Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

Southern African birdfinder - where to find over 1400 bird species from South Africa to Zambia, is the essential companion to all local bird field guides.

It fills a gap in the market for a guide to the region's top birding spots and to finding southern Africa and Madagascar's most desirable birds. After an introduction to birding in the region, the authors outline and describe 39 key bird routes and more than 330 birding sites across South Africa, Namibia, Botswana, Zimbabwe, Madagascar and the little-documented but increasingly popular areas of Angola, Mozambique, Zambia and Malawi.

Sites include practical details of access, best times to visit, habitat diversity and the birds that occur in it, and general natural history; the more important sites feature a detailed map.

Before his untimely death from typhoid, William Spottiswoode (1825-83) had served as president of the London Mathematical Society, the British Association, and the Royal Society. In addition to publishing widely in mathematics and the experimental physical sciences, he restored the fortunes of his family printing firm, Eyre and Spottiswoode, the Queen's printers. An enthusiast for the popularisation of science, he lectured to large audiences at the Royal Institution, the South Kensington College of Science, and at British Association meetings. He also gave scientific talks at the school set up for the employees of his family firm. This illustrated 1874 work is based on these talks, and provides an introduction to 'this beautiful branch of optics'. Spottiswoode covers methods of polarisation, and the contemporary theory accounting for these effects. He describes various experiments, and explains how polarisation causes patterns and colours to appear in light.

In a manner completely acceptable to the professional film maker, yet thoroughly understandable and of great value to the amateur cinematographer, Spottiswoode presents the essential, unwritten lore of documentary film making. The book deals first with the ideas for a documentary film, and shows how they are embodied ina script. It explains how the production unit is assembled, and goes on to describe the mechanism of the camera, the primary instrument of film making. The chapters which follow discuss the important creative process of editing, optical printing, the film library, and negative cutting. A special section deals with the physics of sound, the technical methods of recording it, and the creative uses to which sound can be put in film. A long chapter describes current color processes and 16-mm. techniques. Successive chapters take the reader through all the steps of the production from script to screen and give him clues to what practices he should adopt and what he should avoid. A number of simplified procedures in animation are described here for the first time. The book ends with an annotated bibliography of technical works on film, and an extensive, 1000-word glossary of film terms defined with the needs of the amateur in mind.
