RECORD AND DISCUSSION OF TEMPERATURES 



The registers herewith presented include observations extending over twenty- 

 seven months, and amount to a total number of upwards of seven thousand. The 

 time is given in civil reckoning, and the latitude and longitude refer to noon each 

 day (unless otherwise stated). All necessary explanations are contained in the 

 notes accompanying the tables in which the observations are given. 



The following statement is made in the preface to the Record : The registering 

 thermometers were frequently compared with the standard thermometers supplied 

 from Kew Observatory, and may be considered as free from sensible error. The 

 corrections were deduced from the following table, furnished by Captain McClin- 

 tock : —

ON BOARD TnE YACHT FOX. 



The Kew Standards were most beautiful instruments, too valuable to leave exposed. Newman's, being filled with 

 colored spirit, were more easily read off during winter. No. Hi having been used in 1850-51, enables us to 

 compare the temperatures of that winter with those of the Fox.
