tion by cocco-bacillus and later by streptococcus or some other com- 

 plicating infection, we can scarcely hope that the toxins of the 

 streptococcus or other complicating microbe will immunize against 

 the cocco-bacillus or mutually against each other. If complete 

 protection is aimed at, the toxins of his cocco-bacillus, and of 

 Schutz's streptococcus, and of any other possible microbe which 

 may produce a secondary complication, ought to be employed. 

 At the date of this writing no satisfactory sero-therapy for this 

 disease has been worked out and publicly demonstrated. 



INFECTIOUS STABLE BRONCHITIS. SCALMA. 



Definition. An infectious inflammation, of the upper air pas- 

 sages and bronchia, attended by high fever, special nervous 

 irritability and a protracted convalescence. 



DieckerhofI gave the name scalma (rogue) to outbreaks in 

 given stables of an infection, showing the high temperature of 

 brustseuche, ( 104° to 107° F.) a similar incubation (6 to 7 days), 

 a correspondingly tardy extension from animal to animal, and 

 duration of the disease. The apparent differences are in the 

 absence of the profound dullness, the yellowness of the mucosae, 

 and the yellow or rusty nasal discharge, in the ready response to 

 the voice or touch, the disposition to bite or kick, the spasms of 

 the larynx and sudden dyspnoea, in certain cases, and the paroxys- 

 mal cough in others. Apart from these transient respiratory 

 troubles the pulse and breathing are unaffected, relatively to the 

 elevation of temperature. Sometimes the jaws are kept in con- 

 stant motion, from nervousness or pharyngeal trouble. 



In the absence of any co&clusive bacteriological investigation, 

 it may be surmised that this is a form of brustseuche which has 

 not advanced to the same grade of destruction of red globules 

 and prostration of the nerve centres, the latter showing only an 

 excited and irritable condition. 



Treatment and prevention do not differ materially from what is 

 required in contagious pneumonia. The irritable cough may be 

 soothed by inhalations of warm water vapor, with alcohol, cam- 

 phor, eucalyptol, or opium, or electuaries of bromides, belladonna 

 or stramonium, and local derivatives to the throat. 



Most cases are mild and recover in a week, the cough lasting 

 for two weeks more.
