 ^ on the voyage of the Nimrod, commencing on 

 January 1, 1908, from Port Lyttelton down to winter 

 quarters at Cape Royds. These observations were taken 

 hourly. On the return voyage from Ross Island to Port 

 Lyttelton observations were taken during every watch. 

 On the return voyage of the Nimrod from Lyttelton to 

 Ross Island, on her cruises in the Antarctic, and the 

 return voyage to Lyttelton, meteorological observations 

 were taken at intervals of four hours. 



At winter quarters. Cape Royds, systematic observa-

 at night being taken by whoever happened at the time

 meteorological work, was in charge of the meteorological 

 observations and records.
