slow starvation, that even the substance of the kidneys and of the brain are often found softened and otherwise altered, though it might not unreasonably have been supposed that these organs lay quite beyond the reach of any disorder of digestion.
No doubt all these grievous results do not always follow; and sometimes children exceptionally strong manage to take and digest enough even of unsuitable food to maintain their health, and may as they grow up, and the changes take place in the system which fit it for a varied diet, even become robust. In the majority of instances, however, hand-fed infants, and those especially who have been brought up chiefly on farinaceous food, are less strong than others, and are more apt to develop any latent tendency to hereditary disease, such as scrofula or consumption, than members of the same family who have been brought up at the breast.
Enough has already been said to satisfy all but those who do not wish to be convinced, how incumbent it is on every mother to try to suckle her child. But though it is most desirable that for the first six months of their existence children should derive their support entirely from their mother, and that until they are a year or at least nine months old their mother's milk should form the chief part of their food, yet many circumstances may occur to render the full adoption of this plan impracticable. In some women the supply of milk, although at first abundant, yet in the course of a few weeks undergoes so considerable a diminution as to become altogether insufficient for the child's support; while in other cases, although its quantity continues undiminished, yet from some defect in its quality it does not furnish the infant with proper nutriment. Cases of the former kind are not unusual in young, tolerably healthy, but not robust women; while instances of the latter are met with chiefly among those who have given birth to several children, whose health is bad, or among the poor, who have been enfeebled by hard living or hard work. The children in the former case thrive well enough for the first six weeks or two months, but then, obtaining the milk in too small a quantity to meet the demands of their rapid growth, they pine and fret, they lose both flesh and strength, and, unless the food given to supply their wants be judiciously selected, their stomach and bowels become disordered, and nutrition, instead of being aided, is more seriously impaired. In the case of the mother whose milk disagrees with the child from some defect in its quality, the signs are in general more pronounced. Either the infant vomits more than that small quantity which a babe who has sucked greedily or overmuch often rejects immediately on leaving the breast, or it is purged, or it seems never satisfied, does not gain flesh, does not thrive, cries much and is not happy. In these cases, too, the mother's supply of milk, though abundant at first, diminishes in a few weeks; she feels exhausted, and suffers from back-ache, or from pain in the breasts each time after the child's sucking; while, further, her general weakness leaves her no alternative but to wean the child.
Knowing the attempt to rear her child entirely at the breast to be vain, the mother may in such cases be tempted to bring it up by hand from the very first. But how short soever the period may be during which the mother may be able to suckle her child, it is very desirable that she should nurse it during that period, and also that her milk should then constitute its only food. For the first four or five days after the infant's birth the milk possesses peculiar qualities, and not merely abounds in fatty and saccharine matter, but presents its casein or curd in a form in which it is specially easy of digestion. These peculiarities indeed become less marked within a week or two; but not only is it of moment that the infant should at any rate make its start in life with every advantage, but the mother who nurses her little one even for a month avoids thereby almost half the risks which follow her confinement. For the indolent, among the wealthy, a numerous class who have but to form a wish in order to have it gratified, a wet-nurse for the baby suggests itself at once to the mother as a ready means of saving herself trouble, and of shirking responsibility. This course, to which love of pleasure and personal vanity tend alike to prompt her, often finds, in spite of all opposing reasons, the approval of the nurse, to whom it saves trouble, and the too ready acquiescence of the doctor in a course which pleases his patient. But many circumstances besides those moral considerations, which ought never to be forgotten before the determination is formed to employ a wet-nurse, may put this expedient out of the question, and it becomes therefore of importance to learn what is the best course for a mother to adopt who is either wholly unable to suckle her child, or who can do so only for a very short time.
It is obvious that the more nearly the substitute approaches to the character of the mother's milk, the greater will be the prospect of the attempt to rear the child upon it proving successful. There is no argument needed to prove that the milk of some animal more closely resembles the mother's milk, and is more likely to prove a useful substitute for it than any kind of farinaceous substance. The milk of all animals, however, differs in many important respects from human milk, and differs too very widely in different animals. Thus, the milk of the cow and that of the ewe contain nearly double the quantity of curd, and that of the goat more than twice the quantity of butter, and it is only in the milk of the ass that the solid constituents are arranged in the same order as in man. On this account, therefore, asses' milk is regarded, and with propriety, as the best substitute for the child's natural food. Unfortunately, however, expense is very frequently a bar to its employment, and compels the use of the less easily digested cows' milk. But though the cost may be a valid objection to the permanent employment of asses' milk, it is yet very desirable when a young infant cannot have the breast, that it should be supplied with asses' milk for the first four or five weeks, until the first dangers of the experiment of bringing it up by hand have been surmounted. The deficiency of asses' milk in butter may be corrected by the addition of about a twentieth part of cream, and its disposition to act on the bowels may be lessened by heating it to boiling point, not over the fire but in a vessel of hot water; and still more effectually by the addition to it of a fourth part of lime-water or of a teaspoonful of the solution of saccharated carbonate of lime to two ounces or four tablespoonfuls of the milk.
When cows' milk is given, it must be borne in mind that it contains nearly twice as much curd, and about an eighth less sugar, than human milk. It is therefore necessary that it should be given in a diluted state and slightly sweetened. The dilution must vary according to the infant's age; at first the milk may be mixed with an equal quantity of water, but as the child grows older the proportion of water may be reduced to one-third. Mere dilution with water, however, leaves the proportion of curd unaltered, and it is precisely the curd which the infant is unable to digest. Instead, therefore, of diluting the milk simply with water, it is often better to add one part of whey to about two parts of milk, which, according to the child's age, may or may not be previously diluted8.
Attention must be paid to the temperature of the food when given to the infant, which ought to be as nearly as possible the same as that of the mother's milk, namely from 90° to 95° Fahrenheit, and in all cases in which care is needed a thermometer should be employed in order to insure the food being given at the same temperature. Human milk is alkaline, and even if kept for a considerable time it shows little tendency to become sour. The milk of animals when in perfect health likewise presents an alkaline reaction, and that of cows when at grass forms no exception to this rule. Milk even very slightly acid is certain to disagree with an infant; it is therefore always worth while the moment that a hand-fed infant seems ailing to ascertain this point. If alkaline, the milk will deepen the blue colour of litmus paper, which is to be had of any chemist; if acid, it will discharge the colour and turn it red. It is, perhaps, as well to add that, as the oxygen in the atmosphere tends to redden litmus paper, it should not be left exposed to the air, but should always be kept in a glass-stoppered bottle.
The milk of the cow is very liable to alteration from comparatively slight causes, and particularly from changes in the animal's diet; while even in the most favourable circumstances if the animal is shut up in a city and stall-fed, all the solid constituents of its milk suffer a remarkable diminution; while the secretion further has a great tendency to become acid, or to undergo even more serious deterioration. Mere acidity of the milk can be counteracted for the moment by the addition of lime-water, or by stirring up with it a small quantity of prepared chalk, which may be allowed to subside to the bottom of the vessel; or if it should happen, though indeed that is rarely the case in these circumstances, that the child is constipated, carbonate of magnesia may be substituted for the chalk or lime-water. If these simple proceedings are not sufficient to restore the infant's health, it will be wise
The directions given by the distinguished chemist, Dr. Frankland, to whom I am indebted for the suggestion, are as follows: 'One-third of a pint of new milk is allowed to stand until the cream has settled; the latter is removed, and to the blue milk thus obtained about a square inch of rennet is to be added, and the milk vessel placed in warm water.' (I may add that the artificial rennet sold by most chemists may be substituted for the other.) 'In about five minutes the rennet, which may again be repeatedly used, being removed, the whey is carefully poured off, and immediately heated to boiling to prevent its becoming sour. A further quantity of curd separates, and must be removed by straining through calico. In one quarter of a pint of this hot whey is to be dissolved three-eighths of an ounce of milk sugar, and this solution, along with the cream removed from the one-third of a pint of milk, must be added to half a pint of new milk. This will constitute the food for an infant of from five to eight months old for twelve hours; or, more correctly speaking, it will be one-half of the quantity required for twenty-four hours. It is absolutely necessary that a fresh quantity should be prepared every twelve hours; and it is scarcely necessary to add that the strictest cleanliness in all the vessels used is indispensable.'
