This description was taken from an adult male captured near Eastchester, about fifteen 

 miles from the city. It made considerable resistance, emitted a bellowing noise when 

 attacked, and exhibited no symptoms of fear. 



This is an inhabitant of the northern regions, having been seen as high as the seventieth 

 parallel. The preceding must be considered as the first notice of its existence within our 

 territorial limits, where it can only be regarded as a rare and accidental visitor.
