Such an arrangement is a balance between an exaggerated emphasis on the metre — which would cause the verse to be sing-songy — and the need to provide some repeated rhythmic guide for skilled recitation.

The opening movement was normally in duple metre and in a major key ; the slow movement in earlier examples was usually quite short, and could be in a contrasting key ; the concluding movement was dance-like, most often with rhythms of the gigue or minuet, and returned to the key of the opening section.

Although they are sometimes considered uncommon, they are probably often overlooked because of their small size: densities of over 90, 000 individuals per square metre have been measured.

The centres of their large webs are often just under 1 metre above the ground, so they are too low for anything much larger than a rabbit to walk under.

By contrast, the verse preserved from the skalds consists mostly of poems in praise of kings and incidental verse preserved in the sagas, often done up in the elaborate metre, and the ballad-like forms that form most of the corpus of the Poetic Edda.

Wallace successfully quelled the Bombers ' scoring power and defeated the team which had won the previous 20 games by playing 14 of the 18 men on the field in the defensive zone for the entirety of the game, and often with all 18 players taking up positions in the 50 metre arc.

These are usually 1 metre wide, and are bounded by thinner solid white lines, and often without a rumble strip.

25 metre pistol ( formerly called sport pistol ) is essentially the women's equivalent of this event, the only difference being the smaller rimfire caliber handguns used ( often the same models only chambered for the smaller caliber ).

The unit newton metre is properly denoted N · m or N m. This avoids ambiguity with mN, millinewtons.

The metre is denoted by the syllable count of each line, i. e. 8. 6. 8. 6 or 86. 86, depending on style, or by its shorthand abbreviation " CM ".

Caving was pioneered by Édouard-Alfred Martel ( 1859 – 1938 ) who first achieved the descent and exploration of the Gouffre de Padirac, France as early as 1889 and the first complete descent of a 110 metre wet vertical shaft at Gaping Gill, in Yorkshire, England in 1895.

The CGS system has been largely supplanted by the MKS system, based on metre, kilogram, and second.

Starting in the 1880s, and more significantly by the mid-20th century, CGS was gradually superseded internationally for scientific purposes by the MKS ( metre – kilogram – second ) system, which in turn developed into the modern SI standard.

* De triumphis ecclesiae, a Latin epic in elegiac metre, written c. 1250 by Johannes de Garlandia, an English grammarian who taught at the universities of Toulouse and Paris.

Just as work began at the Champ de Mars, the " Committee of Three Hundred " ( one member for each metre of the tower's height ) was formed, led by Charles Garnier and including some of the most important figures of the French arts establishment, including Adolphe Bouguereau, Guy de Maupassant, Charles Gounod and Jules Massenet: a petition was sent to Charles Alphand, the Minister of Works, and was published by Le Temps.

A metre was originally defined as the 40-millionth part of the length of a meridian ( the target was not quite reached in actual implementation, so that is off by 0. 02 % in the current definitions ).

; Open access navigation: This will be available without charge for use by anyone with appropriate mass-market equipment ; simple timing, and positioning down to 1 metre.

It is characteristic of early literature that the evolution of the thought, or the grammatical form of the sentence, is guided by the structure of the verse ; and the correspondence which consequently obtains between the rhythm and the syntax — the thought being given out in lengths, as it were, and these again divided by tolerably uniform pauses — produces a swift flowing movement such as is rarely found when periods are constructed without direct reference to the metre.

The metre can also be described by initials ; L. M.

The metre has been imitated in English ; the most important examples are by Alfred Tennyson and Swinburne and Robert Frost, cf.

Although it was later determined that the first prototype metre bar was short by a fifth of a millimetre because of miscalculation of the flattening of the Earth, this length became the standard.

In 1893, the standard metre was first measured with an interferometer by Albert A. Michelson, the inventor of the device and an advocate of using some particular wavelength of light as a standard of length.

Although the metre is now defined as the path length travelled by light in a given time, the practical laboratory length measurements in metres are determined by counting the number of wavelengths of laser light of one of the standard types that fit into the length, and converting the selected unit of wavelength to metres.

* 1791 March 30The French National Assembly accepts the proposal by the French Academy of Sciences that the new definition for the metre be equal to one ten-millionth of the length of the Earth's meridian along a quadrant through Paris, that is the distance from the equator to the north pole.
