slipping

And I worshipped the Lord God of Israel, and bade another demon come forward. And there came before me a dragon, three-headed, of fearful hue. And I questioned him: "Who art thou?" And he answered me: "I am a caltrop-like spirit, whose activity in three lines. But I blind children in women's wombs, and twirl their ears round. And I make them deaf and mute. And I have again in my third head means of slipping in. And I smite men in the limbless part of the body, and cause them to fall down, and foam, and grind their teeth. But I have my own way of being frustrated, Jerusalem being signified in writing, unto the place called 'of the head." For there is fore-appointed the angel of the great counsel, and now he will openly dwell on the cross. He doth frustrate me, and to him am I subject."
