One case of niglit bliudness ; and as previously mentioned, 

 134 cases of periodic optlialmia bave also been reported. 



Reports of four outbreaks of head scab among sbeep have 

 been received. This is a disease of the skin, and is caused 

 by a mite (sarcoptes scabiei, var. ovis) which attacks the skin 

 of the short wool regions of the head and legs. In attack- 

 ing the skin of the eyelids, it produces entropium which 

 leads to inflammation of the conjunctiva and cornea. Scrape 

 the crusts from the affected places and apply any good sheep 

 dip, once every eight days for one month. 



The writer has also observed a few cases of diphtheritic 

 conjunctivitis among turkeys and chickens. Separate the 

 sick ones from the healthy and wash the eyes and the dis-

 of corrosive sublimate (1 to 500).

 has occurred, in nearly every instance, as a result of feeding- 

 rotten or mouldy corn. Curative treatment is usually ineffec-

 of the bones, manifest by enlargement of the facial bones, 

 of the lower jaw bone and the bones of the limbs, and nearly 

 always leading to the "breaking down" of the horse after a 

 long period of more or less severe rheumatic lameness. 

 This disease is generally fatal. Excellent care with the va- 

 riety in diet, as suggested to prevent moonblindness, will be 

 good preventative, as well as palliative, treatment in this 

 disease. 



A few cases of malignant catarrh ("hollow horn?") have 

 been reported and also a few cases of Parturient Apoplexy 

 ("milk fever") among^ cattle. 



Hog cholera raged in several counties last year, and has 

 appeared in some counties this year. The disease has done 

 the most damage in beats and counties where hogs bave
