 to deduce these streams only from the greater hydrostatical pressure of 

 the heavier water. He carried that theory, which seemed natural for 

 the course of the developement of science, |as far as it well could be 

 carried. The explanation of the origin of the ocean-streams was moreo- 

 ver only a subordinate side of the magnificent diligence, that Maury 

 displayed ; otherwise he would have discovered the kernel of truth, which 

 lay hidden under the theory's indefinite form.
