The SAO/NASA ADS site has several scanned articles on chronometer rating. http://adsabs.harvard.edu/abstract_service.html The search page looks complicated, but you only need to enter a couple fields near the top. Leave everything else alone. • Publication Date (near the top, below Authors). Dates here are inclusive. For example, to search the 1850s, use 01 1850 to 12 1859. • Title Words. Enter "chronometer". The search engine's synonym function is enabled by default, so "chronometer" also finds "chronometers". Then click any of the Send Query buttons. A page will appear with links to the matching articles. With a low speed connection, the 3-pane window for viewing GIF documents is often slow because the number of thumbnail images far exceeds the number of pages in the article. Sometimes it seems the entire publication is being loaded! The solution is to click Next Page, then click the place where image of that next page will appear. That takes you to a page without thumbnails. The reason for clicking Next Page before you even read the first one is a bug in the site. If you omit this step, it says the requested page doesn't exist. But it's there -- you just have to go back to it from the second page. There's an odd sentence in Toynbee's November 1853 article in the Monthly Notices of the Royal Astronomical Society, "On Rating Chronometers by Lunars". http://articles.adsabs.harvard.edu/cgi-bin/nph-iarticle_query?journal=MNRAS&year=%3f%3f%3f%3f&volume=..14&letter=.&db_key=PRE&page_ind=19&plate_select=NO&data_type=GIF&type=SCREEN_GIF&classic=YES&high=4899d32e1929742 "Late in 1850 I took the command of another ship, my chief officer during this voyage, on account of the delicate state of his health, was prevented from taking lunars." I knew lunars were demanding, but I didn't know they were that hard! -- --~--~---------~--~----~------------~-------~--~----~ Navigation List archive: www.fer3.com/arc To post, email NavList@fer3.com To , email NavList-@fer3.com -~----------~----~----~----~------~----~------~--~---
