required in consequence is carefully detailed. The cardinal purposes of a sanitary teacher are to preserve the health of the child, to restore it when lost and to prevent disease. While giving full scope to the fulfilment of these purposes, the author admits, with reserve, the necessity of indicating the means of curing some of the ailments and chief diseases incident to childhood. He enjoins the mother to send for a physician as soon as the case requires medical aid, and he gives the additional and often-needed advice to abide strictly by the directions of her medical adviser. There are times, however, when the suddenness and violence of the attack and the inability to procure timely professional assistance throw the mother on her own resources, and it is under these circumstances that the author teaches her how to act and what prescriptions to give, but not without many cautions on his part. It must still be continually borne in mind that everything can be done in the way of prevention, and much in the way of cure, by a timely and judicious use of the ordinary hygienic means applied for the growth and preservation of the child, viz.: air, water, food, clothing, exercise of the body and nurture of the affections. The medicine-chest ought never to form part of the furniture of the nursery. Meddlesome medicine is bad, and that medicine is always meddlesome when it is applied without actual necessity, clearly indicated by a competent judge. The mother will find this judge in the author of the present volume.
