



COUGH. 



This renders some aid in diagnosis. Coughs are known as dry, 

 moist, short, hacking, violent, spasmodic, those peculiar to broken 

 wind, and roarers. 



The moist cough attends catarrh, bronchitis, and diseases
