"No fact in medicine is better established than that which proves the hereditary transmission from parents to children of a constitutional liability to pulmonary disease, and especially to consumption; yet no condition is less attended to in forming matrimonial engagements. The children of scrofulous and consumptive parents are generally precocious, and their minds being early matured, they engage early in the business of life, and often enter the married state before their bodily frame has had time to consolidate. For a few years every thing seems to go on prosperously, and a numerous family gathers around them. All at once, however, even while youth remains, their physical powers begin to give way, and they drop prematurely into the grave, exhausted by consumption, and leaving children behind them, destined, in all probability, either to be cut off as they approach maturity, or to run through the same delusive but fatal career as that of the parents from whom they derived their existence."[FN#5] There is scarcely an individual who reads these facts, to whom memory will not furnish some sad and mournful example of their truth; though they perhaps may have hitherto been in ignorance of the exciting cause. [FN#5] Combe's Principles of Physiology applied to the Preservation of Health, etc. It is, however, with the mother as a nurse that I have now to do, and I would earnestly advise every one of a consumptive or strumous habit (and if there is any doubt upon this point, the opinion of a medical adviser will at once decide it) never to suckle her offspring; her constitution renders her unfit for the task. And, however painful it may be to her mind at every confinement to debar herself this delightful duty, she must recollect that it will be far better for her own health, and infinitely more so for that of the child, that she should not even attempt it; that her own health would be injured, and her infant's, sooner or later, destroyed by it. The infant of a consumptive parent, however, must not be brought up by hand. It must have a young, healthy, and vigorous wet-nurse; and in selecting a woman for this important duty very great care must be observed.[FN#6] The child should be nursed until it is twelve or fifteen months old. In some cases it will be right to continue it until the first set of teeth have appeared, when it will be desirable that a fresh wet-nurse should be obtained for the last six months.[FN#7] If the child is partially fed during the latter months (from necessity or any other cause), the food should be of the lightest quality, and constitute but a small proportion of its nutriment.
