An Inquiry into the Animism and Folk-lore of the Guiana Indians by Walter Roth – First Edition 1915

Those that know about Walter Roth and his incredible work and publications relating to the Northern Queensland aboriginals may be surprised with this similarly important anthropological work on the native Indians of Guiana [Guyana].

Without raking too much up, Roth was more or less expelled for his Queensland work as, in his obsession for detail, he was deemed to overstep the mark more than once. However, he was quickly given a plum job in British Guiana.

Roth was employed in British Guiana as stipendiary magistrate, medical magistrate and district commissioner and was responsible for producing the Aboriginal Protection Order of 1910. Continuing his anthropological work, he made three extensive field expeditions which formed the basis of this book and various related papers. On his retirement he stayed there and became the curator of the Georgetown Museum and government archivist. He died there in 1933.

Walter Roth had a fascinating life and produced some special work that without him would have been lost to the World.

Vacuum Pump with Dome – Griffin and Tatlock c 1930 – Super Example

A very good working example of a vacuum hand pump, complete with glass dome from notable maker Griffin and Tatlock [a design by John Griffin]

Nice oak handle, the brass pump body retains its original lacquer, valve moves freely and pumps seals nicely. The glass dome with bell top handle is ground for contact with the pump base plate [in operation this would be grease/ vaseline sealed. There is a small chip to the inside rim but not impinging on the “sealability” of the instrument.

Carries the Griffin and Tatlock branding plaque. We can date this to around 1930 as John Griffin and sons merged with the distinguished Scottish form Baird and Tatlock circa 1925.

Dimensions approx. – 40 cm long 30 cm high and 18 cm wide. Not really suitable for overseas and will require a postage supplement dependent on buyer location.

Rare complete and working a genuine sucker.

Antique Microscope Slide – Exhibition Standard – Arranged Diatoms with Spicules of Syncyota Holothuriale [Sea Cucumber] – W. A Firth – c1890.

A circle arrangement of numerous diatom types along with spicules from the cucumber – these spicules forming part of the sea cucumber’s skeletal structure.

William Allott Firth [1853-1923] was a professional mounter specialising is diatoms. Born in Barnsley, England he moved as a child with his family to Belfast where he remained for the rest of his life. His slides are regarded as of the highest quality, and this is an unusual example. His name label is supported by his characteristic handwriting which never varied.

The slide is difficult to precisely date partly because of the consistency of Firth’s handwriting noted above. The labelling arrangement is identical with Bracegirdle’s example Plat 17/K but no date is given. Bracegirdle does show a slide dated 1877 but we think this one is later – probably circa 1890. The pricing noted is a later reseller.

Good condition given age albeit crack across cover slip not affecting the view.

Complex arrangement of diatom types and spicules by expert Firth.

Fuller’s Spiral Slide Rule [Calculator] – Manufacturer W.F. Stanley, London

Invented by George Fuller, Professor of Engineering at Queens’s College Belfast, patented in 1878.

The rule consists of a logarithmic scale of numbers spiral wound in the form of a helix; the scale is 500 inches [circa 42 feet] in length having 7,250 divisions. This rule is therefore equivalent to a straight slide rule twice that length or c 84 feet. If you understand the principle – it’s the [lack of] length of a slide rule that inhibits accuracy. It can be held in one hand while performing calculations or fixed on the removable brass holder if more convenient. The mahogany box is true to the instrument and has felt covered fittings to protect it in transit. The original instruction booklet is still with the instrument.

The manufacturer was W.H. Stanley at one time the biggest instrument maker in the World. Stanley a Fellow of all the right Societies was an architect and had near 100 patents to his name.

This instrument is one of the last manufactured, which probably accounts for its pristine condition. We can date it to 1965 for two reasons. First, all instruments were numbered at the bottom of the B cursor, and this one is serial number 13111 and below that stamped 65 for 1965. Secondly, there is a magnificent paper published by the esteemed Oughtred Society [Look it up] which gives excellent background information on the instrument and provides a graph of the serial numbers and dates of a good sample from No 1 in 1884 to number 13688 in 1973 – so you can see that ours is placed right in the twilight zone.

We find it interesting that only 14,000 instruments were ever made over a period of 90 years. After a slowish start and an end tail-off the graph of units made is pretty steady with a bit of a jolt during WWI and WWII. Your guess is right it was killed pretty dead by Hewlett Packard.

We haven’t gone into full details of how the instrument is constructed and functions, but we do have information in our Research Section, and you can always look up the aforementioned “Oughtred” reference – best information going – forget Wiki.

In terms of size the box is 46 cm x 12 cm x 11 cm. The rule is 43 cm long 9 cm in diameter.. Total weight around 2 kgs.

A postage supplement may be required dependent on location of buyer.
