definite factor in producing mal-nutrition, the insufficient food-energy being first taxed to keep up
the animal heat.

Mental capacity as affected by physique. —The mental capacity was gauged by the class teachers. The marks 1 to 5 were given in the following manner:—

No.Percentage.
Very dull and backward235
2. Below the average7017
3. Average intelligence17343
4. Above the average9824
5. Brilliant4110

It must be remembered that the actual mentally defective were already weeded out and sent
to special schools.
No correlation can be established between mental capacity and physique in this school; the
93 below average intelligence correspond with the average age, weight, and height for the school.
The 98 boys given as above the average (class 4) have a decided advantage in physique, 1.5 centimetres
in height and .5 kilos, in weight, the exceptionally brilliant boys (numbering 41), however,
are actually slightly below the average physique—a quarter of a kilogram in weight and .4 centimetres
in height.

The effect of overcrowding upon physique.-

„ 3 „ „350+1
„ 4 „ „84+1.3+2

Here, again, we see that only at the extremes can any effect be made out upon the physique; more important than the number of rooms of course is the number of occupants per room:-

There is seen here a slight effect only until we reach the serious overcrowding of more than
five to a room, when the divergence becomes startling. It may be of some interest to give full
particulars of these ten cases:—
