ter on December 4, 1 9 1 3 43 (also a mild year), than in the coastal belt on that same 
day in 1923. Temperatures of about 5° to 7° may therefore be expected around 
the shores of Massachusetts Bay, with about 8° in its center, by the first week in 
December in average years, with the water virtually homogeneous from surface to 
bottom. 
The data for the Fish Hawlc stations show that almost no change took place 
either in the actual temperature of Massachusetts Bay or in its vertical distribution 
during the first two weeks of December, 1925, the readings being fractionally higher 
for the second cruise than for the first at some stations, lower at others. The 
regional distribution remained unaltered, with the coldest water (5° to 6°) taking 
43 Station 10048; 8.1° at the surface, 7.8° at 46 meters and 70 meters.
