middle period lasts four months, til
 the end of March, and the maximal pc. | riod lasts four and a half months, tt
 the middle of August.
 Increase in weight varies with loca
 temperature, so that all these change. | the author ascribes to the sun.
 Mailing Hansen suggests In the in-
 terests of proportion that children who
 are in danger of remaining short and
 thick go gradually south to warmer
 climates toward the end of summer | and so be removed from the influence | of the maximal period of growth in | thickness. Conversely, a tall,. slender
 child must be removed from the infiu-
 ence of the maximal period of growth in height by being taken slowly north | In April.
 This theory of possible regulation by travel is interesting. However. Prof. Hall remarks that its practicability remains yet to be tested" | Many studies show a diminished rate of growth beginning at six years or seven and continuing with various os- cillations until about ten years in girls and twelve in boys.
 Certain Milwaukee studies led to the conclusion that boys are taller than girls till the twelfth year and heavier till the thirteenth. but from thirteen to fifteen girls are both taller and heav- fer. Afterward the boys exceed in both height and weight. and girls almost cease to grow at seventeen.
 Swedish boys grow heavy fastest through the sixteenth and part of the seventeenth year. They reach the max imum rate of growth in height from the fifteenth to the seventeenth year. and pass American boys in height and weight In the nineteenth year.
 There are many opinions as to the age at which growth in height stops pr. Edward Hitchcock. who measures Amherst students, insists that growth continues up to twenty-six years whether longer or not, our data do not shOw."
 pr. Beyer writes that in a list of height average based upon 5000 re- cruits, 1t appears that while there is no increase from twenty-four to twen- ty-five (nearest birthday there is an increment of one-tenth of an inch at the twenty-sixth year. He says he knows that exercise has been followed by a very slight increase in height at a late period in life, and suggests that if poor personal hygiene or bad con ditions prevented men from attaining predestined heights during the usual periods of growth the change to more favorable influences may cause a re- awakening Of dormant, undeveloped centres and in this manner aid nature in making up for lost opportunities at later period than is usual"
 ''Is the race of are Americans grow ing?"
 Dr. Anderson. physical instructor of Yale, thinks the Yale men of today average nearly an inch taller than those of twenty years ago. also that  they are heavier and mere muscular Mir. GOldie. for thirty-four years gym nastic director at Princeton. says that thirty years ago the average student was , feet 71a inches tall and weighed about 140 pounds. whereas today tAe average student is half an inch to an inch taller and weighs not less than l45 pounds.
 Prof. P. C. Phillips. of Amherst, thinks the young women of our col leges are almost certainly an inch taller and four or five pounds heavier than they were ten years ago" and that "the young man of today is taller and heavier than the man previous to 1894"
 The average height of the American soldier is feet 71a inches in his stock ings. He is both heavier and taller and has larger chest measure than the soldier of any other country save only Scandinavia.
