NOTES. 



Wlien dredgings have been made, soundings, both at the start and finish of the haul, have generally been taken. So that 

 when, for instance, Oxsund 450— «30 m. is noted, it is to be understood that the deptii was 630 m. where the dredge was thrown 

 out. and 450 ni. where the dredging was ended.
