respiration, be carried into the air passages, and thus destro.y the filarire. 

 In some cases it must be repeated two or three times, but once has 

 frequently the desired effect. 



The method of treatment by intra-traeheal injection, introduced by 

 Levi, of Pisa, has yielded very satisfactory results. Levi has been com- 

 pletely successful with a sheep. Eloire has employed it in sixteen calves 

 affected with the disease, and all were cured. He used the following 

 mixture : Black poppy oil, 100 parts ; oil of turpentine, 100 parts ; car- 

 bolic acid, 2 parts ; purified cade oil, 2 parts. Each calf received 10 

 grams of this mixture daily for three days. 



The injection, which should be given slowly, is followed by a fit of 

 coughing, and the expired air has the odour of turpentine. This treat- 

 ment has also been successful at Milan. Similar favourable results have 

 followed Button's treatment of eight calves, some of which were in the 

 last stage of verminous bronchitis. He employed a mixture of oil of 

 turpentine, tincture of opium, pure carbolic acid, and water — the oil 

 of turj^entine forming one-half of the mixture. The dose was ^ an 

 ounce, and in the serious cases this was given every day for three days, 

 and in other cases every second or third day. Kriwonogow has likewise 

 cured twenty- two calves by giving each of them two tracheal injections of 

 8 grams of the following mixture : Essence of cloves and oil of turpen- 

 tine, 3()0 parts of each ; carbolic acid and olive oil, 30 parts of each. 



(Williams speaks highly of the administration of prussic acid. 

 Penhale gives — by intra-tracheal injection, and slowly — oil of turpentine 

 2 drams, carbolic acid 20 minims, and chloroform ^ a dram.)
