continuously, is driven to town afternoon of March 31, and tied to a locust tree which is 

 6-8 inches in diameter; owner noticed that animal had peeled bark from tree also noticed

 when a faint noise was heard this gradually grew worse until I arrived at 7 a. m. April 1. 

 Symptoms: 1. Animal stands back from manger with legs well apart resting nose and 

 mouth on floor, most of the time, a part of the time head is held 18-24 inches from floor. 



2. A continual "thud" is heard which is not synchronous with respiration but is 

 synchronous with a vibration of thorax.

 muffled but very loud. (Palpitation).
