This work is conceived essentially as a historical study of the origin and development of one of the key concepts in Husserl's philosophy. It is not primarily meant to be an introduction to Husserl's thought, but can serve this purpose because of the nature of this concept. The doctrine of constitution deals with a philosophical problem that is fairly easy to grasp, and yet is central enough in the philosophy of Husserl to provide a con venient viewpoint from which other concepts and problems can be considered and understood. Husserl's thoughts on the phe nomenological reduction, on temporality, on perception, on evi dence, can all be integrated into a coherent pattern if we study them in their rapport with the concept of constitution. Further more, the concept of constitution is used by Husserl as an ex planatory schema: in giving the constitution of an object, Husserl feels he is giving the philosophical explanation of such an object. Thus in our discussion of constitution, we are studying the explanatory power of phenomenology, and in relating other phenomenological concepts to the concept of constitution, we are studying what they contribute to the philosophical expla nation that phenomenology attempts to furnish. To approach Husserl's philosophy in this way is to study it in its essential and most vital function."

die ein Ansteigen der Krankheitszahl zeigen. Dabei ist eine Kombination von ungiinstigen Faktoren, wie schroffer Temperaturwechsel, gro.Ber Feuchtigkeits gehalt der Luft usw. im Spiele. Kommt hinzu die eigentiimliche Gewohnheit, sich in den Tropen in der Nacht ungeniigend gegen Temperaturabfall zu schiitzen, so daB die groBere Frequenz der akuten Erkrankungen ohne weiteres erklart wird. Gliicklicherweise scheinen, wie wir spater sehen werden, die Infektions keime im allgemeinen gutartiger Natur zu sein, weshalb man nur selten ernstere Komplikationen sieht und keine groBe Neigung zu Chronizitat besteht. Weiterhin mu.B die groBere N eigung zu Blutungen nach chirurgischen Ein griffen erwahnt werden. Sie macht es notig, vor jeder, auch der kleinsten Ope ration Calciumsalze zu geben und auch viel ofter als im milderen Klima zu tamponieren. Die Ursache mag wohl einer Zahl tier /'iille seits in einem geringeren Tonus der Gefa.B 28 muskeln, und andererseits in einem ge 27 ringeren Calciumgehalt des Blutes, wie \ 26 DE LANGEN und SCHUT fiir Java angegeben \ 25 \ haben, liegen. . 2'1 J Schlie.Blich mochte ich die Aufmerksam 23 II keit auf die Tatsache lenken, daB man immer 22 \. mit einer Komplikation mit Malaria rechnen 21, 20 muB, was bei der Beurteilung von fieber 19 haften Zustanden von Bedeutung sein kann 18 und bei Tropenleuten auch in Europa immer 17 zur Blutuntersuchung notigt."
