I have been induced to bring this subject before the meeting as astronomers
have already begun to talk of preparing means and adopting situations for
making unremitted observations on the next transit of Venus over the Sun's
disc, in 1874 and 1882. It is essential to remark that the transits will take
place in the month of December, and at that time the earth's South Pole will
be turned towards the sun, and those regions of the earth included between
the South Pole, and the southern limit of illumination will be carried by
rotation, opposite to the direction of all the northern parts of the earth.
Only two transits of this planet over the sun have occurred since Dr. Halley
invoked the attention of astronomers to these rare astronomical events, viz.,
in 1751 and 1769. The transit of 1769 was most favorable, and afforded an
opportunity which can only occur once in a lifetime

In 1855 its name changed to Royal Society of Tasmania for Horticulture, Botany, and the Advancement of Science. In 1911 the name was shortened to Royal Society of Tasmania.|
