TRACES OF THE ACTUAL OBSERVATIONS

ON THE TRIANGULATION STATIONS AROUND THE GREAT PYRAMID.

Traces Actual Size, i.e. shewing the actual lineal differences of the observations From the mean stations found by graphic adjustment.

Distances of stations apart, Scale 1 to 1800.

Angular differences therefore 1/2" here to 1” in field.

Circles around stations = probable error of places of stations, by traces as here shewn.

Full Lines = Direct Observations.

Dotted Lines = Reflex Observations.
