and another of 32° F. Both these temperatures were checked on 

 board the reporting ships on special request from the General Greene. 



The surface-temperature conditions for the period June 19 to 29, 

 shown on Figure 26, are based on 204 radio reports and 159 observa- 

 tions from the General Greene. 



On Figure 27 is shown the surface temperatures of the Northwestern 

 Atlantic for the period July 4 to August 12, 1931, mainly according 

 to observations taken on board the General Greene during the northern 

 ocean ographic cruise.
