[time-nuts] Re: Ship's clocks @ The Royal Society

Hi Poul:

Do you have any information about the tripod platform John Emeaton designed for the clock?
https://en.wikipedia.org/wiki/John_Smeaton
It's my understanding that the clock would need to be regulated as to it's rate because of local gravity and set to the 
correct time prior to making Venus/Sun transit measurements.  All that done by astronomy I'm guessing this would be made 
more fool proof if sidereal time was used.

PS Part of the design of the Western Union clocks is a parking space for the pendulum to be used when shipping.  It's 
too bad that people today don't know about it and in some cases destroy clocks.
