Mr. Dickinson read a Paper, “ On the Occultation of the 
Planet Jupiter by the Moon, May 24, 1860.” 
This phenomenon, as it occurs a considerable time before 
sun-set, will not be visible to the unassisted eye ; such 
persons, however, as possess good telescopes will have an 
opportunity of observing it, if the state of the atmosphere will 
permit; and for the purpose of enabling them to compare 
their observations with the computed times, the following 
results of a calculation are submitted to the members of this 
Society : —
