Group A:—A line 12mm. long, starting from the junction of the upper left curve and the inner, white, frame-line will extend to the end of the horizontal stroke of the first "E" of "THREE". (Var. 11 to 18.)
Group B:—A line 12mm. long, starting from the junction of the upper left curve and the inner, white, frame-line will extend to a point just beyond the end of the horizontal stroke of the first "E" of "THREE". (Var. 19 to 27.)
Class II.
A line 14mm. long, starting from the junction of the upper left curve and the inner, white, frame-line, will extend to a point just outside of the final "E" of "THREE". (Var. 28 to 30.)
Variety 11:—The top stroke of "N," if extended, would bisect the vertical stroke of "T". "RE" very wide at top. "T" and "E" about an equal distance from curves. Lower left curve well rounded. "EN" near at top. "N" broad.
Variety 12:—The small horizontal line of "N," if extended, would cut the vertical downstroke of "T." All the centre crossbars of "Es" touch the horizontal upper stroke. "N" of "CENTS" is narrow; is the lowest letter, and has a heavy middle line. "T" and "E" are close to the curves, which are short. "TS" close and on level.
There are often two dots in the central oval, one near the throat and the other opposite the third loop above "C". Compare variety 11 for "NT," also variety 21.
