Visual and Tactile Perception of Alphabetical Signs.

Reading and Writing.—The didactic material for this purpose consists of:—A set of script letters, the vowels cut from sandpaper and mounted on blue cards, and the consonants of black emery cloth mounted on white cards. By passing the index and second finger over these letters, following the direction in which they are written, the child obtains the tactile perception of the form, and at the same time is taught the sound of each letter.

Composition of Words.—For word-building the letters are of the same size and shape as the sandpaper letters on card, but are cut out of cardboard and unmounted, the vowels being made of blue and the consonants of pink cara.

Four sets of these cardboard letters are contained in two flat boxes, each letter having its special compartment.
