RESIEDIES ADMINISTERED INTERNALLY. 



The above measures have reference to the safety of uninfected aui- 

 iiials. The treatment to be resorted to when the existence of vermin- 

 ous bronchitis has been determined, and it is not desirable to destroy 

 the diseased animals, must be directed, first, towards supporting the 

 strength of the animal, and second, towards the destruction of the para- 

 sites. 



Good nourishing food is therefore always indicated. A recent writer 

 suggests the use of garlic, which Megnin found so efficacious in the 

 treatment of the gapes. (See First Annual Report of the Bureau of 

 Animal Industry, j). 294,) This should be mixed with the food. Medi- 

 cal treatment has been of various kinds. The internal administration 

 of remedies has been much employed, together with the inhalation of 

 volatile, irritant substances, supposed to have a direct toxic action ui)on 

 the parasites. Lately, the method of injecting liquids into the trachea 

 has been suggested, and veterinarians are very hopeful of its success- 

 ful application in the future. First, as regards internal remedies, the 

 following mixture seems to enjoy considerable favor among European 

 veterinarians :

Asafoetida - — - 30 



Emijyreumatic oil of Chabert - -. - - - 60 



Mucilage • 500 



One teaspoonf al dailj'' in milk. 



The oil of Chabert, however, is not in the market in this country, 

 making the formula useless. Among other remedies, creosote has been 

 given diluted in water, G3 grams (about 2 ounces by weight) being 

 distributed to 100 sheep. Benzine and picrate of potash are among 

 those recommended. Eecently a writer {Recueil de Med. Yet, 1884, p. 

 2G) reports recovery of 150 cases of verminous bronchitis in calves dur- 

 ing a period of three years under the following treatment : 



Give, according to size, 10 to 15 centigrams (1.5 to 2.3 grains) of 

 sulphate of strychnia daily in water. This quantity must be divided 

 into three or four doses, as strychnia is ver^^ poisonous. In addition to 

 this, Irom 10 to 15 grams (2^ to 4 drachms) of sulphide of calcium are 

 given in oats or bran. 



To attack the parasites directly in the air-passages inhalations and 

 fumigations have been much resorted to. 



The affected animals are placed in a closed building and the medi- 

 cines vaporized by means of heat. This can be accomplished by pour- 

 ing them upon heated stones or iron. Crude carbolic acid and tar have 

 been employed in this manner. Certain other recommended substances, 

 among them turpentine and ether, which are inflammable, must be used 

 with care, and ordinarily are converted into vapor without the use of 

 heat. Snlphur may be burned in an iron receptacle. In these fumiga- 

 tions care must bo taken that they do not prove too irritating to the 

 air-passages. Several fumigations must usually be practiced to be of 

 any benefit. Strebel recommends a mixture of one part of turpentine 

 and thirty parts of ether, to be dropped into the nostrils of the affected 

 animal. Knowing the irritating effects of ether on the mucous mem 

 branes, it is questionable whether such treatment would accomplish 

 anything beyond causing severe coughing. 



TRACHEAL INJECTIONS. 



Probably the most promising medication which is now being tried is 

 the direct injection into the trachea of liquid medicines known to have
