question: What was was first seen and discussed there at a meeting on March 11, 1802?
context: After the surrender, a dispute arose over the fate of the French archaeological and scientific discoveries in Egypt, including the artefacts, biological specimens, notes, plans, and drawings collected by the members of the commission. Menou refused to hand them over, claiming that they belonged to the Institute. British General John Hely-Hutchinson refused to relieve the city until Menou gave in. Scholars Edward Daniel Clarke and William Richard Hamilton, newly arrived from England, agreed to examine the collections in Alexandria and claimed to have found many artefacts that the French had not revealed. In a letter home, Clarke said that "we found much more in their possession than was represented or imagined".Hutchinson claimed that all materials were property of the British Crown, but French scholar Étienne Geoffroy Saint-Hilaire told Clarke and Hamilton that the French would rather burn all their discoveries than turn them over, referring ominously to the destruction of the Library of Alexandria. Clarke and Hamilton pleaded the French scholars' case to Hutchinson, who finally agreed that items such as natural history specimens would be the scholars' private property. Menou quickly claimed the stone, too, as his private property. Hutchinson was equally aware of the stone's unique value and rejected Menou's claim. Eventually an agreement was reached, and the transfer of the objects was incorporated into the Capitulation of Alexandria signed by representatives of the British, French, and Ottoman forces.
  It is not clear exactly how the stone was transferred into British hands, as contemporary accounts differ. Colonel Tomkyns Hilgrove Turner was to escort it to England, but he claimed later that he had personally seized it from Menou and carried it away on a gun-carriage. In a much more detailed account, Edward Daniel Clarke stated that a French "officer and member of the Institute" had taken him, his student John Cripps, and Hamilton secretly into the back streets behind Menou's residence and revealed the stone hidden under protective carpets among Menou's baggage. According to Clarke, their informant feared that the stone might be stolen if French soldiers saw it. Hutchinson was informed at once, and the stone was taken away—possibly by Turner and his gun-carriage.Turner brought the stone to England aboard the captured French frigate HMS Egyptienne, landing in Portsmouth in February 1802. His orders were to present it and the other antiquities to King George III. The King, represented by War Secretary Lord Hobart, directed that it should be placed in the British Museum. According to Turner's narrative, he and Hobart agreed that the stone should be presented to scholars at the Society of Antiquaries of London, of which Turner was a member, before its final deposit in the museum. It was first seen and discussed there at a meeting on March 11, 1802.
