ADVERTIs.e.m.e.nTS.

_The value of the_ SCIENTIFIC AMERICAN _as an advertising medium cannot be over-estimated. Its circulation is ten times greater than that of any similar journal now published. It goes into all the States and Territories, and is read in all the princ.i.p.al libraries and reading-rooms of the world. We invite the attention of those who wish to make their business known to the annexed rates. A business man wants something more than to see his advertis.e.m.e.nt in a printed newspaper. He wants circulation. If it is worth 25 cents per line to advertise in a paper of three thousand circulation, it is worth $2.50 per line to advertise in one of thirty thousand._

RATES OF ADVERTISING.

BACK PAGE - - - - 1.00 A LINE, INSIDE PAGE - - - 75 CENTS A LINE,

_for each insertion_.

_Engravings may head advertis.e.m.e.nts at the same rate per line, by measurement, as the letter-press_.
