same way, organic impoverishment is caused by certain maladies of the digestive system which impede the normal assimilation of nutritive matter: dysentery, for instance; and the effects may be still more disastrous if symptoms of this kind are accompanied by feverish conditions, as in typhus.

There are cases, however, in which the arrest of development is not to be attributed to some wasting disease, or to the denutrition resulting from it; but rather to some acute illness occurring in early childhood (pneumonia, etc.), after which the child ceased to progress in accordance with his former obviously normal development.

Anangioplastic Infantilism.—Another form of infantilism is associated with a malformation of the heart and blood-vessels, that is to say, the heart and aorta together with the entire circulatory system are of small dimensions; the calibre of the arteries is less than normal. In such a case the restriction of the entire vascular system and the scantiness of circulation of the blood constitute an impediment to the normal growth of the organism. Although in such cases the explanation of the cause of the phenomenon is purely mechanical, nevertheless such abnormality of the heart and veins is to be classed as a teratological (monstrous) malformation, determined by original anomalies of the ductless glands, similar to what is found in cases of cephalic and cerebral monstrosities.

In this form of infantilism the patient shows not only the usual fundamental characteristics already noted, but also symptoms of anemia as obstinate to all methods of treatment as chlorosis is; in addition to which they often show congenital malformations of the heart, in every way similar in their effects to valvular affections such as may result from pathological causes (chief of which are mitral and aortic stenosis, which consist of a stricture of the valves connected with the left ventricle of the heart).

Accordingly, children who show forms of mitral infantilism are inferior to their actual age not only in their whole psychosomatic appearance, but they are noticeably weak, pale and suffering from shortness of breath and disturbances of the circulation. In such cases, neither pedagogy nor hygiene can counteract the arrest of development; but it is well that the attention of teachers should be called to such cases, in order that cruel errors may be prevented, which would unconsciously do additional harm to individuals already burdened by nature with physiological wretchedness.

In conclusion: The normal growth of the organism is associated with the functional action of certain glands known as glands "of internal secretion," such as the thymus and thyroid, first of all, as well as the suprarenal capsules and the cerebral hypophysis.

This group of formative glands presides not only over the entire growth of the body, but also over the intimate modeling of its structure; so that a lesion or deficiency in any of them results not only in nanism and an arrest of mental development, but in various forms of general dystrophy.

That the organism is associated in the course of its transformations with the functional action of specific glands is shown by the development of puberty, which consists in a series of transformations of the entire organism, but is associated with the establishment of functional activity of glands that were hitherto immature: the genital glands (ovaries, testicles). These glands also are functionally in close sympathy with the entire group of formative glands: so much so that, if the glands of internal secretion are injured, the genital glands usually fail to attain normal development (infantilism). Now, the transformations which take place in the organism at the period of puberty might be produced at other periods if the functional action of the generative glands should show itself at a different epoch. That is, these transformations are not associated with the age of the organism, but with the development of specific glands. There are cases of the genital glands maturing at abnormal ages; or of local maladies that have hastened the appearance of the phenomena of puberty in children of tender years. A notable case is that described by Dr. Sacchi,[32] of a nine-year old boy, who had grown normally up to the age of five and a half, both in his physiological organism and in his psychic personality. At the age of five and a half, the child's father noticed a physical and moral alteration; the child's voice grew deeper, his character more serious, and the skeletal and muscular systems grew rapidly, while on certain portions of the body, as for example on the face, a fine down appeared. At the age of seven the child had attained a stature that was gigantic for his age; he was very diligent and studious and did not care to play with his comrades. At nine, he had a stature of 1.45 metres (the normal stature being 1.22), a weight of 44 kilograms (normal = 24); his muscles were highly developed, his powers of traction and compression being equal to those of a man; his chin was covered with a thick beard five centimetres long. When he was examined by a physician, the latter discovered a tumor in the left testicle. After an operation, the child lost his beard and regained his childish voice; his character became more timid and sensitive; he began once more to enjoy his comrades and take part in boyish games. His muscular force underwent a notable diminution.

Rickets.—It is important not to confound any of the various forms of infantilism with rickets. Rickets is a well-defined malady whose special point of attack is the osseous system in course of formation; but it leaves the nervous system and the genital system unimpaired. The sufferer from rickets may be a person of intelligence, capable of attaining the highest distinctions in art or in politics; he is normal in his genital powers, so that he is capable of normal reproduction, without, in many cases, transmitting any taint of rickets to his descendants.

Nevertheless this disease, like all constitutional maladies, occurs only in individuals who are weakly.

Among the characteristics of rickets, the one which assumes first importance is inferiority of stature in comparison with the normal man. In this connection I quote the following figures from Bonnifay:[33]

Age Stature in centimetres Rachitic children Normal children 11 months 66.5 69.4 2 years 70.7 74.8 2-3 years 75.8 83.0 3-4 years 76.8 91.9 5-6 years 91-93 101.25 6-7 years 105.0 106.8 7-8 years 110.6 115.3 8-9 years 118.4 119.0 9-10 years 121.6 124.4

But together with diminution of stature there exist in rickets various deformities of the skeleton, especially in the bones of the cranium, in the vertebral column and in the frame of the thorax; although even the pelvis and the limbs have been known to show the characteristic deformities.

An objective knowledge of the first symptoms of rickets ought to be regarded as indispensable on the part of mistresses in children's asylums, and in any case to form an important chapter in pedagogic anthropology. For it is well known that in the early stages of rickets the child may be so guided in its growth as to save it from deformities of the skeleton, even though a definite limitation of the stature may not be prevented.

That is to say, that through the intervention of hygiene and pedagogy the rachitic child may be saved from becoming a cripple or a hunchback, and will simply remain an individual of low stature; with certain signs and proportions of the skeleton indicative of the attack through which he has passed. Even in very severe cases it is at least possible to minimize the deformity of the thorax and the curvature of the vertebral column.

The precursory signs of rickets in a child are: a characteristic muscular weakness, frequently accompanied by excessive development of adipose tissue, giving an illusory impression of abundant nutrition; delay in the development of the teeth and in locomotion, which from the very beginning may be accompanied by curvature of the long bones of the legs. The bregmatic fontanelle of the cranium closes later than at the normal period, and is larger than in normal cases, just as the entire cerebral cranium is abnormally developed in volume, while the facial portion remains small, especially in regard to the jaw bones.

One of the most salient characteristics, however, is the peculiar enlargement of the articular heads of the long bones, easily recognizable in the size of the wrists; the enlargement is also found in the extremities of the ribs, which at their points of union on each side of the sternum form a succession of little lumps, like the beads of a rosary. In conjunction with these characteristics, it is to be noted, at all ages, as appears from the figures given by Bonnifay, that there is a notable diminution of stature.

The treatment of rickets is medical and pedagogical combined. Children of this type should be removed from the public school, where the school routine might have a fatally aggravating effect upon the pathological condition of such children. In fact, gymnastics based upon marching and exercising in an erect position, together with a prolonged sitting posture, are likely to produce weaknesses of the skeleton and deformities, even where there are no symptoms of rickets!

The establishment of infant asylums for rachitic children is one of the most enlightened movements of the modern school. We Italians are certainly not the last to found such institutions, and Padua possesses one of the oldest and most perfect asylums of this sort of which Europe can boast. Asylums for rachitic children ought to have a special school equipment, so far as concerns the benches and the apparatus for medical and orthopedic gymnastics; furthermore they should be provided with a pharmaceutical stock of remedies suited to building up the osseous system and the organism in general; and a school refectory should be provided, adapted to the condition of the children. The methods of instruction should rigorously avoid any form of fatigue, and instead provide the child with psychic stimuli designed to overcome a sluggishness due to the mental prostration to which he is for the most part subject. As regards their situation, these asylums for rachitic children may be advantageously located upon the sea-coast.

The Stature of Abnormals.—The name of abnormals is applied to the entire series of individuals who are not normal: hence the categories already considered (infantilism, gigantism, rachitis) are included by implication. The group of abnormals, however, includes besides a long series of other classes, neuropathics, epileptics, and degenerates.

Under the head of abnormals may also be included those who are abnormal in character, such as criminals, etc. It is not irrational to group together the different types of abnormals, for the purpose of anthropological research, in contrast with those who are normal. In America, for instance, such studies are conducted on a large scale, precisely for the purpose of showing the deviation of abnormal dimensions of the body from normal dimensions, not only in the definitive development of the body, but also during growth. The abnormals depart from the mean measurements, now rising above and again falling below, as though they were intermittently impelled by the biological impulse of their organism, which at one time manifests a hypergenesis and at another a hypogenesis. A clear illustration of these facts is afforded by MacDonald's diagram (see page (168)): the solid line which rises regularly represents the growth in stature of normal individuals; the dotted line which forms a zig-zag, now rising rapidly above the normal line and then falling very much below it, represents the growth in stature of the abnormals. Naturally such a chart must be interpreted by comparison with the standards of mean measurements gathered at successive ages from a large number of different children. It shows that normal children are nearly uniform among themselves, and in relation to the years of their growth: while abnormal children differ greatly one from another and do not accord with the mean stature of the age they represent.

Regarding the stature of criminals there can be nothing special to
