Confectionery.—We have received from J. B. Hennegan & Co., wholesale confectioners, 17 South Clark street, a box of assorted and most delicious confectionery, free from adulterations of any kind. We have never seen confectionery superior to this, and can confidently recommend it as A No. 1, to all who have sweet teeth, and to dealers everywhere as a being genuine and unsurpassed article.
