I am thankful books like these are scanned and freely available. Yes the manual step to properly scan fold out drawings is omitted in many cases. The scanning is automated and the manual scan to expensive. A greater problem is the availability of individual drawings like these, having been cut out of books, stolen and sold on ebay. Then they are lost for good.
Fred, Thanks for the link to Pluche. The section on dialing was interesting as an example of the importance of the topic for educated people back then. I also looed at some of the other volumes of the series "Spectacle de la Nature" In Vol IV there is a great section on the armillary sphere. The drawing on page 219 was poorly scanned but I found it elsewhere. This is an excellent copper plate drawing that you will see again. Here is a link to the book. https://books.google.ca/books?id=E-I4AAAAMAAJ&printsec=frontcover&source=gbs_ge_summary_r&cad=0#v=onepage&q&f=false and to the drawing: http://www.atlascoelestis.com/pluche%20strumenti.htm Regards, Roger Bailey From: Fred Sawyer Sent: Monday, February 29, 2016 2:30 PM To: Putowsky Cc: Sundial List Subject: Re: Horary machine Stanislav - that's exactly right. It's extremely frustrating to find a scan that gives the text but does not reproduce the graphic. Fred On Mon, Feb 29, 2016 at 10:32 AM, Putowsky <[email protected]> wrote: Hello Fred. Thank you very much for your very accurate answer. It is a shame that the guys from Google Books doesn't know how to digitize books. They mutilate allways the most important pages for a gnomonist, the images. It only cost a little bit more of time to digitize also the prints!. At least the books digitized by Microsoft have text and also the prints. The guys from Google didn't realized that a book digitized in the way they do is worth almost for nothing? May be somebody can tell them to do a well done digitized copy? Stanislav Putowsky.
