Bunge's Improved Analytical Balance. (Chenz. Zed., 1896, xx., 32G.)-In the ordinary process of weighing much time is wasted, and considerable harm is done to the agate bearings by the oscillations of the beam during the earlier attempts at attaining a balance. This improvement consists in the addition of a separate arrangement under the left-hand (object) pan, by means of which the weight of the substance is read directly to the nearest gramme on a scale attached to any convenient spot in the

Underneath it is an agate point fastened to the arresting gear of the pan, which depresses to a greater or less extent an adjustable agate cup fixed to the shorter end of the lever-balance, the opposite extremity of which carries the pointer travelling over the scale. In the case of balances that are always swinging, enough space is left to permit of this inovement ; but in the other variety the addition is thrown in and out of gear by an eccentric. The improvement is patented in Germany.
