RESPIRATORY DISEASES 141 



illustrates the course and treatment of colds in 

 birds : 



With the advent of cold weather, early last fall, a large 

 number of our chickens contracted colds, which was ex- 

 tremely discouraging, to say the least. We had over one 

 hundred chickens, besides turkeys, and fully twenty-five per 

 cent were affected at one time. In addition to the colds which 

 affected the throat, nostrils and eyes, many were affected 

 with canker in the mouth. The ordinary remedies, kerosene, 

 roup cures, etc., were all used, with little effect. We finally 

 secured from the drug store (at the suggestion of Doctor 

 Kaupp) some sulphocarbolates compound tablets and used 

 them, but the improvement was not very marked. Later 

 tablets furnished by the Pathological Laboratory of the Colo- 

 rado Agricultural College (sulphocarbolates compound, thirty 

 grains, with six grains bichloride of mercury to the tablet) 

 were tried. This was not only placed in the drinking water, 

 but a solution was used in a syringe to wash out the nos- 

 trils and mouth. This treatment was marvelously effective. 

 It acted like a charm. The catarrhal condition continued, 

 however, until the following treatment was used (also at 

 the suggestion of Doctor Kaupp) : 



The nostrils were washed out with a twenty per cent solu- 

 tion of common baking soda; then with peroxide of hydrogen, 

 and finally with the following preparation: Oil of eucalyp- 

 tus, twenty drops; oil of thyme, one dram, and petrol oil, 

 two ounces. A warm solution of the soda was always used 

 and the other materials were warmed by setting the bottles 

 in hot water. This treatment was also applied to the eyes,. 

 and the ulcers in the mouth were swabbed with it. The re- 

 sults were remarkable. It was almost impossible to make a 

 record of these cases, as a large portion of the flock were 

 affected. Furthermore, it was impossible to give them all 

 the daily treatment prescribed. Sometimes they would go 

 several days without treatment. In mild cases, however, from 

 two to three applications affected a cure. 



March 17th we found a young cockerel in a very roupy 

 condition. He had been hatched late in the fall and had 

 never been very vigorous. His eyes were swollen shut, 

 nostrils discharging badly, and, with all, his was not a prom- 

 ising case. We isolated him and gave him the regulation 

 treatment, as described above. Notwithstanding that it 

 stormed severely and he was not well feathered, the next day 

 he was showing a decided improvement, and after three treat- 

 ments, covering about five days, all evidence of the trouble 

 had disappeared and to-day he is apparently in better con- 

 dition than at any time during the winter. 



A day or two later we found two others belonging to the 

 same brood in about the same condition and after one treat- 

 ment there was evidence of improvement, but after a few 

 days, not having been able to give them careful attention
