days, l»ut (lie rehitively siiuill diiferences from the 4''' to the 7 '' day 

 justify the calculation of an average for this period of germination. 



Number of calories given off per hour calculated per kilogram 

 of the initial weight. 



The generation of heat, theiefore, was much influenced by (he 

 surrounding temperature ; by a rise of 10°, the quantitj' of heat 

 evolved, increased to more than double. The generation of hea( was 

 diminished at 40°, a proof of the harmful intluence of (his temperature. 



Finally a comparison can be made between the number of calories 

 pro kilogram of initial weight given off as heat and the loss of 

 energy deduced from the heat of combustion. This comparison could 

 only be made for a temperature of 20° because at (his temperature 

 germination had always taken place, so that the heat of combustion 

 referred to processes at this temperature only, 



Loss of energy per hour per kilogram of the initial weight.
