What does this mean?
“it is true this government is limited to certain objects, or to speak more properly, some small degree of power is still left to the states, but a little attention to the powers vested in the general government, will convince every candid man, that if it is capable of being executed, all that is reserved for the individual states [must] very soon be annihilated, except so far a[s they are] barely necessary to the organization of the general government.“

This enquiry is important, because, although the government reported by the convention does not go to a perfect and entire consolidation, yet it approaches so near to it, that it must, if executed, certainly and infallibly terminate in it.

uses : -

1.aneroid barometers primarily measure whether pressure is rising or falling.

2.aneroid barometers are often used for reading pressure in homes and recreational boats.  

3.other uses may include barographs in meteorology and altimeters in modern aircraft.  

4.this type of barometer can announce whether a high or low pressure system is coming or whether it is becoming more intense.  

5.there are different types of aneroid barometers, such as the altimeter, which measures altitude, or distance above sea level.  

6.another example is a barograph, which is a modified aneroid barometer that provides constant readings of atmospheric pressure on graph paper.  

7.when used in this capacity, the aneroid barometer can store a week's worth of data.

android diameter a device for measuring atmospheric pressure , often specially calibrated for use as an altimeter ,consisting of a box or chamber partially exhaused of air, having an elastic top and a pointer to indicate the degree of compression of the top caused by the external air
