Frank, I am impressed that by 1884 the manufacturing world had advanced to the point where "Excellent chronometers can be purchased brand new for 25 to 30 pounds..." in England. However, I am not sure that this is indicative of the situation in 1850 which was, as you recall, the watershed year in which you claim that it became more economic to buy a second sextant than to buy a good sextant. Certainly, in the United States, manufacturing did not get into gear until after the Civil War. (Indeed, at the start of the Civil War the number of steam engines (both stationary and for use in transport) in the entire United States did not exceed 5000.) The centre of the world's chronometer industry at this time - and for many decades to come - was Prescott in Lancashire here in England. The vast majority of chronometer makers bought the parts from Prescott manufacturers and built them up into chronometers with their own names on them. This is true for chronometer makers in the US as well and I think it is true to say that by 1850 no chronometer had been completely made by an American clock maker 'from the plates up'. Indeed, this is generally true right up until WWII when Hamilton started to fill the urgent requirement for chronometers for the US navy. Perhaps more indicative of the price of chronometers at the time of interest is a letter dated June 19, 1863 from Captain J. M. Gillis, U.S.N. Superintendent of the US Naval Observatory to Rear Admiral Davis, Chief of the Bureau of Navigation. Regarding the acquisition of chronometers he wrote, "In the judgement of of Messrs. Negus and Company, Messrs. Eggert and Sons and Messrs. Bliss and Company, the only makers of chronometers in New York, $250 will be a reasonable compensation for chronometers of the standard exacted for naval service."

Whitney) Geoffrey At 03:40 16/07/2009, you wrote: >Geoffrey, I've got a few more bits of data on prices of chronometers >versus sextants. > >First, there's Lecky c.1884: >"[one can get longitude...] first by the chronometer, and secondly >by Lunars.
