S.--First coinage, 1794; none issued 1798, 1799, 1801, 1806 to
1828, inclusive. The coinage of half-dimes was discontinued in 1873 by
Act of Congress.

THREE-CENT PIECES (SILVER).--First coinage, 1851; and then the dates
follow in succession until 1873, when the coinage of them was
discontinued.

COPPER CENTS.

COPPER CENTS.--First coinage, 1793, none issued 1815; they then follow
to 1857, when the coinage was changed to nickel. The nickel cent of
1856 was only a pattern, which continued during this year up to 1864,
inclusive. The bronze cent was introduced in this year. In 1865 the
nickel cent was discontinued, and up to date the bronze cents are
issued.

HALF-CENTS.--First coinage, 1793; none issued 1798, 1799, 1801, 1812 to
1824, inclusive; 1827, 1837, 1838, 1839; in 1857 the issue of
half-cents was discontinued.

In 1864 the two-cent piece in bronze was introduced, and discontinued
in 1873, by Act of Congress.

In 1865 the three-cent nickel piece was first issued.

In 1866 the five-cent piece was first issued; a very few were struck in
1865 as pattern. In 1883 the die was changed to that of the current
issue with liberty head. Although upwards of five million coins of the
1883 nickels without the words "cents" were issued, they will in the
course of a few years command a premium. At present they are still
quite common.

LOISETTE'S SYSTEM OF MEMORY.

So much has been said about Loisette's memory system, the art has been
so widely advertised, and so carefully guarded from all the profane who
do not send five or many dollars to the professor, that a few pages
showing how every man may be his own Loisette, may be both interesting
and valuable.

In the first place, the system is a good one, and well worth the labor
of mastering, and if the directions are implicitly followed there can
be no doubt that the memory will be greatly strengthened and improved,
and that mnemonic feats, otherwise impossible, may be easily performed.
Loisette, however, is not an inventor, but an introducer. He stands in
the same relation to Dr. Pick that the retail dealer holds to the
manufacturer; the one produced the article; the other brings it to the
public. Even this statement is not quite fair to Loisette, for he has
brought much practical common sense to bear upon Pick's system, and in
preparing the new art of mnemonics for the market, in many ways he has
made it his own.

If each man would reflect upon the method
