A little ramble through 19th century astronomy - The Inter Mercurial Planet in 1877

 Nature January 25th 1877

The Inter Mercurial Planet

In M. Leverrier’s last communication to the Paris Academy on the planet assumed to exist within the orbit of Mercury, it was mentioned that, with the elements adopted, or very similar ones, a solar conjunction would occur on March 22, and a transit over the sun’s disc was possible though uncertain.

A close examination of the disc is therefore recommended on March 22 and 23, and there is reason to believe that observers in widely differing longitudes are prepared to undertake it.

If no transit should occur, eight or nine years may elapse before one is possible at the spring node.
