2. Why the Barometer does not always indicate the Real Weight of the Mass of Atmosphere aloft. A continuation of the Paper on this subject laid before the Society in Session 1876 and 1877

Extract
Meteorological phenomena are in all cases to be regarded as being both a cause and an effect; owing to this, and also to the imperfect state of our knowledge on this subject, it may be safely asserted that exception proves or tests the rule. Taking up the subject in this point of view, much assistance is in this way to be acquired when attempts are made to explain the phenomena which are under consideration, and hence these negative conclusions can to a large extent be taken advantage of. As an illustration of this, can it be assumed that a barometer placed on the surface of the earth, and which always correctly indicates the amount of pressure on its cistern, will also always correctly indicate the weight of the mass of air aloft, both when it is at rest and when it is in rapid motion, accompanied by the important element of friction.
