 contrary. 



Figures to the Forth of the white line, and West of 

 the line Calf of Man-Holyhead, are Mr. Holt's, and

In all the above plates the figures to the South of the 

 white line have been taken from Matthews' reports 

 {Log. cit.). Figures used by Matthews in drawing his 

 isohalines are marked by a dot and circle. Figures given 

 in his tables, but not, apparently, utilised for the charts, 

 are marked by a dot alone. 



A small underlined figure indicates that the station 

 is one at which samples from various depths are collected ; 

 the number in these cases is the number of the station in 

 the " Bulletins trimestriels du Conseil permanent inter- 

 national pour 1'exploration de la Mer."
