Until, therefore, Prof. Wyville Thomson shall have been able 
to disprove these results of combined theoretical and practical 
research, by showing that differences of specific gravity, produced 
by differences either of temperature or of salinity, will not produce 
movements in oceanic water tending to the restoration of its di 
turbed equilibrium, I venture to affirm that his dictuin will not 
find acceptance with the physicists who have most carefully 
studied the question. His present doctrine, that the underflow of 
primum mobile is the excess in the specific gravity of polar per 
causing its continual descent and a complemental ascent in the 
equatorial zone,
