The National Museums of Scotland invited me to display my collection of early navigational instruments at the launch of the 350th anniversary of the Royal Society, held in the National Museum of Scotland on 30 November, 2009. The image shows my instruments next to the replica's the museum was able to commission thanks to funding by The Royal Society.
The inset shows a full view of the table with from left to right: Master Hood's cross-staff, the Kronan Cross-staff, the spiegelboog (mirror-staff), instruments for electrical experiments, the demi-cross, a weather glass, telescope and lodestone, the hoekboog (double triangle), a globe, the Davis quadrant, a magic lantern and the Hasebroek cross-staff.
