Abstract
Model for the rectangular lid of 7 x 11 cm with 2 notches on the lower edge, which facilitate the rotation of the wheels; 2 holes for the rivets and two windows in which the solution of the problem raised with the 2 wheels will be read. On the front of this cover the name of the "Fertility Calendar" is printed and the names of the months of the year are divided into 3 groups (months of 28 days, 30 and 31), each of whose groups is framed between arrows that indicate those of the month of February the outermost thirds of the windows, those of the group of months of 30 days the average thirds, and those of the 31 of the inmates. On the back side of the cover are printed 2 semicircles with 31 divisions for the days of the month, from 1 to 31, being the squares for the 1 the most external, and those of the 31 the most internal.
