Henley needle galvanometer used in receiving the first telegraphic message transmitted across the Atlantic Ocean, made by W T Henley, British, around 1858.

This galvanometer was installed at the Valentia (Ireland) end of the 1858 transatlantic cable, and in August received the first message transmitted from Newfoundland: 'Europe and America are united by telegraphy. Glory to God in the highest; on earth, peace and good will toward men'. However, as its design was based on ordinary telegraph practices, it was not sensitive enough to make a satisfactory receiver for long distances.
