THE CHARMS OF NATURAL SCIENCE.

The Earl of Derby, in an address at the Edinburgh University, said:

"Of the gains derivable from natural science I do not trust myself to

speak; my personal knowledge is too limited, and the subject is too

vast. But so much as this I can say--that those who have in them a

real and deep love of scientific research, whatever their position in

other respects, are so far at least among the happiest of mankind....

No passion is so absorbing, no labor is so assuredly its own reward

(well that it is so, for other rewards are few); and they have the

satisfaction of knowing that, while satisfying one of the deepest

wants of their own natures, they are at the same time promoting in the

most effectual manner the interests of mankind. Scientific discovery

has this advantage over almost every other form of successful human

efforts, that its results are certain, that they are permanent, that

whatever benefits grow out of them are world-wide. Not many of us can

hope to extend the range of knowledge in however minute a degree; but

to know and to apply the knowledge that has been gained by others, to

have an intelligent appreciation of what is going on around us, is in

itself one of the highest and most enduring of pleasures."

THE VESUVIUS RAIL WAY.--The Italian Ministry of Public Works, in union

with the Ministry of Finance and the Prefecture of Naples, has issued

the concession for the construction of the Vesuvius Railway. The line

will run along that part of the mountain which has been proved, after

the experience of many years, to be the least exposed to the

eruptions. The work is to be commenced immediately, and it is believed

that it will come into use during the present year. A sufficient

number of carriages are being built to convey 600 persons during the

day. The line is to be constructed upon an iron bridge, built after a

patented system.
