sight is similar to the finest Dartford gunpowder. It lias 
been used limitedly in this country by M. Bessemer, in his 
steel process, and others. 
The Bev. W. N. Moles worth drew attention to the 
earthquake which occurred that morning. 
Mr. Dyeb, also, and other members, gave an account of 
the phenomenon as experienced by themselves. 
Mr. II. D. Dakbishire, referring to observations made last 
spring, mentioned the remarkable multiplicity of coins 
current in Gibraltar, where silver money of many countries 
appears to circulate freely at ascertained values, and copper 
money in still greater varieties, to he used indiscriminately, 
subject only to a rude valuation according to size and 
weight. 
In remarkable contrast with the British system, under 
which nearly the whole copper coinage has been recalled and 
replaced within the last five years, and a gold or silver coin 
fifty years old would scarcely pass, Mr. Darbishire noticed 
the fact that the current money of Spain, as observed in 
several of the cities of Andalusia, Granada, and Valencia 
at this day, includes gold from the middle and silver from 
the earliest years of the eighteenth century, and copper from 
(at least) the year 1G01 . 
Referring to the copper currency, he mentioned the intro- 
duction, about 1848, of new pieces to represent decimal parts 
of the Real, and the ineffectual character of the measure 
owing to the small quantity of these new coins put into 
circulation. Practically they are suppressed amidst copper 
money of two centuries and a half.
