Under the old law, where, as stated above, a copyright notice later than the actual copyright was disallowed as claiming protection beyond the copyright term, a later decision, in 1888, in Callaghan v. Myers, held, that where a copyright notice gave the year 1866, while the true date was 1867, there was no harm done to the public, because a year of the copyright, which really ended in 1895 instead of 1894, was given to the public, whereas in the previous case an additional year was claimed. Doubt was thrown upon this decision by Judge Wallace in Schumacher v. Wogram, also in 1888. In Snow V. Mast in 1895, the substitution for 1894 of the abbreviated '94, and in Stern v.

It is further provided (sec. 19): "That the notice
