A PLEASANT SUMMER BEVERAGE. – We have had an opportunity of testing the merits of a very delightful preparation of Cream Soda, put up in bottles, and sold by Mr. D. W. DAVIS, American street, near Line. This drink has been approved by medical men and army officers as being wholesome and simple in its ingredients, and being of [home?] manufacture, should be literally patronized by those who are fond of a pure and refreshing draught. The price is only ten cents per bottle, each bottle containing two glasses. Try it.
