 people he is exposed to abrupt changes. 



The last three curves on fig. 7 illustrate these conditions. 



The broken lines of the curves indicate sleep. It is seen that 

 in curve 5 the decidedly highest temperature falls in the "dog-watch",

 stoker curve, owing to the much more regular work and the high 

 air temperature, the rises are most uniform and the average level 



highest.
