Although the temperature of the waters of the ocean is 
a highly curious and important subject, it is not, I beheve, 
many years since it claimed the attention of navigators. I 
have frequently experienced the utility of noting its changes, 
and have no doubt the same has been felt by many others. 
As you are collecting observations on this subject, and ex- 
pressed a wish to know the results of some of my observa- 
tions, I now send you the following Table, viz. of those 
made on the surface-water of the sea between St Helena 
and England. 
The observations were made at three different periods of 
the day, viz. at 8 a. m. noon, and 8 p. m.
