Opaline budgerigar mutation

The Opaline budgerigar mutation is one of 30 mutations affecting the colour or appearance of budgerigars. It is the underlying mutation of the Opaline variety; when combined with the Yellowface II and Clearwing mutations the Rainbow variety is produced. The Opaline mutation is characterised by several features which are invariably present, although many show variations in the intensity of their expression; the most obvious effect is on the striations which extend from the top of the head down the neck to between the wings in the non-Opaline. In the Opaline these striations are much reduced in intensity, being absent in many individuals in small birds of yellow feather; the cap of the Opaline extends further back over the top of the head merging into an area the same colour as the body which continues down the back of the head to form a'V' shape between the wings. The intensity of the striations in this area is variable, but in the original mutations the Australian, the'V' was clear. In the non-Opaline the wings show dark grey or black markings over a yellow or white ground, but in the Opaline the ends of the barbs of the wing coverts assume the same colour as the body, rather than the ground colour.

This suffusion of body colour in the wings produces the opalescent effect which gave the mutation its name. The area of black pigmentation in each feather is reduced and in the original specimens the wing butts were devoid of black pigment, resulting in a clear area called the'thumb-print'; these thumb-prints appear to be associated with a clear'V', but are now seen less since the Budgerigar Standard calls for normal wing markings in the Opaline. The flight feathers of the budgerigar consist of 10 secondaries; these are dark grey with a clear central band across every feather from the 2nd primary to the 8th secondary. These clear areas are not visible in the folded wing, but form a prominent continuous band running right along the wing when it is stretched out, it is visible from beneath. In the Opaline this clear band is much broader. Only the distal half of the flight feather is dark, with the clear zone extending from the midpoint to the shaft; because it is broader it is visible in the primaries of the folded wing of the Opaline, just beneath the secondaries and primary wing coverts, as a small clear patch.

A similar effect occurs in all the wing feathers, most noticeably in the primary and secondary wing coverts, in the six tail feathers, which carry a similar clear band on feathers 2 to 6 in the non-Opaline. The first tail feather of the Opaline carries a rather blotchy clear area of somewhat variable extent, the suffusion of body colour present to a small degree in the non-Opaline is intensified in the Opaline. Most Opalines show a brighter body colour than the corresponding non-Opaline in nest feather and in the rump area; this is due to a reduction in the melanin content of the barbules of the contour feathers. The final characteristic of the Opaline is the colour of the down feathers of the young nestling; these are white instead of the usual grey, this allows Opalines to be identified at a early age. In 1933 A Brown of Kilmarnock, bred what was described as a'pied' Cobalt hen from a normal Skyblue cock and Mauve hen; the parents came from a strain kept locally which had never produced anything unusual, Mr Brown bred no more than the one mutant though the same pair bred many Cobalts in both 1933 and 1935.

Towards the end of 1933 Mr and Mrs Ashby of nearby Ayr purchased this'pied' Cobalt, which they described as being "exceptionally large with a fine head and most excellent spots", although both parents were quite mediocre. The mutant's peculiarities were that the head and nape were pure white with slight markings in places and nearly all the flight feathers and secondaries, were edged with cobalt in place of white, making the bird a'Cobalt-wing'; the mutant was not a pied of any of the present-day types, but an Opaline, although the variety was not to be known by that name until a few years later. In 1934 the Ashby's paired the mutant hen to a quality Light Green split blue cock and Skyblues, Light Greens and a Dark Green of a normal appearance were bred. In 1935 one of the Skyblue cocks was mated back to the mutant hen, the first nest produced two Opaline Cobalt cocks and an Opaline Skyblue hen; the Opaline mutation had been fixed. Early in 1936 circumstances forced the Ashby's to dispose of all their Opalines, which at that time were known as'Marbled', the entire stock, with the exception of two pairs which went to Andy Wilson of Glasgow, went to Walter Higham of Blackburn, under the care of his aviary manager, Len Hillas.

From these two studs came the vast majority of British Opalines, most of them carrying the wide head and large spots which first caught the attention of the Ashby's. In Australia around 1933, Mr S E Terrill discovered a mutant budgerigar, a Light Green hen in nest feather, among thousands of wild birds caught by trappers and sent to Adelaide market, he bought her, described her special features as "... complete absence of barring on the back of the neck and mantle and its replacement by the body colour... the mask being extended back, covering the top of the head... the bars on the wing coverts reduced in number and intensity, their yellow margins being enlarged and nuch suffused in green." Mr Terrill, who lived near Adelaide, paired the hen to a Blue Silver (the Aus

Curtiss-Reid Rambler

The Reid Rambler known under the Curtiss-Reid brand after Reid was purchased by Curtiss, was a biplane trainer/sport aircraft built in Canada in the early 1930s and used in small numbers as a trainer aircraft by the Royal Canadian Air Force. In 1928, Wilfrid T. Reid set up his own company in Montreal after working as an engineer for Canadian Vickers, his first design was a light aircraft, intended to exploit a Canadian government programme to support the development of flying clubs. The Reid Rambler was intended to be a training aircraft; the Rambler was a conventional sesquiplane design with wings braced with Warren trusses and which could be folded backwards for transport or storage. The fuselage was of fabric-covered steel tube construction and the pilot and a single passenger sat in tandem, open cockpits; the prototype was first flown at the Cartierville Airport on 23 September 1928 by Martin Berlyn. The test flight was nearly a disaster because the ailerons seized, leaving Berlyn with a dangerous approach and landing.

A modification of the aileron control linkage rectified the problem. The Rambler continued to be developed, in 1931, an improved version, the Rambler III, was flown with the more powerful Gipsy III engine. John C. Webster flew the MK III prototype in the British King's Cup Race that year. In December 1928, the Curtiss Aeroplane & Motor Company purchased the Reid Aircraft Company and renamed it The Curtiss-Reid Aircraft Company; the new firm established a production line. A number of alterations were made to the production series including replacing the original ailerons with Frise-style ailerons, introducing an unbalanced rudder along with changes to the engine cowling, exhaust system and tailskid, adding a head rest. Although it was intended principally for civilian use, the Royal Canadian Air Force evaluated the aircraft as a basic training aircraft. Although the RCAF employed many other ab-initio aircraft including the ubiquitous de Havilland Moth, senior military staff elected to purchase a small number of the Ramblers.

Curtiss-Reid Ramblers enjoyed a productive and lengthy career both in civilian and military use lasting well into the Second World War era. Data from:Canadian aircraft since 1909 Rambler Mk.

Teiji Takagi

Teiji Takagi was a Japanese mathematician, best known for proving the Takagi existence theorem in class field theory. The Blancmange curve, the graph of a nowhere-differentiable but uniformly continuous function, is called the Takagi curve after his work on it, he was born in the rural area of the Gifu Japan. He began learning mathematics in middle school, reading texts in English since none were available in Japanese. After attending a high school for gifted students, he went on to the University of Tokyo, at that time the only university in Japan. There he learned mathematics from such European classic texts as Salmon's Algebra and Weber's Lehrbuch der Algebra. Aided by Hilbert, he studied at Göttingen. Aside from his work in algebraic number theory he wrote a great number of Japanese textbooks on mathematics and geometry. During World War I, he was isolated from European mathematicians and developed his existence theorem in class field theory, building on the work of Heinrich Weber; as an Invited Speaker, he presented a synopsis of this research in a talk Sur quelques théoremes généraux de la théorie des nombres algébriques at the International Congress of Mathematicians in Strasbourg in 1920.

There he found little recognition of the value of his research, since algebraic number theory was studied in Germany and German mathematicians were excluded from the Congress. Takagi published his theory in the same year in the journal of the University of Tokyo. However, the significance of Takagi's work was first recognized by Emil Artin in 1922, was again pointed out by Carl Ludwig Siegel, at the same time by Helmut Hasse, who lectured in Kiel in 1923 on class field theory and presented Takagi's work in a lecture at the meeting of the DMV in 1925 in Danzig and in his Klassenkörperbericht in the 1926 annual report of the DMV. Takagi was internationally recognized as one of the world's leading number theorists. In 1932 he was vice-president of the International Congress of Mathematicians in Zurich and in 1936 was a member of the selection committee for the first Fields Medal, he was instrumental during World War II in the development of Japanese encryption systems.

Alexander Brown Portus was an Australian engineer and politician. Portus was born at Black Creek, near Morpeth, the son of a mill owner John Portus and wife Elizabeth, he was educated at a local school under a Mr. Carmichael, travelled to Europe at 21 for the 1855 Paris Exhibition visiting Canada and the United States. Upon his return, he worked as an engineer alongside his brother at Raymond Terrace, he was a director of the Maitland and Morpeth Railway Company and the Hunter River New Steam Navigation Company. In May 1861, he was one of Charles Cowper's 21 appointments to the New South Wales Legislative Council, however did not take his seat in the council, he was appointed to the dredge section of the Department of Public Works in 1865 under Edward Orpen Moriarty. He was assigned to Newcastle as master and engineer of the dredge Hunter, in 1873 assumed command of the new dredge Newcastle, he was promoted to head the section as superintending engineer for dredges in 1886, at which time he moved to Sydney.

He was credited with having been responsible for designing many of the state's dredges and upgrading the colony's dredging capacity. He retired from the public service in September 1904, he died at his home in Sydney in 1905 and was buried at Morpeth
