GENERAL DISEASES. 1071 



What to do. — The grubs may often be extracted by a competent sur- 

 geon, but it is a nice operation, and scarcely pays except in the case of a 

 very valuable animal. Burning leather under the noses of the sheep in a 

 close place, to cause violent sneezing, used to be practiced, but it is un- 

 safe. Injecting up the nostrils equal parts of sweet oil and turpentine 

 will often dislodge the grubs when they are not firmly fixed, but care 

 must l)c taken not to strangle the sheep. 



Prevention. — Prevention is ia tiiis case far the best remedy. Keep a 

 portion of the field plowed so the soil is loose and dry. Smear the 

 sheep's noses once a day with tar during the season of the fly, and catch 

 as many of the flies as possible, by means of a light bag-net. The most 

 convenient way to apply the pine tar, in case of large flacks, is to smear 

 the inside of the salt troughs with it; then they will smear their own nores 

 while eating the salt. 



V. Hydatids on the Brain. 



Causes. — The bladder worm, causing this dangerous disease, is one of 

 the forms of the tape worm of the dog, the tenia serrata, preceding the true 

 or sexually i)erfect worm. It is rare in America, probably from the fact 

 that there are fewer dogs in proportion to the population than in England. 



What to do. — Once fixed, nothing practically can be done, though, 

 when located, surgeons have pierced the cysts with a strong hypodermic 

 syringe, injecting therein half a teaspoonful of the following: 



No. 2. 1 Grain iodine, 



5 Grains iodide of potash, 

 1 Ounce water. 

 Mix. 



Prevention. — Never allow dogs to feed on sheeps' heads, or other gar- 

 bage, unless cooked in the most thorough manner, remove the excre- 

 ments of dogs wherever found in the pastures, and kill all dogs that 

 make a habit of prowling about, away from home. 



VT. Apoplexy. 



This disease is mostly confined to sheep that are plethoric and fat. 



What to do. — The sheep will leap suddenly in the air, fall, and unless 

 promptly relieved, will die in a few minutes. Then the only remedy is 

 sudden and copious bleeding from the jugular vein. 



Prevention. — Fat sheep should be carefully watched for the earlier 

 symptoms. If a sheep appears dull and partially unconcious of what is 

 going on ; if the nostrils and pupils of the eyes are dilated, and the 

 membranes of the nose deep red or violet ; the pulse hard and the breath- 

 ing stertorous, bleed immediately and give afterwards two ounces of 

 epsom salts, to be followed by an ounce every six hours, until a full 

 evacuation takes place from the bowels.
