It is reported that the function of the clock at Bidston performed a service similar to that at Cambridge Observatory, ie. it was kept to accurate Greenwich time for the purpose of time distribution. It was placed into a room adjacent to the observing rooms and at some stage was fitted with electrical contacts for the same purpose. Reference: http://www.inbeat.org/wp-content/uploa...)

Each could hold one hundred chronometers which would be observed at temperatures between 50º to 85ºF throughout the year. The glazed lids of the boxes allowed observations to be made without requiring their removal. Temperatures would be changed weekly on a Saturday by 10º or 15ºF to show...)
