French Wine – Booklet on Instruments for the Examination of Red Wine Colour – J. Dujardin -1902

An interesting 24-page booklet by J. Dujardin published in Paris in 1902.

The French title “L’Examen de intensite colorante des Vin Rouges par le Vino-Colorimetre Salleron” it goes on to say the methods can be applied to Spanish wines, liqueurs etc.

The booklet describes the scientific approach to assessing wine quality and colour on a scale designed by J Salleron. At the completion is effectively a price list and description of the various accoutrements necessary to satisfy this important science

Cased Anemometer By Baird & Tatlock

A pretty good example of a low speed air meter by top maker Baird & Tatlock. Likely designed for and used in the coal mining industry.

In its original felt lined leather case with attachment screwed to case lid as required. The only blemish is a pressure crack on the face and some paint loss on the blade casing.

The instrument still works well which is somewhat unusual as discard was one way these instruments left their place of work.

The instrument comes with a sliding braking system which protects the delicate gearing. Overall a good example now hard to find

The Malay Archipelago -The Land of the Orang-Utan and the Bird of Paradise, with Studies of Man and Nature – Alfred Russel Wallace

Wallace’s great book dedicated to Charles Darwin. Beautifully written. An early fourth edition published by Macmillan in 1872. Nevertheless scarce and sought after.

Octavo, 653 pages. Re-cased at some time with the spine and front laid down; with the desired Orang-utan gilt device retained on front and similarly bird of paradise retained on front. Some marks near front but generally in good condition. Priced to condition for a scarce desirable item.

Wallace collected over 125,000 specimens identifying thousands of new species during this expedition. This book represents the backbone of his discoveries (The Wallace line) that supports the “Origin of Species”. Well illustrated with maps and engravings

Wallace – Monumental work – vies with “Origin”

Folding Georgian Guinea Scales c1805

A good set of early Guinea Scales with contemporary instructions label. Likely by Stephen Houghton who took over from Anthony Wilkinson at Ormskirk, Lancashire. Wilkinson had died in 1804.

The end pin is bit tight which means the set need to be pulled gently to open.

Self-erecting and known generally as the Lancashire Gold Balance. The brass beam is rectangular in section and has a hinged “turn and swing” overweight which counter poises the beam for the guinea or half-guinea. This set has an uncommon variation with the weight having two components, clearly designed for additional weighing standards.

A small rectangular sliding weight on the load arm registers in graduations to show discrepancies in of under-weight coins.

The collapsing mechanism makes the whole entirely portal in the gentleman’s trouser.

The Forces of Nature – A Popular Introduction to the Study of Physical Phenomena – Amedee Guillemin – Translated by Mrs Norman Lockyer – Edited and with Additions from J Norman Lockyer – 1873

Despite being a “Popular” edition, this substantial book is very scarce indeed, possibly because it would have been very expensive in the day. No expense was spared in producing the illustrations.

This copy housed in a rather flash full leather binding, albeit showing some sign of wear with leather scuffs etc. The binding reflects the provenance which was as a prize at the Hereford Cathedral College in England. At the front is the most elegant manuscript prize inscription in Latin, of course.

Large royal octavo, 679 pages, with over 150 illustrations, some in colour from chromolithographs.

A most enterprising book on physics which not only still holds some educational interest today but for anyone interested in the history of the development of the physical sciences then its hard to pass by. Starts with Gravity, Weight, and Universal Attraction … Falling Bodies … the Laws … Newton etc. then Hydrostatics, weights in liquids … Archimedes, Boyle etc Barometers, Pumps Mariotte’s Law. Sound, reflection, velocity, refraction, vibrations, strings, waves etc. Sources of light, photometry, reflection, refraction, colours, spectrum. Radiation, phosphorescence, nature of light, polarization. Heat, calorimetry, a species of motion. Magnets, electrical attraction and repulsion, electrical machines. Leyden Jars, induction, electrical lighting (remember 1873) and finally Atmospheric Meteors.

We have already indicated that there is so much to like about this book. At Voyager we have always had a fascination regarding electro induction devices such as the Wimshurst machine. Here we have several woodcuts of some of the more superior “electrical machines” of the day … just superb.

A super gift for anyone interested in early fundamental physics and or the history of the science.

The Theory of Atomic Collisions – Mott and Massey (Professor Westfold’s Copy) – First edition 1933

A first UK edition, published at Oxford by the Clarendon Press in 1933. The standard full text of the period.

Large octavo, 282 pages. Original black cloth covered boards with gilt titles to spine. Dust jacket rather drab and aged but unusually present. The signature of K. C. Westfold and dated October 44 on the front free end paper.

Comprehensive high level text starting with The Wave Equation then Scattering – by a Centre Force, by a Coulomb Field. The Spin of the Electron. Collisions. Inhomogenous Differential Equations. General Theory of Atomic Collisions. Born’s Approximation. Scattering of Slow Electrons. Inelastic Collisions. Electrons and Molecules. Massive Particles. Transition Probability. Relativistic Treatment of the Two Body Problem …. Nuclear Problems.

The excellent index is a read itself of the who was who in higher mathematics including a notable relative of Voyager!

K.C. Westfold (1921-2001) a brilliant Australian mathematical brain was Professor of Applied Mathematic at Monash and at various time Dean of Science, Professor of astronomy and Vice Chancellor of the University. He was an Archibald Prize sitter.

Cornerstone book of the period in this supreme area of mathematical physics – nice relevant previous ownership.
