suffocation, 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.1 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. 
Ozena.—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 Ségns 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. 
Ozeena due to Parasites is somewhat common in
