This object consists of a theodolite in a rectangular wooden box (2016.ihpst.34.1) and a tall surveying tripod (2016.ihpst.34.2) onto which the theodolite can be mounted.
The theodolite consists of a long, black telescope-like tube mounted horizontally. Directly underneath there is a long graduated spirit level containing water. These two are mounted on a solid black base with four adjustable leveling screws. Underneath the screws there is a round cylindrical base with a screw interior for attachment for the tripod. One brass knob is attached to the telescope and adjust the focus. Another is attached to a plate underneath the spirit level.
The box is rectangular with a flip-up lid. Inside the box there are sections for storing various attachments. One section contains a brass case which contains a item shaped like a ring with four pieces screwed into it, and then two metal rods. Another contains a piece of beige packing material. At the other side, there is a section with three cylindrical holes –the centre one holds a small lens; in this section there is also a small key. A final section holds a graduated glass cylinder with water inside, possibly a spirit level.
The tripod is made of wood and each foot has a pointed brass end. On the top of the tripod there is a cylindrical attachment with screw threads on the outside, for attaching to the base of the theodolite.
