These chronometers being embarked, and permanently fixed, more 

 than a month previous to the Beagle's departure from England, 

 sufficient time elapsed to ascertain their rates satisfactorily. 



Suspended in gimbals, as usual, within a wooden box, each was 

 placed in sawdust, divided and retained by partitions, upon one of 

 two wide shelves. The sawdust was about three inches thick below, 

 as well as at the sides of each box, and formed a bed for it which 



* The 12 hour mark of each chronometer was invariably kept in one 

 direction with respect to the ship.
