IMPROVED ENEMA SYRINGES, with Metal Pistons, for use in warm climates, where the ordinary Pistons become hard or unfit for use. These Syringes are not only superior from their durability, but more perfect, more easy in their action, and much better adapted for the use of invalids.
PATENT CORK NIPPLES FOR SUCKLING, AND BOTTLES FOR FEEDING CHILDREN.—This elegant invention possesses the most decided advantages over all the artificial Nipples at present in use; they are perfectly free from the impurities and the injurious effects of the prepared calves' teats, or those made of elastic gum. They are made of the finest cork, prepared for the purpose, presenting a smooth velvety surface to the lips; and, although supple and elastic, they are so firm that there is no danger of their collapsing from the pressure of the gums.
WEISS'S IMPROVED SCISSORS WITH ECCENTRIC OR LEVER JOINTS.—The joints of these Scissors being placed at the side, instead of in the centre as usual, cause the blades to cross diagonally, and thus a drawing cut is obtained, similar to that made by a knife. By this means the power of the Scissors is greatly increased, not only by the additional leverage obtained by the position of the joints, but by the sliding action of the blades on each other. This has long been a desideratum in Scissors, not only where power is required, but even for the lightest work. Every description of Scissors is made upon this improved principle.
