Hence it will be necessary not to limit ourselves, as has been done in the past, to admiring the man who is born good, but to educate him so as to render him thoughtful, strong and useful; not to condemn the sinner, but to redeem him through education and through a sense of fellowship in the common fault, which is the scientific form of pardon. The degenerate, who succeeds in conquering his sinful instinct and in ceasing to do harm, the normal man who renders himself morally sublime by dedicating his splendid physiological inheritance to the collective good, will be equally meritorious. But what a moral abyss gapes open to divide them! Because it is a short stride at best that the physiological proletariat can take, while for the soul of the normal man an untrammelled pathway lies open toward perfection.
Accordingly the new task of the teacher of the future is a multifold one. He is the artificer of human beauty, the new modeler of created things, just as the sublime chisel of Greek art was the modeler of marbles. And he prepares for greater utilisation the physiological and intellectual forces of the new man, like a Greek deity scattering broadcast his prolific riches.
But above all he prepares the souls for the sublime sentiment which awaits the humanity of the future, glorying in the attainment of peace, and then indeed he becomes almost a redeemer of mankind.

CHAPTER VIITECHNICAL PART
In a book the technical part can serve only to point the way, because the acquirement of technique demands practical experience.
The technique of anthropology consists, essentially, of two principal branches: 1. the gathering of anthropological data by means of measurements (anthropometry) and by inspection (anthroposcopy); 2. the formulation of laws based on these anthropological data.
Anthropometry requires a knowledge: a. of anthropometric instruments; b. of the anatomical points of contact to which the instruments must be applied.
For beginners it will be found helpful to mark upon the subject the anthropometric points of contact by means of a dermographic pencil.
In anthropology so large a number of measurements are taken, both from life and from skeletons, that a minute description of them all would demand a separate treatise. We shall limit ourselves to indicating such measurements as it has been found of practical utility to take in school.
The FormIn the theoretic part of this work we emphasized the word form, representing the body as a whole and embodying the conception of relationship between the proportions of the body, tending to determine the morphological individuality.
From the normal point of view the two individualities which are most interesting and worthy of comparison are those of the new-born child and the adult (see Fig. 140 and its eloquent testimony). In these two individualities the greatest possible prominence is given to those differences of proportion between bust and limb on which all the various measurements of the form depend: the standing and sitting stature; the total spread of the arms; the weight; the circumference of the thorax (see "Theoretic Lessons on the Form"). With the theory recalled to mind we may now pass on to the practical procedure for obtaining these various measures. Among them the most important is the stature, whose cycle is represented in Fig. 141. The theoretic section of this book devotes special attention to the stature in a separate chapter following that on the Form. It is well to have in mind the general principals before taking up the technique of the separate measurements.
Stature.βThe stature is the distance intervening between the plane on which the individual stands in an erect position and the top of his head.
Fig. 140.βNew-born child and adult man reduced to the same height and preserving their relative bodily proportions. The head of the new-born child is twice the height of that of the adult and extends downward to the level of the latters's nipples. The pubes of the adult correspond to the navel of the new-born child; and the pubes of the child to the middle of the adult's thigh.
Technical Procedure.βIt is necessary to know how to place the subject in an erect position, heels together and toes turned out, shoulders square, arms pendent, head orientated, i.e., occipital point touching the wall, gaze horizontal.
In measuring the individual stature it is customary to use an instrument called an anthropometer (Fig. 142).
It consists of a horizontal board on which the subject stands, a stationary vertical rod marked with the metric scale against which the subject rests his back, and another small movable rod perpendicular to the first and projecting forward from it; this is lowered until it is tangent to the apex of the cranium; and the scale upon the upright rod gives the number corresponding to the stature.

Certain anthropologists are now trying to perfect the anthropometer (Mosso's school). And, indeed, how is it possible to bring the entire person posteriorly in contact with the vertical rod of the anthropometer? The rod is straight while the body follows the curves of the vertebral column and the gluteus muscles. Accordingly, Professor Monti, an assistant to Professor Mosso, has proposed a new anthropometer which, in place of the single rod at the back, has a pair of rods, so that the more prominent portions of the body may occupy the intermediate space; a similar anthropometer was already in use for measuring kyphotics.

At the present day there are exceedingly complicated and accurate anthropometers which comprise, in addition, instruments for obtaining various other measurements, such as the thoracic and cephalic perimeters, etc. But these are very costly and not practical for use in schools. Their use is confined chiefly to medical clinics, as, for example, Viola's anthropometer, which is used in Professor De Giovanni's clinic.
Broca recommends to travelers an anthropometer consisting of a graduated rod with a movable index attached. By means of this a series of distances from the ground can be measured, and consequently various partial heights of the body, from the ground to the top of the head, from the ground to the chin, to the pubis, to the knee, etc., but grave errors may be committed and its use is not advisable so long as we have within reach a universal anthropometer.
The universal anthropometer consists essentially of two planes perpendicular to each other; now we may say that in every room, in the meeting of two planes, the floor and the wall, we have an anthropometer. There is no reason why we should not make use of this simple means! Placing the child in an erect position with the body touching the wall throughout its whole length, we place a perfectly horizontal rod tangent to the top of the head, we make a mark upon the wall, and then with a millimetric measure we take the distance between the mark and the floor, and this gives us the stature. Two difficulties are met with, first, that of holding the rod horizontally on the top of the head, and secondly, that of measuring the distance in a perfectly vertical line. In the first difficulty a carpenter's square may help us or, if there is a school of manual training within convenient reach it is easy to have a little instrument constructed (Fig. 143) consisting of two planes perpendicular to each other, one of which should be held tangent to the head while the other is pressed against the wall (carpenter's square).
As regards the vertical measurement, a plumb line may be used, but it is more practical to trace upon the wall that we mean to use for such measurements, a design consisting of a vertical line on which a mark may be made at the height of one metre from the floor in order to simplify the task of measuring.
It is better if the millimetric tape is made of metal, so that it will not vary in length; but even a tailor's measure of waxed tape may answer the purpose if it is new and has been tested with a metallic measure or an accurate metre rule.
The height of the stature is taken without the shoes, and it is necessary to state at what hour of the day the measurement is made, because in the morning we are taller (though by only a few millimetres) than we are in the evening. The stature may also be taken in a recumbent position (length of body), and in this case will be longer by about one centimetre.
Consequently in giving the measure of stature it is necessary to state in what position the subject was placed, by what method the measurement was taken (whether with an anthropometer or not) and at what hour of the day the measurement was made.
It is not necessary to say that the subject was required to remove his shoes, since that is taken for granted.
Sitting Stature.βBesides the stature taken on foot, the sitting stature (height of bust) is also taken by an analogous process. It is the distance between the plane on which the individual is seated and the vertex of his head. The subject should be seated upon a wooden bench having a horizontal plane and should place his back in contact with the wall; just as in the case of the preceding measure the shoes had to be removed, in the present case the clothing is discarded, leaving only the light underwear (Fig. 144). With the aid of the square we find the point corresponding to the vertex of the head and with the millimetric measure we obtain the distance on the wall between this point and the plane of the bench.

Index of Stature.βWe know that these two measures are extremely important for ascertaining the type of stature, i.e., macroscelia and brachyscelia, determined by the proportion between the sitting stature and the total stature reduced to a scale of 100, that is, the relation of the bust to the total height of the individual. Let us remember in this connection that the bust should be a 52d or 53d part of the total stature and that below 52 down to 50, it is macroscelous, and that above 53, up to 55, it is brachyscelous.
Having obtained the two numbers corresponding to the two statures, e.g., stature 1.60 m., bust 0.85 m., how are we to find out the percentual relation between the two measurements? First, we form an equation: 85:160 = x:100.
from which we obtain x = (100Γ85)/160 = 53
This stature is of the normal average type, that is, it is mesatiscelous; but the mesatiscelia is high (in comparison with the other measurement that is also mesatiscelous, namely, 52), in other words, it is brachy-mesatiscelous.
Note the formula which gives us the value of x. If we substitute general symbols in place of the concrete values, we may say that x is equal to one hundred times the lesser measurement (m) divided by the greater measurement (M). If, in place of x, we substitute I, signifying
