4. "Mothers who, at the birth of their first child weigh less than fifty-five kilograms and are under twenty years of age, have children of inferior weight, who are less predisposed to normal growth" (Schafer).
Let us recall what we have said regarding the form and the scanty weight in the case of macrosceles; and also in regard to the age of procreation in its relation to stature.
5. "Women who toil at wearisome work up to the final hour give birth to children inferior in weight to those born of mothers who have given themselves up to rest and quiet for some time before the expected birth" (Pinard).
All these considerations which refer to normal individuals, represent a series of hygienic laws regarding maternity, which may be summed up as follows: excellence in procreation belongs to those mothers who have already attained the age at which the individual organism has completed its development, and before it has entered upon its involutive period; the mother must herself have a normal weight; the pregnancies must be separated by long intervals; and during the last weeks of pregnancy it is necessary that the mother should have the opportunity of complete rest.
The increase in weight of the new-born child during the first days of its life, may constitute a valuable prognostic of the child's life. That is to say, through its successive gains it reveals the vitality, the state of health of this new human being.
Here also the pediatrists can furnish us with valuable experimental data, which serve to formulate the "laws of growth." These are:
1. From the moment of a child's birth, throughout the first two days, it suffers a loss in weight of about 200 grams, due to various causes, such as the emission of substances accumulated in the intestines during the intrauterine life (meconium), and the difficulties of adaptation to a new environment and to nutrition. But by the end of the first week a normal child should have regained its original weight; so that after the seventh day the normal child weighs the same as at the moment of birth.
On the contrary, children born prematurely, or those having at the time of birth a weight below the average, or those that are affected with latent syphilis, or are weak from any other cause whatever, regain their original weight only by the end of the second week.
Accordingly, in one or two weeks the family may form a prognosis regarding future life of the new-born child: a matter of fundamental and evident importance.
Furthermore, an antecedent detail of this sort may be valuable in the progressive history of subjects who, having attained the age for attendance at school, come to be passed upon by the teachers.
To this end, in the more progressive countries, the carnet maternel, or mother's note-book, has begun to come into fashion, for the use of mothers belonging to the upper social classes (as, for instance, in England): it consists of a book of suitable design, in the form of an album, and more or less de luxe in quality, in which the most minute notes are to be registered regarding the lives of the children from the moment of their birth onward. Various authors, especially in France, now give models for the maternal registration of the child's physiological progress; true biographic volumes that would form a precious supplement to the biographic charts of the schools: and the efforts of the family would round out and complete those of the school for the protection of the lives of the new generations. Such assistance, however, is only an ideal, because nothing short of a great and far distant social progress could place all mothers (the working women, and the illiterate of Italy) in a position to compile their carnet maternel. Auvard advocates, for registering the weight of the child during the first days of its life, a table in which the successive days from the first to the forty-fifth are marked along a horizontal line, while a vertical column gives a series of weights, with 25-gram intervals, covering a range of 700 grams, the multiples of a hundred being left blank, to be determined by the actual weight of the child and filled in by the mother or whoever takes her place.
Fig. 36.
In such a table, the graphic sign indicating the changes in weight ought to fall rapidly and rise again to the point of departure by the seventh day, if the child is robust.
Another law of growth which may serve as a prognostic document in the child's physiological history is the following:
2. "Children nourished at their mother's breast double their weight at the fifth month and triple it at the twelfth." In other words, before the middle of its first year a healthy child, normally nourished, will have doubled its weight.
On the contrary, "Artificial feeding retards this doubling of weight in children, which is attained only by the end of the first year; so that the weight is not tripled until some time in the course of the second year."
And this gives us pretty safe principles on which to judge of the personality in the course of formation, at an epoch when stature does not yet exist.
Undoubtedly a great moral and social progress would be accomplished through a wide dissemination of very simple and economical carnets maternels; which should contain not only tables designed to facilitate the keeping of the required records, but also a statement of the laws of infant hygiene; or at least, simple and clear explanations of the significance of such phenomena, in relation to the life and health of the child; and also as to the causes which produce weakness in new-born children; or in other words, advice regarding the fundamental laws of the hygiene of generation. All that would be needed, in such case, would be a progressive exposition by means of the carnets, through lessons made as simple and as objective as possible, such as the weighing of small babies, to make the much desired "education of the mothers" both possible and practical.
But without this practical means; without this new sort of syllabarium on hand, to serve as a constant and luminous guide for married women, I do not believe that we shall have much success with the scattered lectures, obscure and soon forgotten, that at present are being multiplied in an attempt to reach the mothers of the lower classes.
In conclusion, I note this last contribution that comes to us from the pediatrists:
3. "There are certain maladies that cause a daily and very notable loss in weight"; they are the intestinal maladies; there may be an average loss of from 180 to 200 grams a day; but even in cases of simple loss of appetite (dyspepsia) the weight may decrease by about 35 grams a day. But when a child suffering from acute febrile intestinal trouble (cholera infantum), loses a tenth of his weight in twenty-four hours, the illness is mortal.
Now from the point of view of the educator this fact ought to be of serious interest, because we very frequently find among the recorded details of sickly children, or those suffering from arrested or retarded development, a mention of some intestinal malady incurred in early infancy.
Still one further observation: Meunier has noted a fact of extreme importance: that while children are passing through the period of incubation of an infectious disease, and before they show any symptoms likely to cause a suspicion of the latent illness, they sustain a daily loss in weight, from the fourth or fifth day after exposure to contagion until the appearance of decisive symptoms. In children between one and four years old, the daily loss is about fifty grams, and the total about 300; but such a loss may rise as high as 700 gr. The most numerous observations were taken in cases of measles.
Now, there is no need of explaining the prophylactic importance of observations such as these! A child who for a period of twenty days is in a state of incubation, is called upon to struggle, with all the forces of immunity that his organism possesses, against a cause of disease which has already invaded him; yet no external sign betrays this state of physical conflict. Consequently, the child's organism continues to sustain the customary loss of energy due to the activities of its daily life, and by doing so lessens its own powers of immunity. To prescribe rest, if nothing more, for a child suspected of passing through the period of incubation would in many cases mean the saving of a life, and at the same time would protect his companions from infection, which is communicable even during the period of incubation.
In our biographic records of defective children, which include the great majority of the weakly ones, we find in many cases a characteristic tendency to relapses in all kinds of infective diseases, from which they regularly recovered. Such organisms, feeble by predisposition, yet sufficiently strong to recover from a long series of illnesses, were exhausted in respect to those biological forces on which the normal growth of the individual depends, by this sort of internal struggle between the organic tissues and the invading microbes. No scheme of special hygiene for children of this type can help us, either in the home or at school; the daily variations in weight, on the contrary, might constitute a valuable guide for the protection of such feeble organisms; at the first signs of a diminution in weight, such children ought to be subjected to absolute repose.
The use of the weighing-machine, both at home and in school cannot be too strongly recommended. In America the pedagogic custom has already been established of recording the weight of the pupils regularly once a month; but instead of once a month, the weight ought to be taken every day. The children might be taught to take their own weight by means of self-registering scales, and to compare it with that of the preceding day, thus learning to keep watch of themselves: and this would constitute both a physical exercise and an exercise in practical living.
The weight may be considered by itself, as a measurement of the body; and it may be considered in its relation to comparative mean measurements given by the authorities; just as it may also be considered, in the case of the individual, in its relation to the stature.
a. The weight, taken by itself, is not a homogeneous or rigorously scientific measurement. In the same manner as the stature, it represents a sum of parts differing from one another, the difference in this instance being that of specific gravity. As a matter of fact, it makes a great difference whether a large proportion of the weight of an individual is adipose tissue, or brain, or striped muscles. Each of the various organs has its own special specific gravity, as appears from the following table:
Specific Gravity Tubular bones 1.93 Spongy bones 1.24 Cartilage 1.10 Muscles from 1.10 to 1.30 Tendons 1.16 Epidermis from 1.10 to 1.19 Hair from 1.28 to 1.34 Liver 1.07 Kidneys 1.04 Brain 1.039 Cerebrum 1.036 Cerebellum 1.032 Adipose tissue 0.97All these specific gravities are low; we weigh but little more than water; and for that reason it is easy for us to swim. But because of the difference in their composition, the total weight of the body gives us no idea of its constituent parts.
Take for example the question of increase in weight. We can compare the mean figures given by the authorities with the ascertained weight of some particular child of a given age, so as to keep an empirical check upon the normality of its growth. But since we know that an individual in the course of evolution undergoes profound alterations in the volumetric proportions of the different organs in
