I4 6 DISEASES OF THE DOMESTIC ANIMALS 



strophanthus, or camphor. Alcohol has been generally used for this 

 purpose, but most late researches seem to show that it is not a heart 

 stimulant but acts as a nervous sedative and may be of service as a 

 food in acute disease. 



When the mucous membranes present an icteric hue it is wise 

 to administer linseed oil (i pint) as a laxative and give sodium 

 bicarbonate (§ss) on the food, or in solution by the mouth, thrice 

 daily. If keratitis and iritis threaten, treatment must be pursued 

 as recommended under these disorders. 



Recently good results have been reported from the use of 

 polyvalent antistreptococcic serum as a prophylactic (ioc. c.) in 

 influenza. 



The patient should be isolated if possible and a beginning of 

 the disease may be suspected when an animal exposed to influenza 

 shows a rise of temperature. Communication of the disorder by 

 means of utensils, attendants, etc., should be avoided. Disinfection 

 of the premises should be practiced after recovery of the patient 

 (p. 282). 



Iritis. 



This occurs from trauma, in the course of acute rheumatism 

 and other infections, as distemper and influenza ; in periodic ophthal- 

 mia; as an extension of inflammation in ulcer of the cornea, and 

 in the sympathetic form when the other eye has suffered injury. 



Symptoms. — The chief signs and symptoms are pain in eye and 

 impaired vision ; inflammation of the conjunctiva about the cornea ; 

 pupils contracted and reacting sluggishly to light; change in color 

 (dull or rusty) of the iris; slight opacity of the cornea and pVipil; 

 and tension of the eyeball normal. Examine by throwing light into 

 the eye through a lens. The instillation of a one per cent, atropine 

 solution into the eye usually causes irregular dilatation of the pupil, 

 owing to adhesions at points to the lens capsule. In serous iritis, 

 minute grayish-yellow dots are seen on inner surface of the cornea.
