4.— Paralysis of the Supra-scapular Nerve. 



Anatomy. — Formed by the sixth and seventh cervical 

 pairs, this short and tliick nerve runs backward between 

 the levator anguli scapulse on the one side, and the anterior 

 deep pectoral, prescapularis and antea spinatus muscles 

 on the other, gaining the space between the antea spinatus 

 and subscapularis, entering it. Now it bends around the 

 anterior border of the scapula, runs across the acromion 

 spine, ascending to the postea spinatus fossa. It supplies 

 the antea spinatus, postea spinatus and teres muscle. 

 (Chauveau.) 



History. — Lameness following runaways, colliding with 

 trees, posts, etc. 



Inspection. — Supporting - leg lameness, with sudden 

 abduction of the shoulder. By walking the animal toward 

 the observer it will be seen that the scapula, at the moment 

 the leg supports Aveight and is perpendicularly under the 

 body, suddenly is jeiked away from the tliorax. In disease 

 of some standing the scapular spine becomes prominent, 

 due to the atrophy of the paralyzed muscles, especially the 

 antea spinatus and the two abductors, the postea spinatus 

 muscle showing nothing abnormal. 



5. — Inflammation of the Bursa of the Flexor 

 Brachii Muscle 



Anatomy. — A long cylindrical muscle divided by many 

 strong fibrous intersections, the middle one of which is of a 

 tendinous nature, being continuous with the tendon of the 

 muscle at the extremities. It originates at the base of the
