ABSTRACT
The education of the tactile and the thermic senses go together, since the warm bath, and heat in general, render the tactile sense more acute. The education of stereognostic sense leads to the recognition of objects through feeling, that is, through the simultaneous help of the tactile and muscular senses. The first didactic material used by us is made up of the bricks and cubes of Froebel. In many of the authors' lessons on the colours, they make use of pieces of brightly-coloured stuffs, and of balls covered with wool of different colours. Experiments in colour-memory may be made by showing the child a tint, allowing him to look at it as long as he will, and then asking him to go to a distant table upon which all of the colours are arranged and to select from among them the tint similar to the one at which he has looked.
