Theodolite
Object Details
- E. & G. W. Blunt
- Description
- This unusually small theodolite with an "E. & G. W. Blunt New York" inscription was probably an English instrument that the Blunts imported soon after beginning in business in 1824. It may also be one of the surveying instruments that the Rensselaer Polytechnic Institute acquired soon after that school opened in 1824.
- The horizontal circle has a beveled edge that is silvered, graduated to 30 minutes, and read by opposite verniers to single minutes. The vertical arc is silvered, graduated to 30 minutes, and read by vernier to single minutes.
