New digital collection: documents from 1874 transit of Venus
You may be interested in the newly released collection of digitised
papers at Cambridge Digital Library, added to the successful Board of
Longitude Collection that was released in 2013.
The Transit of Venus collection includes a selection of papers and
photographs from the Royal Greenwich Observatory archive, including
journals kept by Captain George Lyon Tupman as he oversaw training at
Greenwich from 1872, led the expedition to Honolulu in 1874 and returned
to the Observatory to process the mass of observations until 1880.
There are also images and lists of the instruments and stores taken, and
the Kailua sub-station journal kept by George Forbes.
In addition to this we have had permission to photograph private papers
from the Tupman family, including an album and private journal kept by
Tupman and two wonderful volumes of caricature drawings by one of the
Honolulu observers, Lieutenant E.J.W. Noble.
