He then desctribes the "tremulous" motion of the seconds hand. What is a "verge watch"? Is it connected to the tremulous motion (which makes it difficult to read H4 to the nearest second)? When he implies it's not a chronometer, is he speaking of some fairly specific contemporary definition of a chronometer, c.1891? -FER --~--~---------~--~----~------------~-------~--~----~ Navigation List archive: www.fer3.com/arc To post, email NavList@fer3.com To , email NavList-@fer3.com -~----------~----~----~----~------~----~------~--~---
