	Joseph-Nicolas Delisle
		Delisle is chiefly remembered as the author of a method for observing the transits of Venus and Mercury by instants of contacts.
		As a preliminary to the transit of Mercury in 1743, which he personally observed, he issued a map of the world showing the varied circumstances of its occurrence.

		The Delisle family was at the heart of this geographic illusion.
		Guillaume Delisle, the royal geographer and a member of the Academy of Sciences, imagined the Western Sea on a hand-drawn globe produced in 1699.
		In the absence of conclusive discoveries, the idea of a Western Sea was raised again by Joseph-Nicolas Delisle (1688-1768) and Philippe Buache (1700-1773), both eminent geographers and, respectively, the brother and son-in-law of Guillaume Delisle.

	Charles Messier
		Delisle himself introduced him into elementary astronomy and convinced him of the usefulness of measuring exact positions of all observations -- without doubt one of the most important preliminaries for the success of his catalog.
		Delisle himself had calculated an apparent path where he expected comet Halley to appear, and Messier created a fine star chart of this path.
		Messier as loyal employee stated: "I was a loyal servant of M. Delisle, I lived with him in his house, and I conformed with his command." When Delisle finally announced the discovery on April 1, 1759, it was not believed by the other French astronomers (perhaps they took it as an April Fool's joke).

		After staying in Russia for 22 years, where he was the founder of the Petersburg Observatory, Delisle came back to France in the year 1747.
		During all these years, Delisle had enlarged the circle of his acquaintances, which has been very useful to launch the "avertissements" to recommand observations of some peculiar astronomical phenomena.

	DE L'ISLE, Guillaume (Site not responding. Last check: 2007-10-31)
		The Delisle (de L'Isle) family followed the Sansons as a major influence in the development of French cartography at the very beginning of the eighteenth century at a moment when Dutch publishers were finally losing their control of the map trade.
		Like Nicolas Sanson, Claude Delisle was a geographer and historian and had four sons, all of whom made their mark in the life of the time, but Guillaume was the most remarkable member of the family.
		Two of his brothers, Joseph Nicolas and Louis, spent many years in the service of Peter the Great in Russia where they organized a school of astronomy and carried out extensive surveys in areas hitherto hardly visited.

	Lalande biography
		While studying for his law degree he lodged at the Hotel de Cluny in Paris and it was there that the astronomer Joseph-Nicolas Delisle had his observatory.
		Lalande was fascinated by astronomy and, although he continued to study law, he also attended Delisle's astronomy lectures at the Collège Royale as well as Pierre Lemonnier's lectures on mathematical physics.
		In the year he took over as editor, Lalande was offered another prestigious position namely to follow his teacher Delisle as professor of astronomy at the Collège Royale.

		Delisle himself had calculated an apparent path where he expected comet Halley to appear, and Messier created a superb star chart of this path.
		Delisle however, distressed over Messier’s silent implications, would neither admit nor believe that he’d made a mistake, and so refused to announce Messier’s discovery.
		When Delisle finally announced the discovery on April 1st, 1759, it was scoffed at by the other French astronomers, as an April Fool's joke.

	Transits of Venus
		Halley hoped that with a measurements good to a couple of seconds, astronomers might determine the distance to Venus with an accuracy of one-fifth of one percent.
		In the years before the transit of 1761, the French astronomer Joseph Nicolas Delisle suggested a different approach to the problem.
		In addition, Delisle's technique requires that the absolute time of each event in the transit be recorded.

	Rare Old Maps and Sea Charts of Pacific Northwest and Alaska by Grace Galleries of Harpswell Maine
		The chart was drawn to show the explorations in the North Pacific in the early 1700's and includes the voyages of Vitus Bering in 1728 and 1741 to the Strait that bears his name and the southern coast of Alaska.
		Chart also depicts the tracks of Joseph Nicolas Delisle's voyage with Capt. Tchirkov in 1741 and De Frondat's voyage from China to California in 1709.
		(Note the chart is based upon the mss surveys of Joseph Nicolas Delisle (1688-1768) who studied with Cassini as an astronomer and cartographer, later working in Russia where he founded the Academy of Sciences at St. Petersburg before returning to Paris in 1747, after having made his epic voyage with Capt. Tchirkov in 1741.

		If the two observers know their exact positions on Earth, he argued, they only need to record the moment when the edge of Venus lines up with the edge of the Sun.

	Critical Cartography - Saul Albert
		In his commentary, Steven Brown spatialises Serres' metaphor of the passage more specifically, placing the 'Northwest Passage' in 'the twisting and convoluted coastlines that separate the great Atlantic and Pacific Oceans'.
		However, Serres' metaphor becomes more intriguing when his 'Northwest Passage' is related to the putative 'Northwest Passage' from the account of the French colonial explorer Admiral deFonte, that the early 18th Century 'theoretical geographers'; Guillaume and Joseph-Nicolas Delisle and Phillipe Buache hypothesized into their maps of the interior of North America.
		In order to explain the incomplete, sometimes conflicting data of topological survey, navigational charts, a composite of Cree maps and irregular reports from explorers, they deducted a series of rivers and an inland sea; the 'Mer de L'Ouest', and plotted deFonte's 'Northwest Passage' through this imagined topography.

	Transit of Venus - Nehru Centre
		Halley’s method consisted of measuring the time elapsed between the first and the last interior contact of Venus with the solar disk from at least two sites having a greatest possible difference in latitude.
		The French astronomer Joseph-Nicolas Delisle (1688-1768) proposed, in1722 another method related to the observation of a single phase of a transit, the first or last interior contact.
		This method increased the number of possible observing sites.

		Prior to the transit of Venus in 1761, Edmond Halley and Joseph-Nicolas Delisle developed methods of determining the distance between the Earth and the Sun using transit observations.
		The method required precise timings of the moment in time that the limb of the fl silhouette of Venus touched the limb of the Sun.
