1066; "Oeuillade" is another name for the red-wine grape Cinsaut or Cinsault, that is widely planted in France. Cinsaut grapes can withstand very hot weather and are highly productive, creating wines that are light in body and neutral in flavor. Because of their high acidity and low tannins, Cinsaut wines are usually balanced with a blend of grenache and/or carignin (in Languedoc-Roussillon and surrounding areas). In the southern rhône where its yield is strictly controlled (a limited volume per acre), Cinsaut produces wines that are more deeply colored, concentrated, and flavorful.

- Oust is a odor eliminator the container of which has a quite phallic shape. And there's that phallic "U" again (See p.130), conjoined with "ball" which the Oxford English Dictionary defines as "5. Any rounded protuberant part of the body." It is thought that "ball" is derived from the Indo-European word bhel, meaning to blow, swell; with derivatives referring to various round objects and to the notion of tumescent masculinity. Derivatives include boulevard, boulder, phallus, balloon, ballot, and fool.  So Ewball Oust comfortably plays into The Sexual Angle in AtD, where sexual names proliferate.

753; Oxus, or Amu Darya, one of the great rivers of Central Asia. Prior to the meeting of the commissions appointed for the determination of the Russo-Afghan boundary in 1885, no very accurate geographical knowledge of the upper Oxus regions existed, and the course of the river itself was but roughly mapped. From Lake Victoria (Sor-Kul) in the Pamirs, which was originally reckoned as the true source of the river, to Khamiab, on the edge of the Andkhui district of Afghan Turkestan, for a distance of about 680 m., the Oxus forms the boundary between Afghanistan and Russia. For another 550 m. below Khamiab it follows an open and sluggish course till it is lost in the Sea of Aral, being spanned at Charjui, 150 m. below Khamiab, by the wooden bridge which carries the Russian railway from Mer y to Samarkand. 1911 Encyclopedia Brittanica
