In this equation, -^ is given by equation (8); its value 

 Wo 

 depends on the magnitude of the temperature coefficient of 

 the reaction. It is not possible to integrate the equation 

 completely, but the integration can be carried out by approxi- 

 mate methods for any value of ^- . In the table below are

If our views are correct, these should form standard curves 

 representing the delays which should be observed under 

 different conditions when any explosive mixture of gases is 

 compressed to a temperature above its lowest ionition 

 temperature. The application of the theory to any specific 

 case should enable the temperature coefficient of the reaction 

 to be determined.
