quoted above recommends in severe cases an oint- 

 ment of the following composition and proportions : 



Corrosive sublimate . 

 White hellebore, in powder 

 Whale or other oil 



Hosin 



Tallow . . . . 



8 02. 



12 oz. 

 6 gallons. 

 2 lbs. 

 2 lbs. 



" The sublimate to be reduced to a fine powder, 

 and mixed with a portion of the oil, and also the 

 hellebore. The rosin, tallow, and the remainder of 

 the oil are to be melted together, and the other in- 

 gredients then added and well mixed. Should the 

 ointment appear too thin, the proportion of oil may 

 be diminished and the tallow increased." 



Before applying any remedies, the diseased parts 

 should be well washed in soap and water, applied 

 with a soft brush ; and, if the wool is started or in 

 the way, it should be at once cut off. 



Few animals suffer more from rhe attacks of va- 

 rious kinds of flies than the sheep, and none aie less 

 capable of avoiding their annoyance. There is the 

 Estrus ovis, which deposites its eggs in the nostril 

 of the sheep, from which it ascends to the cavities 

 of the head, producing constant irritation, and not 

 unfrequently death. This fly is the most common 

 in the latter part of July or August, and its presence 

 near a flock may be known by the animals instinct- 

 ivelj' placing their noses as near the ground as pos- 

 sible to keep off the enemy, listening to catch the 

 sound of his wings, and darting away, with their noses 

 rubbing the earth, to a distant part of the field, to 

 avoid the pursuit. Rubbing the end of the nose with 

 tar, or spreading salt on tar to be licked off, furnish- 

 es the best preventive against this fly that has yet 

 been discovered. 



Another fly deposites its eggs around the roots of 

 the horns and about the tail of sheep ; where, if un- 

 molested, they form deep ulcers, and the poor ani- 

 mal runs the r^sk of being devoured alive. Dr.
