respective charges may require during the present summer and coming

a moderate number of narcotics and sedatives, and an abundant supply
of tonics, astringents, aromatics and demulcents, while the list of
anodynes, emetics and cathartics remains in a comparative degree

HON. GEORGE W. RANDOLPH:

_Dear Sir_,--At the risk of seeming tedious, permit me to say that
my impression that you were mistaken last night in your recollection
of the extent to which Louis Napoleon used railroads in transporting
his army into Sardinia is this morning confirmed by a gentleman who
is a most experienced and well-informed railroad officer, and is
also the most devoted student of geography and military history,
with the most accurate and extraordinary memory for every detail,
however minute, of battles and all other military operations that I
have ever met with. He is positive in his recollection that not less
than 100,000 and probably more, of that army were gradually
concentrated at Toulon and sent thence by sea to Genoa, and the rest

confines of France and Italy, whence they were transferred, partly
on foot and partly on a double-track railroad, into Sardinia. The
capacity of a double-track railroad, adequately equipped like the
European railroads, may be moderately computed at five times that of
a single-track road like those of the Confederate States. For the
sudden and rapid movement of a vanguard of an army, to hold in check
an enemy till reinforced, or of a rear guard to cover a retreat, or
of any other portion of an army which must move suddenly and
rapidly, and for the transportation of ordnance, ammunition,
commissary and other military supplies, railroads are available and

attained, they can advantageously carry more troops according to the
amount of the other transportation required, the distance, their
force, and equipment, etc. But to rely on them as a me
