the moon showed the shadow of the earth as being that of a globe. 
This proof, and that of Foucault’s pendulum, were shown and 
explained by lantern slides. 
A few interesting remarks were made regarding the relations 
between tbe earth and the moon, in size, gravitation, etc. The 
longitudinal and latitudinal lines and degrees were explained. 
The lecture was brought to an end by a few words in favor of the 
astronomer’s day and time-piece, which were not divided into two 
parts of twelve hours each, but formed one continuous day of 
twenty-four hours.
