AS its title suggests, the June 30 sale of scientific, medical and engineering works of art held by Christie’s South Kensington (19.5/12% buyer's premium) was something of a mixed bag. The 216-lot auction incorporated anything from 18th century microscopes and preserved amphibians to delft barbers’ bowls and scale models of locomotives.

Christie’s South Kensington (19.5/12% buyer’s premium) hold three Scientific Instruments sale a year but reserve the spring sale for a restricted number of high-quality objects. Tom Newth, head of the department, reports the market picking up in the last six months, with strong competition for microscopes and Islamic astronomical instruments.

A private collection of 99 microscopes was the highlight of this three-day sale at John Bellmans. No fewer than nine examples realised four-figure sums, the best seller being a 19th century lacquered brass binocular petrological microscope by Watson & Sons which sold to a private collector from London at £3100.
