Cylindrical tube piece of machinery with lens and coated in olive green enamel. Gauge measure visible.

Metal engineering piece showing circular measuring dial. Other dials visible. Lens also included.

Information sheet next to object details history, purpose and use. A pillar was constructed for the instrument in 1863.Heliostat consisting of brass cylindrical body on metal stand.Engraved on face: “J.C. Silbermann Invleur Tuit por J.Dubosq i Paris” “No. 119”

Declination instrument consisting of metal horizontal cylinder erected on brass three legged stand. A wooden rectangular box forms part of the instrument from which a horizontal telescope emerges (measurement of geographical meridian) and a vertical glass tube containing the suspension for the hollow magnet.Engraved on cylinder: “Elliott Bros London No.71”

Dip circle consists of a brass cylinder with two glass flat end-windows, containing a centrally mounted magnetic needle free to rotate about its supporting axis in a vertical plane. The needle , when at rest is arrested by a trunnion from which the needle can be raised by means of external knob. Very close to the needle is mounted the vertical circular scale. Two magnifiers are mounted at the end of a brass “diameter’ which can be rotated so as to read off the angular positions of both ends of the needle after being set up. Graduated horizontal scale on the base. Spirit level mounted. Tribach base.Engraved on base: “Robinson 38 Devonshire Street Portland Place London”

Dip circle has much the same elments as in the previous model ( cat. no.81), except the brass cylinder is replaced by a mahogany box with two end windows. Tribrach base is fixed into a wooden sheet ( maybe for ease of carrying in the field).Label: “Nat Phil Lab No. Univ. of Melb” Magnets inscribed “Magnets for dip”
