Mr. Jones’s death occurred very suddenly on the 21st of 
December last, and was so unexpected that at the Meeting 
of the Society, which took place in the succeeding week, a 
communication by a non-member, on a new invention for 
propelling ships, was to have been made through him and 
explained by him to the Society. 
Mr. Caw, one of the other deceased members, acted as 
Librarian to the Society during three years, viz., from 1853 
to 1856. 
Among the Honorary Members of the Society one death 
has taken place during the past year, viz., that of Dean 
Peacock, the eminent Mathematician.
