When they finally meet, what is Utterson's reaction to Hyde?

When Utterson meets Hyde in Chapter 2, Utterson is
completely repelled by Hyde.  His reaction to Hyde can be fairly neatly summed up in one
line that Utterson speaks.  He says to himself

God bless me, the man seems hardly
human!

and then goes on to
say

...oh, my poor old Harry Jekyll, if

signature on a face, it is on that of your new
friend.

Utterson cannot
really understand why it is that he dislikes Hyde and is so repelled by him.  He thinks
about how Hyde looks a little bit strange and about how Hyde sounds strange.  But he
thinks that these things are not enough to account for how deeply disgusted he is by
Hyde.  He wonders if he just hates Hyde for no good
reason.

Utterson does not realize it at this point, but
what he is seeing (and being repelled by) is the fact that Hyde is purely
evil.
