+ He can transform himself to wolf, as we gather from the ship
+ arrival in Whitby, when he tear open the dog; he can be as
+ bat, as Madam Mina saw him on the window at Whitby, and as
+ friend John saw him fly from this so near house, and as my
+ friend Quincey saw him at the window of Miss Lucy. He can come
+ in mist which he create--that noble ship's captain proved him
+ of this; but, from what we know, the distance he can make this
+ mist is limited, and it can only be round himself. He come on
+ moonlight rays as elemental dust--as again Jonathan saw those
+ sisters in the castle of Dracula. He become so small--we
+ ourselves saw Miss Lucy, ere she was at peace, slip through a
+ hairbreadth space at the tomb door.
