 the autumn-period, i.e., the period before hibernation. 



Tablk iii. 

 Average Autumn-temperatures of Echithta. 



It will be seen that the individual averages do not differ much 

 from one another. Single observations, however, may differ as 

 much as 3" from the average values. The average morning- and 

 afternoon-temperatures from 61 observations distributed over 

 four animals are shown to be 29 •9" and 32'7°C. respectively. 

 The average temperature of the air for this period was about 

 18'*C. 



In Table iv., are given the average morning- and afternoon- 

 temperatures for individual Echidnas, and for the whole number 

 in the Table for the Spring- and Summer- period, i.e., after hiber-
