danger of severe corneal involvement. The inflammation lasts 

 about two weeks and cold applications should be made frequently 

 to the eyes during this time. 



Follicular conjunctivitis may occur as distinct from the granu- 

 lar form, as shown by the absence of pannus, thickening of the lids 

 and entropion in the former. Enlarged follicles appear on the 

 conjunctival surface of the lids with slight mucous discharge. The 

 treatment is the same as for the acute catarrhal form. 



Phlyctenular conjunctivitis is characterized by yellowish-red 

 elevations, or phlyctenules, about the margin of the cornea or on 

 the cornea, sometimes as large as a split pea, and surrounded by a 

 zone of congestion. The phlyctenule tends to ulcerate and is 

 attended with photophobia and lachrimation. If on the cornea, a 

 keratitis with opacity may result. The disease is not contagious. 

 One eye only is often affected. A solution of boric acid (3 per cent. ) 

 should be dropped in the eye three times daily and, with corneal in- 

 vasion and photophobia, atropine also (gr. i-iv to §i). Once 

 daily ointment of yellow oxide of mercury ( 1 per cent. ) should 

 be inserted between the upper and lower lid, in amount as great 

 as a split pea. Attention to the general health is important ; a tonic 

 powder containing nux vomica, copperas and quinine may be given 

 the horse. The bowels should be kept open. 



Constipation in Dogs. 



Constipation in dogs is caused by a diet containing too great a 

 quantity of soft food, as much bread or porridge ; or too dry food, 

 as bones. Insufficient exercise, old age and various diseases pre-

 inflamed and swollen anus, are often observed. A tender, fecal 

 tumor may be felt in the belly and accumulation of dried feces by 

 the finger in the rectum.
