Theelongation occurred about the 3d of the above 6 consecutive measures. PART IV.

Parts II and III contain tlie necessary stateniuiUs and results for the next (jperation,namely, the direct comparison of the astronomic latitudes, longitudes, and azimutliswith their corresponding values derived geodetically by development of the triangulationupon the Clarke spheroid of iS66. In doing this the geodetic data for the stationHays, Kansas, as given in the account of the transcontinental triangidation and arc ofthe parallel in latitude 39°, have been adhered to.
