infant organism, and they advise that the child's body should never be completely protected, as for example that the legs should always be left bare, that the child should be lightly clad, that his apartments should not be heated, etc.

Furthermore, it used to be held in the pietistic schools, and still is to some extent, that warmth had a demoralising influence, inasmuch as it tended to enervate both mind and body.

We educators cannot fail to be interested in such a discussion. As often happens in physiological arguments, the two opposite contentions each contain a part of the truth. In order to get at the truth of the matter, it is necessary to distinguish two widely separated facts: on the one hand, physiological exercise in the form of thermal gymnastics, and on the other, the development of organisms in a constantly cold environment.

To live constantly warm, protected either by clothes or by artificial heat, so that the organism remains always at a constant temperature, is not favourable to growth, because it deprives the organism of the physiological exercise of adapting itself to variations in external temperature, an exercise which stimulates useful functions. By perspiring in summer, we cleanse our system of poisonous secretions, and by shivering in winter we give tone to our striped muscles and to our internal organs, as is proved by our gain in appetite. Anyone who wishes to be kept on ice in summer and to transform his apartment into a hot-house in winter, robs himself of these advantages and enfeebles his system.

The apparent comfort is not in this case a real physiological enjoyment but a weakness of habit that is accompanied by a loss of physiological energy. What makes us robust is a rational exercise of all our energies. Thermal gymnastics is consequently useful. It consists in exposing a healthy, resistant organism to changes in temperature, trusting to our physiological resources for the means of defense. Thus, for example, a child who is well fed and well protected from the cold for many hours of the day in the well-heated family apartment, can go out with bare legs into the snow; and doing so will make him more robust. In the same way, the ancient Romans exposed themselves in their hot baths to the steadily increasing temperature of the calidarium, up to the point of 60 degrees (140 Fahrenheit), and then still perspiring flung themselves into a cold plunge. And it is a familiar fact that afterward they held lavish banquets in these same baths. Such exercise which in classic times gave vigour to the race that made itself master of the world may be summed up as follows: "Thermic gymnastics" of organisms "well nourished and strong."

Our own boatmen also throw themselves into the river in midwinter, half nude, and half nude they ply their long poles. They expose themselves to the cold, in the same way that they might raise a weight of many pounds with their robust arms, for gymnastic exercise.

But all this differs radically from living continually in a cold temperature. It is a very different thing from the life of a child of the lower classes, who goes bare-foot in winter, clad in a few scant rags, half frozen in his wretched tenement, and unable to obtain sufficient nourishment to develop the needed heat-units. He is already deficient in bodily heat because of malnutrition, and the effects of cold are cumulative. In this case it is not a question of thermic exercise but of a permanent deprivation of heat, in individuals who are already suffering from an insufficient development of heat-units. Consequently the organism is enfeebled—it grows under unfavorable conditions—and the result is a permanent diminution of development. Whoever grows up, exposed to cold after this fashion, has, in the average case, a lower stature than those who grow up in the midst of warmth, or in the practice of that healthful exercise which constitutes the ideal: thermic gymnastics.

The contradictory ideas that are held as to the efficacy of heat in regard to growth, are due to a large extent to a prejudice which amounts to this: heat is effective in promoting the evolution of life as a whole, and consequently the development of that part of life that is centred in the organs of reproduction; from which comes the wellnigh antiquated theory that artificial heat should be banished from the schools, as one of the factors leading to immorality! It is true that warmth accelerates the development of puberty; but who is there in this twentieth century who can still conceive the idea that it is a moral act to silence the forces of nature? Good nourishment also leads to a more precocious puberty; and the same is true of the repeated psychic stimulus produced by various forms of intellectual enjoyment, by conversation, and by social intercourse with individuals of the opposite sex. Accordingly, if it were a moral act to retard the development of puberty and to produce a general impoverishment of sexual life, the moral measures to be taken in education would be cold, malnutrition, and the isolation of the sexes in the schools, which, as a matter of fact, form the stumbling-block of environment in our colleges. But it is well known that all this leads on the contrary to moral and physical degeneration! As has already been said, the normal physiological development stands in counterdistinction to immoral habits; consequently, whatever is an aid to physiological development is in its very nature moral.

In warm climates the first manifestations of puberty occur precociously in man as well as in woman; and with them come all the transformations that are associated with puberty, among others the rapid increase of stature. In cold climates, on the contrary, such manifestations are more tardy. The women of Lapland are latest of all to develop. With them, menstruation begins only at eighteen, and they are incapable of conceiving under the age of twenty, while the period of the menopause (involution of sexual life) is correspondingly early; in other words, the entire period of sexual life is shortened. Furthermore, the fertility of the women of Lapland is low; they cannot conceive more than three children. But if these same women leave Lapland and make their home in civilised countries, as for example in Sweden, they have a more precocious sexual life, as well as longer and more fertile, and altogether quite similar to that of the Swedish women.[25]

Cabanis[26] notes that even in cold climates, when young girls spend much of their time in the vicinity of stoves, menstruation begins at about the same age as in women who live on the banks of the Ganges—as is the case with the daughters of wealthy Russians, whose development is quite precocious. In Arabia, in Egypt, and in Abyssinia the women are frequently mothers at the age of ten, menstruation having begun at the eighth year. It is even said that Mahomed married Radeejah when she was only five and that he took her to his bed at the age of eight. The religious laws of India permit the marriage of girls when they are eight years old.

Consequently it is true that heat has an influence upon the development of the organism independently of other influences; in fact, heat acts both in the form of climate, that is, in a natural state, and also in an artificially warmed environment. It is also one of the causes of the different degrees of growth in stature through the successive seasons (see below).

In conclusion: it is enjoined upon us, as a hygienic necessity, to heat the schools in winter, especially the schools for the poorer classes; it means more than increased vigour, it may even mean giving life to some who otherwise would pine away from deprivation of heat-units, a condition most unfavourable to organisms in the course of evolution.

Photogenic Conditions.—Light also has a perceptible influence upon growth: it is a great physiological stimulant. At the present day, physical therapy employs light baths for certain forms of neurasthenia and partial enfeeblement of certain organs; and some biological manifestations, such as the pigments—and similarly the chlorophyl in plants and the variegated colouring of birds—receive a creative stimulus from light.

Light contains in its spectrum many different colours, which act quite differently upon living tissues; the ultra-violet rays, for instance, kill the bacilli of tuberculosis and sometimes effect cures in cases of cancer. Psychiatrists and neuropaths have demonstrated that many colours of light have an exciting effect, while others, on the contrary, are sedative.

Hence there has arisen in medicine a vast and most interesting chapter of phototherapy.

In regard to the phenomena of growth, it has been noted that certain coloured lights are favourable to it, while certain others, on the contrary, diminish or arrest it, as the red and the green.

Phototherapy ought to concern us as educators, especially in regard to schools for the benefit of nervous children: a periodic sojourn in a room lit by calming colours might have a beneficent effect upon epileptic, irritable, nervous children, in place of the debilitating hot bath, or, worse yet, the administration of bromides; while light-baths would be efficacious for weak and torpid children.

But for normal children we must consider the light of the sun as the best stimulant for their growth. A sojourn at the sea-shore, so favourable to the development of children, is now believed to owe its beneficial effects to the fact that the child, playing half naked on the sea-shore, bathes more in the sunlight than he does in the salt water. Gymnastics in the sun, while the body is still only half dry, is what the younger generations should practise on a large scale, if they would bring about the triumph of physiological life.

We must not forget this great principle when, by planning home work for the pupils, we practically keep them housed during the entire day, keeping them for the most part employed in writing or reading; in other words, using their sense of sight, which, if it is to be preserved unharmed, demands a moderate light. The eye ought to rest its muscles of accommodation, and the whole body be exposed to the full light of the sun during the greater part of the day. Let us remember that often the children of the poor live in a home so dark that even in full mid-day they are obliged to light a lamp! Let us at least leave them the light of the street, as a recompense for wretchedness that is a disgrace to civilisation!

According to certain experiments conducted in Rome by Professor Gosio, the light of the sun has an intensive effect upon life. Living creatures reared in the solar light grow and mature earlier, but at the same time their life is shortened; that is, the cycle of life is more intense and more precocious; conversely, in the shade the cycle of life is slower, but of longer duration. A plant matures more quickly in the sun, but its stature is lower than that of a plant in the dark, which has grown far more slowly, but has become very tall and slender and lacking in chlorophyl. Similarly, as is well known, the women in tropical countries attain a precocious puberty, while conversely those of the North attain it tardily; and this fact must be considered in relation to the influence of the sun. A life passed wholly in the sunlight would be too intense; an organism that is exposed a few hours each day to the rays of the sun is invigorated; the interchange of matter (metabolism) is augmented; all the tissues are beneficially stimulated. For this reason sun baths are employed for paralytic and idiot children, and consist in exposing the body of the child, reclining upon its bed and with its head well protected, to the direct rays
