In March, Adrian Saylor sold government bonds owned exclusively by him and with $6,450 of the proceeds opened a savings account in a bank in the name of ‘‘Mr. or Mrs. Adrian M. Saylor.’’ In June of the following year, Saylor deposited the additional sum of $2,132 of his own money in the account. There were no other deposits and no withdrawals prior to Saylor’s death a year later. Is the balance of the account on Saylor’s death payable wholly to Adrian Saylor’s estate, wholly to his widow, or half to each?
