66 DISEASES OF THE DOMESTIC ANIMALS 



indicated. Colds are due directly to infection and chiefly to cocci 

 contained in dust. The avoidance of dust by care of roads and 

 isolation of animals with coryza are thus desirable. 



During an attack the animal should have an abundance of cool, 

 pure air indoors, or, better, outdoors in suitable weather. The 

 covering should be moderate, but the legs may well be rubbed with 

 mustard water paste, and bandaged, if the animal is in the stable. 

 The food should be laxative, with roots, bran mashes and a few 

 ounces of linseed oil. If medical treatment seems desirable, the 

 dropping of fluidextract of belladonna on the tongue (H., 5ss every 

 two hours for the first few days) may arrest the coryza, and this 

 may be aided by inhalation of steam twice daily (co. tine, of benzoin, 

 i tablespoonful to i gallon of boiling water). Local treatment is 

 best but difficult to secure in veterinary medicine. Thus, following 

 the human treatment by spraying every two or three hours adrenalin 

 chloride in 1-10,000 dilution into the nasal chambers will be most 

 effective (together with belladonna) in cutting short the coryza. 



In ordinary mild cases drug treatment is unnecessary. When 

 fever exists the animal should be kept quiet in the stable. The 

 severer forms of coryza caused by special infections should receive 

 much the same treatment : as the rhinitis in which vesicles, pustules 

 and scabs are seen; the croupous form; and that in which yellow 

 nodules and ulcers occur on the septum and on the skin about the 

 nostrils and nose, with enlargement of the lymph nodes under the 

 jaw and in the neck. Isolation is here especially important. 



Cystitis, Acute and Chronic. 



The causes of cystitis are, first, congestion; and second, in- 

 fection. Congestion arises from over-distension of the bladder, 

 external chills, trauma, sexual excesses, abnormal urine containing 

 irritants, calculi, tumors, passage of instruments — these are pre- 

 disposing causes. The immediate cause is infection from germs 

 eliminated by the kidneys in general infections, those carried to the
