Volcanic Mud, bottom temperature 39°‘5 (Station 170a), midway between Macaulay and 
Raoul or Sunday Islands. Obtained serial temperatures at intervals of 50 fathoms down 
to 500 fathoms. At 4.30 p.m. hove up trawl containing many specimens, and at 
4.35 p.m. proceeded under steam. No albatrosses were noticed to-da} r , and yesterday
