1an effect very intense and pronounced. The post acts like the bow, and produces a shock corresponding to each vibration produced by the latter. It is to be noted that the nature of the deal renders the transverse flexions of the belly more easy. In fact, if care is taken to place all the fibres of the wood parallel to the greatest length of the instrument, vibrations, whose direction is at right angles to these fibres, will produce more decided flexions than if it were in any other direction, for in this direction the elasticity of the wood is the smallest. It is necessary, therefore, that the fibres of the deal should be placed parallel to the length of the instrument. The post has other properties besides that we have just attributed to it. It is not placed inside the violin to sustain the belly, since we can place it outside the instrument; besides, so slender a rod of dry wood would be of little use for strengthening purposes. It plays a very important part, which proves the necessity of giving to the bridge a certain definite form. It is always placed behind the right foot of the bridge, which has the effect of sustaining this foot in a state of almost perfect rest, in order that the left foot may, as in the marine-trumpet, communicate its movements to the bar of the instrument. In all violins there is beneath the belly a bar intended to give the belly resistance, at the same time that it determines in the whole length of the instrument the movement communicated to it. This bar is to the left of the instrument, and ought to receive the shocks produced by the left foot of the bridge.
