At six months of age the child begins to lisp, and at twelve months it is usually able to utter distinct and intelligible sounds of one or two syllables. The development of the senses and of the mind proceeds gradually. The sense of hearing is more active and further advanced than that of sight. Sounds are appreciated sooner than light or bright colored objects. The next sense which is developed is perhaps that of taste; then follow smell and touch. THE FOOD OF INFANTS AND CHILDREN. The diet of children is frequently improper either in regard to quantity, quality, or variety. In 1867, a committee, of which Professor Austin Flint, Jr., was chairman, was appointed in New York city to revise the 'Dietary Table of the Children's Nurseries on Randall's Island.' In the report rendered, attention was forcibly called to the fact that in childhood 'the demands of the system for nourishment are in excess of the waste, the extra quantity being required for growth and development. If the proper quantity and variety of food be not provided, full development cannot take place, and the children grow up, if they survive, into young men and women, incapable of the ordinary amount of labor, and liable to diseases of various kinds. This is frequently illustrated in the higher walks of life, particularly in females; for many suffer through life from improper diet in boarding schools, due to false and artificial notions of delicacy or refinement. After a certain period of improper and deficient diet in children, the appetite becomes permanently impaired, and the system is rendered incapable of appropriating the amount of matter necessary to proper development and growth.' Charlotte Bronté has drawn, in _Jane Eyre_, a graphic and physiologically true picture of the effects upon young girls of long-continued insufficiency of food. Let mothers bear in mind that proper food cannot be too abundantly eaten by children, and that the greatest danger to which they are exposed arises from defective nutrition. We would again urge the value of a large amount of _milk_ in the dietary of young people. The disorders of the bowels, which are not uncommon in infancy and childhood, are due to errors in diet by which improper food is supplied, and not to an excess of simple and proper nourishment. We have already given some directions for the preparation of infants' food in treating of 'bringing-up by hand.' In addition to the various substitutes for the mother's milk there mentioned, we wish to note that known as _Liebig's soup_. This great chemist thus describes the method of making it:
