Can education do much for the improvement of hearing? Everyday experience answers in the affirmative. There is an exercise which cannot be too highly commended to parents, which consists in inducing in play their children, even those very young, to detect from as far as they can faint and fading sounds. It is a game which amuses them much, and it is a pleasing sight to see the rivalry of several young children, each of whom with head bent forward, is earnestly trying to distinguish a receding sound longer than its fellows. A little ingenuity will readily devise amusing and useful plays with this object in view. The training of the remaining special senses is of comparatively minor importance to that of those we have been considering, and need not detain us. We will only remind the reader of the wonderful adroitness and delicacy of touch possessed by the blind as an example of what this sense is capable of when educated. HOME MANAGEMENT OF SOME COMMON DISEASES OF CHILDREN. CROUP. Although this disease is said to be more severe in Europe than in our own country, and more frequent in our northern than in our southern States, most American mothers, in all parts of the country, know and dread its alarming and often fatal attacks. It is a disease of childhood, but not of early infancy, being rarely met with under the first or after the tenth year of life. Children who have once had this affection are very liable to another attack upon exposure to any of the causes which excite it. It has been noticed also that croup runs in certain families, and not unfrequently, children of a ruddy complexion and of a fleshy and apparently vigorous appearance are those most subject to it. Among the _causes of croup_, which should be specially guarded against by mothers of croupy children, are checking of the perspiration, sudden alterations in the dress, change of climate, and even in some cases a residence at the sea-side. Croup also often follows measles, and at times is epidemic.
