The first observation I attempted of this kind was with a view to one of the objects, which. made me desirous of having an hygrometer These objects are all comprized in a general system concerning vapours, which I have given in my work upon the Modifications of the Atmosphere I shall therefore only mention here one particular consequence of that system, which it was my immediate point to verify ; namely, that a certain augmentation of heat, we always perceive at every season upon the approach of rain, is owing to a more than ordinary quantity of vapour ; and that, on the contrary, it is to their diminished quantity that the lesser heat of the upper parts of the atmosphere is in great measure to be ascribed.
