Zusammenfassung:	It is possible to make direct measurements in the reaction zone of a Bunsen flame by using a ‘low-pressure flame’, because the flame is then drawn out and enlarged. The temperature-course through the flame front is measured. The position of the Schlieren picture is deduced and may be compared with the actual photographed Schlieren picture. The heat flow in the reaction zone is calculated; it is found responsible for the formation of a considerable preheating zone.
