Wright and Hayford: Adjustment Of Observations. Some of the simpler cases are treated first, such as the local adjust ment at a station, the adjustment of a simple quadrilateral, etc. After these is given the development of the condition equations for latitude and longitude closures, followed by a sample adjustment including the condition equations for these closures, together with the equations for length and azimuth conditions. A method of adjustment by the variation Of geographic coordinates is then developed and applied first to a quadrilateral, then to a figure with a few new points connected with a number Of fixed points. The same method is applied to the adjustment of a figure with lati tude, longitude, length, and azimuth conditions. A sample adjust ment of a vertical net is carried through and lastly there is given the development of the formulae for the computation Of vertical Observa tions, together with examples of the method of computation.8 coast and geodetic survey special publication no. 28.
