I would think it would be quite easy to get you some logarithmic tables. One option, of course, is to copy (double-sided) the important tables from one of your copies of Norie's and use the copy instead of the original. You could do this at your local library or at a nearby office supply store or Kinko's. Since you haven't done this already, there must be something I don't understand about what you want to do. There are several sources of logarithmic tables available online. I understand how difficult it is to get the good stuff online if you are using a dialup connection. Are any of thes what you want? Do you need help getting PDFs of any of these? Of course, if you decide to print, say, 72 pages or so of any of these on your home printer, you will probably not enjoy the experience. Renee "Four-place logarithmic tables: together with a Table of Natural Sines, Cosines, Tangents" by Webster Wells, 1900, for example http://books.google.com/books?id=AhQAAAAAYAAJ&dq=logarithmic+tables -- download PDF 1.1 Mb. 23 pages Here's one that might be even better: have a look at the text version of the table of contents: (http://ia340929.us.archive.org/1/items/logarithmictable00jonerich/logarithm ictable00jonerich_djvu.txt) 72 pages 5.2 Mb pdf (http://ia340929.us.archive.org/1/items/logarithmictable00jonerich/logarithm ictable00jonerich_bw.pdf) I have also found, online, an 1807 edition of The new practical navigator (42 Mb -- I think you'd need someone to mail you a CD for this one!) http://www.archive.org/details/newpracticalnavi00moorrich And here's one called Tables of the moon; constructed for the use of the American Ephemeris and Nautical Almanac (http://www.archive.org/details/tablesofmooncons00peiruoft). Again, you'd need help getting a copy of this one. It's from 1865, and has the following tables. TABLES la., 16., and Ic. are Tables of Astronomical Dates in mean solar days reckoned from the beginning of the Julian Period, from which the date of any event can be reduced to days and decimals of a day when it is originally given in the usual form with reference to the Christian Era. Tables Ila. and 116. contain the values of the mean longitude, the negative of the longitude of the node, and all the arguments for the mean Washington noon of every thousandth day from 2300000 to 2500000. Tables Ilia, and III6. contain the motions of the mean longitude, and of the lon- gitude of the node for every interval of days and fractions of a day less than 1000 days, and the first ten multiples of all the periods. Table IV. contains the constants by which the mean longitude, and the longitude of the node, and the various arguments, can be reduced, from the interval from 2400000 to 2500000 days to any previous time after the commencement of the Julian Period. Tables Va. and V6. contain the corrections of the various arguments for HANSEN'S term of long period in the action of Venus. Tables VI. to LXXXII. inclusive contain the different equations of the moon's lon- gitude. Tables VI". to XXXVII". inclusive contain the second differences for a quarter of a day of the moon's longitude. Tables VI. IV - to XVI. IT inclusive contain the fourth differences for a quarter of a day of the moon's longitude. Tables LXXXIII. to CIX. inclusive contain the terms of the moon's latitude. Tables CX. to CXXVII. inclusive contain the terms of the moon's horizontal par- allax. Table CXXVIII. contains the table for the moon's semidiameter. ________________________________ From: NavList@fer3.com [mailto:NavList@fer3.com] On Behalf Of halboth halboth-at-juno.com |Renee Mattie on NavList| Sent: Tuesday, August 14, 2007 12:14 PM To: ..................... Subject: [NavList 3101] Navigation tables Hi all, I have been, for somewhat over 60 years now, been using a 1904 Edition of Norie's Tables for Lunar Distance calculations and general navigation purposes. This edition includes all necessary tables for clearing the distance, including six place logarithmic tables to seconds of arc for small angles, as well as the usual trig functions, haversine functions, and all necessary altitude corrections for the Moon and Planets, both for true and apparent - features which are not included in later editions. My problem is that I would like to replace these tables, which are becoming dilapidated by age and wear associated usage, with something equally comprehensive and handy, including possibly on disc. I have several copies of Norie's Epitome, which include most of these tables, but do not wish to expose these pubs to the wear and tear of frequent look-ups, as they have been completely refurbished and rebound. Does anyone out there have any suggestions. I have just about exhausted my internet capabilities, which are limited to dial up at present, but which otherwise have produced no concrete results as respects logarithmic tables of any type. It does seem rather strange, to me at least, that nobody has put tables such as this on disk or that no reprints have been produced. I am also somewhat leery of the older available downloads, as the tables included therein frequently contained rather subtle errors which were not readily apparent at the time of printing. Thanks in advance for any interest and help.
