| Description | Birt outlines his reasons for the continuation of the Kew Observatory and discusses his considerations.
Discussion on the electrical observations, Birt includes remarks from the Registrar General Mr [James] Glaisher, regarding the indications of the electrical instruments at Kew and Greenwich. Birt argues that the reasons for the different amounts of electricity between the Kew Observatory and the Royal Observatory, Greenwich should be investigated.
Birt discusses the self-registering instruments, and includes remarks made in the [Kew?] Committee report 1846.
Discussion on the meteorological observations. Birt acknowledges the complete nature of meteorological observations at Greenwich being made at two hourly intervals. The results however apply only to the locality of Greenwich, and each locality possesses its own type or barometric curve. |
