What is the role of syntax in this line? At this, after a second in which his head made the movement of a baffled dog's on a scent and then gave a frantic little shake for air and
light, he was at me in a white rage, bewildered, glaring vainly over the place and missing wholly, though it now, to my sense, filled the
room like the taste of polson, the wide, overwhelming presence.
(from The Turn of the Screw by Henry James)
