Dear Bill, Thank you very much for your response. I have, though, already seen this WEB site earlier and obtained a copy of the 1929/30 publication in the New Zealand Journal of Science and Technology, which up to now has been one of my prime sources on the history of the IDL. I recently came across another useful source for the history of the IDL prior to 1900 in: H.M. Wallis & A.H. Robinson, Cartographic Innovations: An International Handbook of Mapping Terms to 1900 (Map Collector Publications, Londen, 1982), art. 'Date Line'. =============================================================== * Robert H. van Gent * Tel/Fax: 00-31-30-2720269 * * Zaagmolenkade 50 * E-mail: r.h.vangent@astro.uu.nl * * 3515 AE Utrecht * Home page (under construction): * * The Netherlands * http://www.fys.ruu.nl/~vgent/ * ================================================================
