Diseases of the Respiratory Organs. '171 



suflfocation, develops the usual symptoms. The causes 

 are exposure to cold draughts, severe cold weather, 

 particularly east winds, after the comforts of close and 

 warm quarters. 



The Symptoms consist of fever more or less severe in 

 proportion to the intensity of the congestion, which is 

 attended by a discharge, first of a watery nature, but later 

 becoming opaque, white and thick, as mucus and pus is 

 mixed with it, the attendant irritation causing the animal 

 to snuffle and snort, with attempts to eject the accumula- 

 tions. A watery discharge flows from the eyes, and this 

 also becomes purulent. Extension of these conditions 

 to the sinuses of the head produces heaviness with 

 dulness, with noisy respiration or "snuffling"; difficulty 

 of swallowing and breathing, with cough, may also arise 

 from the throat (pharynx and larynx) being involved, 

 when the fluids or food partaken of return by the 

 nostrils. 



Treatment. — In mild cases removal of the causes 

 usually suffices for cure. Advanced and severe forms 

 must be met by expectorant draught No. 3 or Bolus 

 No. I or 2. Support the strength by nutritious food of a 

 laxative nature. Frequent steaming of the nostrils is 

 highly useful. Avoid purgatives and emetics. The early 

 use of tonics is essential. 



Ozsena. — This term implies a chronic and often 

 offensive discharge from the nostrils, the result of con- 

 tinued or neglected nasal catarrh, and occasionally it is 

 caused by a polypus, portions of vomited aliment, or pus 

 from the lining membrane. {^See Polypus.) 



The Sig7is are a constant discharge of bad-smelling pus 

 from the nostrils, sometimes bloody, loud snuffling and 

 dulness of the spirits. The disease is also due to a 

 certain conformation, having contracted nasal chambers, 

 as seen in pugs and bulldogs. 



Treatment. — The nostrils must be kept clean, and the 

 passages frequently washed out by syringing with "Sanitas " 

 Fluid, solution of the chloride of zinc, or permanganate of 

 potash. 



Ozsena due to Parasites is somewhat common in
