what two things surprise Mr. Utterson about the will found on Dr. Jekyll's desk?

From the text:

"On the desk, among the neat array of papers, a large envelope was uppermost, and bore, in the doctor's hand, the name of Mr. Utterson. The lawyer unsealed it, and several enclosures fell to the floor. The first was a will, drawn in the same eccentric terms as the one which he had returned six months before, to serve as a testament in case of death and as a deed of gift in case of disappearance; but in place of the name of Edward Hyde, the lawyer, with indescribable amazement read the name of Gabriel John Utterson."
