assistant physician, dr. H a n n a B e r g h o f f . It should be remembered 

 that it had to be done in the schools, partly under unfavourable light 

 conditions -^. Anv entirely faultless, esthetic, respective artistic photo- 

 graphic achievement can therefore not be rendered. But on the other 

 side, the objectivity is larger than any hitherto presented series of in- 

 vestigations of this kind; this can safely be stated. Only 24 of the 

 photographs are here reproduced, partly on account of several poor 

 results and partly on account of the superfluousness of presenting many 

 tvpes of similar development. Especially for the pre-puberty age of 

 girls it will be noticed, that they are good types averagely in regard to 

 secondary sex marks; even if the majority of the medium types are very 

 close to each other in this respect, some are, of course, out of harmony 

 either by an especially early or an especially slow development. 



When we now look at these middle types (figs. 18 a and b), we would 

 almost have to do violence to our own observation, if we should insist, 

 that any oscillation of "Streckung" or "Fülle" was strikingly noticeable. 

 Not even when we know the schedule and thereby could have all desirable 

 auto-suggestion, can we see it. (With boys the "second Fülle" should 

 begin at 8 years and come to an end at 12 years, after which the "second 

 stretching"; with the girls the "second Fülle" should also begin at 8, 

 but for this sex be concluded already at 10. after which "second stretch- 

 ing", which should last till 14, whereafter the "third plumpness" is due.) 

 What is it, however, we can say with certainty that we see? Well, un- 

 doubtedly that there between the 7 years and the 14 years old boy is a 

 difference in plumpness and proportions. The last one is more slender, 

 has a relatively smaller head and longer under-extremities. The difference 

 sets in graduallv through the years. If one has not been influenced 

 suggestively by the Bartels-Stratz schedule •■'' — it is presented with 

 apparent trustworthiness and repeated with dogmatic authority in several 

 textbooks, as Marti n's and Broman n's — then we have verily not 

 anv "experience" either, that the general development runs in this wave 

 motion. We should therefore take care to get this notion done away 

 with as soon as possible, the whole is a construction without foundation. 

 Several waves up and down in "Fülle" could impossibly give curves for 

 weight-height index as corresponding to fig. 14 for our large material. 

 Even if "Fülle" and weight-height proportions, specially for the single 

 individual, are not conceptions which necessarily cover each other, the 

 mentioned conceptions will in the mass material without doubt show a 

 high degree of parallelism. 



The n:edical department cf schools now take up so much of the time of the schools, 

 that any extra charge on its time must be avoided. 



The author has not escaped this suggestion himself, before his own investigations 

 had advanced verv much.
