Turning now from these curves to a complex educa-tional estal>lishment, we find for its corresponding fixed ele-ments, 1°, a foundation ootcrse of study^ alike for all, 2°, ateaching and governing body. There would then be depend-ing upon these {a) the various specialties to which the institu-tion might devote itself; {h) the Incidental features of its life,lodgings, gymnasium, etc.; and finally (c) a select group of struc-tures, devoted to the most refined purposes of the institution. 107. Parabolic jplan. The several elements just statedmight find their material organization on a jparaJ^olic jplan^ asfollows. The collegiate or general building in which the foun-dation course (1°) should be given, would naturally stand at thefocus. The residences of the teaching and governing body (2)would be located on an avenue marking the directr
