To quickly assess the difficulty of the text, read a short excerpt:
The pressure of the steam acts against a yalye which is connected with the arm of the lever of the steel-yard, the other arm being connected with the spring. In this way the varying tension of the spring is made to measure ihe pressure on the valve. When steam of low pressure is used, an expedient called a mer- curial steam gauge is used. A bent tube containing mercury is inserted into some part of the apparatus, which has free commu- nication with the steam. Let ABC (fig. 6), be such a tube. T...he pressure of the steam forces the mercury down in tiie leg a b, and up in the leg B c. If the mercury in both legs be at exactly the same level, tiie pressure of the steam must be exactly equal to that of the atmosphere ; because the steam pressure on the mer- cury in A B balances the atmo- spheric pressure on the mercury in B c. If, however, the level of the mercury in b c be above the level of the mercury in B A, the pressure of the steam will exceed that of the atmosphere. The ex- cess of its pressure above that of the atmosphere may be found by observing the difference of the level of the mercury in the tubes B c and B A, allowing a pressure of one pound on each square inch for every two inches in the difference of the levels.
