A full description of the model's presentation to the British Association for the Advancement of Science is published in the Report for their Meeting held in Birmingham during September 1849.

This model is an accurate representation of a part of the Moon's surface as it appears through a Newtonian telescope of seven feet focus and nine-inch aperture, under a magnifying power of about 250.

It is about thirty miles in diameter and stands at the end of a lofty range of mountains not far from the centre of the Moon's disc.

A hilly district, rising into two or three lofty peaks, runs upwards from Eratosthenes, connecting it with what appears to have been an ancient crater now filled up.

Touching the edge of this crater and descending from it towards the right, may be seen a long line of minute volcanic cups, which are nearly the smallest objects visible with the instrument by which the observations were made.
