102 THE VETERINARY DOCTOR. 
TREATMENT.—Aconite may be used for all coughs with inflammation, 
either of the mucous membrane lining the air-passages or of the sub- 
stance of the lungs. In inflammation of the membrane of the air-passages the 
membrane is dry. When the lung-substance is affected, the pulse is strong 
and quickened, and the breathing murmur diminished, with a sawing kind 
of sound, called bronchial respiration. In such cases the cough is dry, 
short and frequent. As soon as secretion returns to the mucous membrane, 
or the pulse becomes small and feeble, aconite should be left off, or alter- 
nated with some remedy adapted to the nature and location of the disease 
on which the cough depends, and of which it isa symptom. Give bella- 
donna when the cough is short, dry and barking; worse in the evening or 
night, seemingly caused by trouble in the throat; when there is sore throat 
with difficult swallowing, or chronic cough. Administer arsenicum for dry 
cough, in the evening or at night, after eating or drinking, or going up hill, 
or from contact with cold air; difficult breathing; thin discharge from the 
nostrils; for coughs following catarrh of a weak type and influenza. When 
the cough is dry, hoarse and spasmodic, worse in the morning, after exercise or 
after eating, and attended with disorder of the stomach, furred tongue, foul 
mouth, uncertain appetite, and constipation, give nux vomica. Phosphorus 
is needed for a dry cough excited by cold air, drinking, irritation and tickling 
in the windpipe, and attended with discharges of phlegm and difficult 
breathing. Give bryonia for a cough which requires much effort, and 
cuts short the breathing; cough during frosty weather, or east winds, 
or after eating and drinking; continued dry cough, especially in the 
morning, attended with rattling in some part of the windpipe, caused 
by tenacious mucus cr soft lymph, and produced by pressure on the 
pait of the windpipe where the rattling occurs. Iodine is indicated 
by cough situated in the larnyx or windpipe, accompanied by soft 
secretions, or dependent on chronic inflammation of the mucous mem- 
brane, with foul discharge from the nostrils; the same remedy is use- 
ful for irritable but not inflamed salivary glands. Tartar emetic is ser- 
viceable for bronchial cough, when it is loose and attended with an 
abundant discharge of mucus, loud rattliug, and painful breathing. Give 
cannabis for frequent attacks of fitful, hollow-sounding cough, occurring 
only in the morning, or for coughs in the evening, and not extending 
through the night. Kali bichromicum is effectual for tough, ropy, sticky 
phlegm of long-standing cases, and when the tongue is covered with fur. 
Spongia is demanded for shrill, sharp, ringing cough; inflamed windpipe; 
or dry, hollow, barking cough; loose cough; suffocating cough; violent 
racking cough; rattling in the bronchial tubes. For coughs of the various 
respiratory difficulties refer to those ailments.
