NOTES. 



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

 when, for instance, 0xsund 450—630 in. is noted, it is to be understood that the depth was 630 in. where the dredge was thrown 

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