Michael Ayrton (British, 1921-1975)Lens numbered '6/12' (to base of sculpture)bronze with a light brown patina and perspex, on a wooden base35cm (13 3/4in) high (including base); 31cm (12 3/16in) high (excluding base)Conceived in 1973Footnotes:ExhibitedSomerset, Bruton Gallery, Michael Ayrton: Recurring Themes and Images, 28 March-2 May 1981, no. 46 (another cast), illustratedThe present lot is offered together with a copy of the above exhibition catalogue.Lens is from a series of sculptures which Ayrton called Reflectors, where he brought together one of the oldest man-made materials (bronze) and one of the most recent (neutral-density Perspex) in sculptures which continue to explore the theme of mazes and extend the concept to include the maze-like perceptual effects that can be produced with mirrors. Perspex has the unique characteristic of being simultaneously transparent and reflective and Ayrton discovered that by placing bronze figures either side of a vertical Perspex sheet set into a bronze base and then rotating the sculpture on a turntable the figures could be made to interpenetrate and overlie each other in a complicated mirror-ballet of real and virtual images. In Lens, one of the latest of the series, the Perspex sheet is inset with a biconvex lens, which changes the reflective effects, and adds additional complexities of scale and position to the dance of the figures until it is almost impossible to believe that only two among the multitude are real.We are grateful to Dr Justine Hopkins for her assistance in cataloguing this lot.This lot is subject to the following lot symbols: ARAR Goods subject to Artists Resale Right Additional Premium.For further information on this lot please visit Bonhams.com

Higginson, possibly his father, another rule stamped NEGRETTI & ZAMBRA LONDON and H.P.HIGGINSON, although not marked with his name are 2 other instruments from the same family, a Compass Clinometer by Casella, English, c.1890, in oxidised and bright lacquered brass, signed 'L Casella London, with telescope, in fitted leather case, and an earlier French clinometer signed L'ing ChavallierOpticien, Paris (a lot) Harry Pasley Higginson (1838–1900) was a British and New Zealand civil engineer known for his significant contributions, including the construction of the Wellington and Manawatu Railway Company (WMR) line from Wellington to the Manawatu during the 1880s. The WMR was a privately-funded project since the government opted not to undertake its construction. Additionally, Higginson played a key role in the discovery of Dodo bones on the island of Mauritius in 1865. Higginson was born in Thormanby, North Yorkshire, England, in 1838, and received his education at the Collegiate School in Leicester. In his engineering career, he completed an apprenticeship under Sir William Fairbairn in Manchester, followed by railway, canal, and waterworks projects in Russia (1860–1861), Mauritius (1862–1866), England, and India. While in India in 1868, he became an associate member of the Institute of Civil Engineers, later attaining full membership in 1871. In 1872, Higginson was appointed as the superintending engineer for railways and public works in the South Island. In 1878, he transitioned to private practice in Dunedin and gained recognition for his work on the Kawarau Gorge Suspension Bridge, earning the Telford Premium from the Institute of Civil Engineers. This iconic bridge was finished in the late 1880s, serving as a vital access route to the Central Otago goldfields during that era. However, in 1963, traffic was rerouted to a new highway bridge on State Highway 6. The significance of the suspension bridge is underscored by its classification as a Category I historic place by the New Zealand Historic Places Trust. Today, it stands as a popular tourist attraction, offering commercialized ziplines and bungee jumping experiences for visitors seeking adventure amid its historic and scenic surroundings In 1882, he was contracted as the chief engineer to complete the Wellington to Manawatu Railway, which he accomplished nine months ahead of schedule. He was awarded his promised bonus four years later. Higginson's final appointment was as the engineer-manager of the Wellington Gas Works. Regarding the discovery of Dodo bones, in 1865, while working for the Government Staff of the Mauritius Railways, Higginson encountered workers extracting bones from a swampy area called the 'Mare aux Songes.' He recognized the significance of these bones, suspected to belong to the Dodo bird, which was thought to be extinct. Higginson's discovery led to further investigations and the dispatch of a substantial quantity of bones to institutions such as the British Museum, Liverpool, York, and Leeds Museums. These bones contributed to the understanding of the Dodo bird and are still held by World Museum Liverpool, The Yorkshire Museum, and Leeds Museums and Galleries. Harry Pasley Higginson passed away in Wellington on February 26, 1900, at the age of 63, and he was laid to rest in the Karori Cemetery. His memory is honored with a stained glass window at the Wellington Cathedral of St. Paul, featuring depictions of the Kawarau Gorge Suspension Bridge and a Dodo.

Tayloy, Tay, taggers, Tom Document - Obituary Dr T. H. C. Taylor, who died on April 14, 1972, 1 was a leading tropical entomologist and a pioneer of the biological control of insects leaving an enduring impact through his pioneering work on biological control of insects. After graduating with first-class honors in zoology from the University of London in 1924, Taylor's passion led him straight to Fiji, where he embarked on groundbreaking research. In his quest for effective insect control, he traveled extensively throughout Melanesia, Eastern Asia, and the West Indies, collecting suitable parasites and gaining invaluable insights into the diverse challenges of tropical entomology. Taylor's approach, which involved introducing natural predators and parasites to combat destructive pests, challenged conventional methods and established a promising alternative to the widespread use of harmful insecticides. His work laid the foundation for a new era of entomology, inspiring further exploration and advancements in the field. In Fiji, Dr. Taylor took on the coconut moth (Levuana iridescens) problem by introducing the Malaysian fly parasite (Bessa remota). This successful intervention prompted him to further establish the eulophid wasp (Pediobiu.v parvulus) to control the coconut leaf-miner and the coocinellid beetle (Cryptognatha nodiceps) to manage the coconut scale insect. These introductions effectively eliminated these serious pests, thanks to Taylor's hands-on field studies and skillful breeding techniques. Moreover, Dr. Taylor's early research in Trinidad on the thrips (Liothrips urichi) led to a successful control of the pasture weed (Clidemia hirta) in Fiji. By utilizing this natural predator, he demonstrated the potential of biological control as an alternative to harmful insecticides. This approach, which had already been pioneered in California and Hawaii, holds significant relevance today, given the growing global concern over the impact of insecticides on the environment. In his notable publication, "The Biological Control of an Insect in Fiji," Dr. Taylor made a significant contribution to the establishment of biological control as a credible and effective method. He provided valuable insights into the techniques of breeding and deploying predator and parasitic insects in controlled environments. This knowledge formed the foundation for future advancements in the field. In 1935, Dr. Taylor presented a paper in the Jubilee Proceedings of the Association of Applied Biologists, expressing his belief that biological control rarely succeeds in continental areas and is incompatible with chemical use. At the time, his assessment seemed accurate. However, subsequent developments and techniques have proven that biological control can be effective even in continental regions, challenging Dr. Taylor's initial viewpoint. Nonetheless, his early work remains crucial in driving our understanding and exploration of biological control methods.

The stand alone was 575 marks, by comparison, their cheapest microscope was 50 marks for the IX stand Sir Isaac Lowthian Bell: The Victorian Ironmaster, a Pioneer in Metallurgy and Industrial Innovation. Sir Isaac Lowthian Bell, 1st Baronet and LL.D., was an important player in the industrial landscape of 19th-century Britain. Born on February 15, 1816, in Newcastle-on-Tyne, Bell was the son of Thomas Bell, a partner in the firm of Messrs. Losh, Wilson, and Bell, and the grandson of Isaac Lowthian of Newbiggin, Cumberland. His remarkable journey in metallurgy and chemical engineering would shape the nation's industrial progress and scientific understanding. Bell's entrepreneurial spirit led him to take charge of the Walker Ironworks following his father's passing in 1845. This laid the foundation of a multifaceted career that would span several pioneering endeavors. In 1850, a significant breakthrough occurred when Bell, along with his brother-in-law Robert Benson Bowman and his father-in-law Hugh Lee Pattinson, established a chemical company in Washington, County Durham. Here, they developed a novel process for manufacturing lead oxychloride, a significant advancement for the chemical industry. This venture necessitated Bell's resignation from his position at Losh, Wilson, and Bell, showcasing the complexities of his multiple partnerships. Bell's appetite for innovation extended to engineering and in 1850, he partnered with Robert Stirling Newall to establish the world's first factory capable of manufacturing steel rope and submarine cable, demonstrating his commitment to pushing the boundaries of industrial possibilities. Two years later, his brothers, Thomas Bell and John Bell, joined him to build a major ironworks at Port Clarence, Middlesbrough, equipped with colossal blast furnaces that were the largest in Britain at the time. These blast furnaces produced iron for bridges and steel rails, contributing to the expansion of the British Empire's railways and industries. Bell's involvement extended to the North Eastern Railway Company, where he served as a director and later as deputy chairman. Bell's commitment to innovation wasn't confined to the production of steel and iron and in 1859, he opened Britain's first factory for the manufacture of aluminium, a metal previously considered as precious as gold due to the challenges of its extraction. The plant, located in Washington, utilized the innovative Deville sodium process, making Bell a pioneer in the field. He emphasized the importance of producing pure aluminium, recognizing that even the slightest impurities could affect its properties. Throughout his career, Bell continuously explored new processes and improvements, such as the recycling of heat from escaping flue gases. In 1863, he exhibited thallium, a recently discovered element, at the British Association meeting in Newcastle. This thallium was obtained from the flue deposits at Washington, emphasizing his engagement in scientific and industrial research. One of Bell's notable achievements was overcoming the challenge of using the Cleveland ironstone for steelmaking, a task considered daunting due to the mineral’s high phosphorus content. Through large-scale experiments, he developed a basic steel process that yielded steel rails with minimal phosphorus content, further contributing to the development of the steel industry. Bell also played a key role in comparing the state of iron manufacturing in Britain with foreign competitors, particularly in France, Belgium, and Germany, underlining the importance of Britain's vast coal reserves and the role of labour costs in the industry's success. In 1882, Bell's exploration extended to drilling for salt at Port Clarence, a venture that led to the discovery of an exploitable salt bed. This salt resource would be significant for the production of soda. Sir Isaac Lowthian Bell's contributions extended to various sectors, from metallurgy to chemicals, and his legacy is still apparent in the industrial landscape of Britain.
