    Pl. 2. Fig. 2. is a Thermometer of the same kind, with this difference only, that the body is but six inches long, and of such a diameter as to contain the same quantity of spirit as fig. 1. and placed in a horizontal position, for the conveni- ence of applying it very near the ground, or sur- face of any other bodies. But as Thermometer fig. 1. pl. 2. may be placed to within 10 or 29 degrees of the horizon, I have found it rather more convenient for most experiments on or near the ground, than this.* These three instruments are essentially the same: the two first differing only in the size, and the form of their frames, the other in the horizon: tal position of the body, * This Thermometer is drawn withont a frame, that the disposition - of the tubes may be more distinctly seen. The frame may be made as best suits the experiments for which it is intended,
