Memorandum. 



Admiralty, Dec. 28th, 1838. 

 The Lords Commissioners of the Admiralty having had under con- 

 sideration the general utility of recording with clearness and precision, 

 in the log books of all Her Majesty's ships and vessels of war, the 

 actual state of the winds and weather, have thought fit to order that 

 henceforward in each page of the log book two columns should be 

 introduced, wherein the force of the wind and the appearance of the 

 atmosphere, shall be every hour registered according to the annexed 

 scheme, a copy of which shall be pasted into each book, and painted 

 on the back of every log board or log slate: and two more columns 

 shall likewise be given for the purpose of entering the heights of the 

 barometer or simpiesometer, and thermometer, when such instru- 

 ments may be on board.

C. WOOD.
