THE VOYAGE OF H.M.S. CHALLENGER. 
. 1 1 u rat < -il with air at t x degrees. This calculated oxygen is in general greater than the 
oxygen actually found, as stated in Column VII. The oxygen deficit in the water 
is registered in Column X. 
The headings of the several columns in Table XIII. for the bottom waters have the 
'nine meaning as the same symbols have in Table XII. 
When the absolute volume V of the gas remained undetermined, then, in the case of 
'Table A’/., I took the “ nitrogen found ” (Column IV.) from the entry, for t 0 , in Table IX. 
These numbers and those derived from them are enclosed in brackets, [ ]. In Tables 
XII. and XIII. (when V is unknown) 1 give in Column VII., in lieu of the “oxygen 
found, the percentage of oxygen found in the gas freed from carbonic acid, in paren- 
thesis, ( ), with the symbol % attached.
