I am also wholly unable to comprehend how Dr. Carpenter 
should imagine, because the bottom-temperature of the South At-

the surface in this ocean than in the North Atlantic, that there- 
fore this proves the truth of his theory. This condition of mat-

readily understand how the polar water comes nearer to the sur

stratum of heated water there would be no difference between the 
equatorial and polar columns, and consequently nothing to pro- 
uce motion. But the thinner this stratum is the less is the differ- 
ence, and the less there is to produce motion. I have been fav-
