Note.—The exact positions of the observations in the same localities are not identical in the case of all observers, which accounts for some of the apparent discrepancies.
[433]The Dankaba observation is of somewhat doubtful accuracy.
[434]The Tanut longitude depends on only one stellar observation for L.M.T.
[435]Jean’s longitude for T’in Shaman, which is the site of the French post and therefore also of the rest-house where the Cortier observation was taken, differs so materially from the latter that it cannot be accepted. It is described (like the position he gives for Iferuan) as “d’après F. Foureau,” but I can find no record in the account of the proceedings of the Foureau-Lamy Mission to justify this statement.
