HITHER'fO no value of the solar parallax has been derived from the observations of the tmnsit of Venus made at the American stations in 1874. In the volume of obsel'vations recently issued, Part the FiJ'st, General JJj:scuss£on of Results, [u'e given most of the data which are necessary for the derivation of the solar pamllax f!'Om (1) the photographs of the tram;it. (2) the optic observations of the transit. We shall concern ourselves only with the photo· graphic results: these are presented… 
The 1874 Transit of Venus and the Popularisation of Astronomy in the USA as Reflected in the New York Times
Given uncertainty surrounding the true value of the astronomical unit following the 1761 and 1769 transits of Venus the next transit, in 1874, offered hope for a substantial refinement in the value

Through the presence of two 1874 American transit of Venus stations, Tasmania played a key role in determining a value for the astronomical unit. But what makes these two stations even more important

The 1874 transit of Venus: New Zealand's first foray into international astronomy
The nineteenth century transits of Venus provided astronomers with the opportunity to use these rare events to calculate the solar parallax, and New Zealand played a vital role. Apart from activities
