modification can be found. The complication of gastro-enteritis 
weakens the patient. Cerebral spinal meningitis, hemorrhage into 
the interior of the eye, and arthritis may occur. The detailed descrip- 
tion of many of the variations as described by Dieckerhoff are worthy 
of careful study. 
Diagnosis. Brustseuche is diagnosed by its symptoms. There 
are no satisfactory specific tests. It is to be differentiated from 
influenza when the localization of the lesions in the lungs does not 
occur; bronchial pneumonia which often follows colds; and the 
pneumonia following the introduction of foreign substances into the 
lungs, as often happens in giving medicines. The history, course of 
the disease, and the spread to other animals will do much to settle 
the diagnosis. 
Prevention. The well animals should, if possible, be removed at 
once to other stables. The stalls occupied by the infected animals 
should be disinfected before being used for other horses. Isolation 
and disinfection are the important factors in checking the spread of 
this, as of other infectious diseases.
