TEMPERATURB OP ECHIDNA ACULEATA, 



The temperatures of the animals were observed during two 

 periods of the day, in the morning between 10 a.m. and 11 a.m., 

 and in the afternoon between 2 p.m. and 3 p.m. The temper- 

 ature of the air in the animals' shed, at a height of about 120cm. 

 from the floor, was always read just before taking the tempera- 

 ture of the animals. It should be remarked that the temperature 

 of the air above the animals may be considerably different from 

 that of the sawdust covering the floor of the shed. On one hot 

 day, for example, the temperature of the air was 37'4°C., whilst 

 that of the sawdust was only 21-9°C.
