Description: | Circular wooden base with 3 protruding adjustable feet, draught shield made of perspex fits into groove on base. Glass top of shield cracked. Torsion head mounted centrally on shield with 360 degree scale on top calibrated in degrees. Thin suspension broken so that suspended rod no longer hangs (but could be easily repaired). At one end of rod is gold-leaf ball and at other black air-damping paddle. Central brass plaque on base reads ABDN. UNIV. NAT. PHIL. And on underside of base maker's brass plaque W. Ladd & Co. 11 & 12 Beak Street, Regent Street. This item was one of the live demonstrations in the Museum in Fraser Noble in the 1970s and the varnish on the wood and the polish on the brass suggest it was fully restored at that time. | License: | http://www.abdn.ac.uk/historic/Copyright_terms_conditions.shtml | Publisher: | ABDNP University of Aberdeen, Natural Philosophy Collection of Historical Scientific Instruments | Rights holder: | 47718 | Temporal: | 1850-1870 | Source: | University of Aberdeen | Creator: | W.
