small dog. The powder is to be rubbed up with butter. Follow iu two 

 hours by a table-spoonful of castor-oil. 



Dr. Hagen advises treatuieut of all sheep dogs each spring and fall, 

 thereby claiming an increased immunity for the sheep from the cysticerci. 

 He recommends the ibllowing: Take of the oxide of copper 80 grains, 

 of powdered clialk and Armenian bolus 40 grains each ; of water suffi- 

 cient to mix the ingredients into an adherent mass; divide into one 

 hundred pills; administer one three times daily for ten days by crush- 

 ing them in a piece of meat or bread and butter. 



In addition toother remedies lioll prescribes the following: (Each 

 dose is for large dogs. For smaller ones pro[)ortionately less ought to 

 be given.) (1) Extract of male fern and the powder of male-fern, 13 

 drams each. (2) A decoctiou of 3i ounces of pomegranate-root bark in 

 water, reduced to G fluid ounces, and add 1 dram of extract of male-fern, 

 to be given in two doses an hour apart. (3) From one-half to 1 ounce 

 kousso formed into pills with honey or molasses, and a little meal. (4) 

 From 1.^- to 2i drams of Kamala stirred with honey or water, and given 

 iu two doses inside of an hour. lie advises a preliminary preparation 

 by feeding the dogs sparingly for two or three days previous on salted 

 food, and the administration of castor-oil the evening before. The rem- 

 edies proposed are to be mixed with some material to make them fairly 

 acceptable to the patients. With the exception of kamala, which acts 

 as a cathartic, all should be followed in two hours by castor-oil. 



After any treatment the patients should be fed with some liquid diet 

 on the first day. After this they may receive any wholesome food. 



The necessity of repeating a treatment depends entirely on the 

 efficacy of the first, and the care exercised in preventing a re-infection. 

 If the treatment has been successful in removing the worms, heads and 

 all, of course no further treatment will be required. If only portions 

 have been removed, then another dosing is necessary. For ta'iiia mar- 

 ginata another treatment need not occur under eight weeks, for the 

 tape- worm is liarmless as far as sheep are concerned up to that period, 

 for, as far as is known, the worm will not throw off segments before that 

 time. For T. cacnurus the treatment should be repeated in about two 

 weeks. 



Frerentive treatment — The great resource of the flockmaster lies in 

 prevention. In this he has nearly absolute control over the health of 

 his sheep, in so far as Tccnia marginata and T. coenurus are concerned. 

 As the dogs can only get these taniia from eating viscera of the sheep, 

 all the viscera of slaughtered or dead sheep should be withheld from 

 them, and either buried, burned, or rendered. 



Police sanitation. — Sheep-killing dogs should be destroyed. Each 

 owner should keep his dogs at home, so that all strange dogs may be 

 killed in order to prevent them from harming sheei) and scattering the 

 tiTBuia eggs far and wide over the pastures and in the drinking jdaces. 

 Dog laws ought to be made sufficiently stringent and adequate for the 

 protection of sheei).
