traordinary, viz., the ability to squirt blood, or what seems to be 
blood, from the eyes. Dr. Giinther has said, however, that 
‘“‘ nothing has been found, on anatomical examination, to establish 
the correctness of this assertion.” Personally, I have never seen

signs on a specimen of my own which led me to believe that he
