A male collie was admitted to the Stange Memorial Clinic on Oct. 1, 1945, with the history of having been shot through the neck. The symptoms observed were depression and incoordination indicating a central nervous disturbance. Upon examination a puncture wound about one-fourth inch in diameter was found on the left side of the neck in the region of the fourth cervical vertebra.
