To those who are mothers, every part of this small book is especially commended. Upon the knowledge and skill and right action of those who have the care of children and of the household, it will depend that the right thing shall be done in such emergencies as are liable to occur. You must necessarily care for your children, both to guard them from sickness and to relieve their ailments. You must know the symptoms, at least, how to observe the symptoms of diseases; and you may be called upon, in the absence of the physician, to act as midwife. Be especially careful to learn the instructions in regard to emergencies, because upon your knowledge and prompt action the lives of your dear ones may depend. TO THE PROFESSIONAL NURSE. This work is written for you, and to you is especially commended the modicum of medical knowledge herein contained. It is better for you to learn well what you read than it is to read very extensively. You will find sufficient in this small volume to demand your time and study for months, and even for years, in connection with your nursing. It is not expected that you will learn all the formulæ and prescriptions given. These are inserted partly that you may learn to read prescriptions in the various forms in which they are written, and partly that you may occasionally use one, after consulting with your physician. Sometimes you may copy one of them accurately and use it at the drug store, consulting only with the apothecary. But it will be of importance to you to obtain as much medical knowledge as is herein contained, though it is not designed to make you physicians. Do not act the part of a doctor until you understand every thing pertaining to Anatomy and Physiology, and the nature and properties of every medicine employed in the cure of disease. Of all sciences the medical should embrace the widest domain of knowledge, because ignorance here is fatal. But ignorance and thoughtlessness, and want of skill and adaptation, may be fatal in your particular province. The physician will generally tell you that the recovery of his patient depends as much upon faithfulness and skill and care on your part as upon his own medicines. Seek always to aid him, never to supercede him. If you learn midwifery, it should be with the design of co-operating with the doctor, and assisting him. You should be so educated that the physician will feel willing to leave a case of tedious labor in your care, instead of waiting at the bedside of the patient one or two days, and neglecting his other patients. Your educated service will be appreciated at such times by the doctor, as well as by the patient and her friends. You will do the duties of nursing well, and take upon yourself that part of the practice of a physician which he does not desire, and which you can do equally well. Your part will be an important one, and second only to that of the physician.
