PHYSICS. 
The Movement of the Ocean . — This question has recently been brought 
under notice by the valuable researches of Dr. Carpenter. It has raised a 
number of supporters in different parts of the world ; among others Professor 
J. D. Dana, in the United States, who makes the following remarks [at 
least we take it for granted that the signature is Professor Dana’s], in 
“ Silliman’s Journal : ” — “ The view which Dr. Carpenter advocates, that 
the movement of the ocean affects the whole body of water to its very 
bottom, is recognised by the writer in his ‘ Report on "Crustacea of the 
Wilkes Exploring Expedition’ (4to. 1618 pp., 1852, ‘Silliman’s Journal,’ 
II. xvi. 1853), and the general system in this circulation is there pointed 
out — this system according with the views previously held by the dis- 
tinguished meteorologist, W. C. Redfield. The conclusions are sustained 
by facts relating to the temperature of the ocean observed in the course 
of the cruise of the exploring expedition just mentioned, and others from 
various sources, presented on an isothermal chart prepared for illustrating 
the geographical distribution of marine life, and especially the Crustacea ; 
and a brief statement of this system is given in his ‘ Manual of Geology ’ 
(1861). The facts from the deep ocean remove all remaining doubt with 
regard to the universality of the movement and the oneness of the system. 
At the same time there does not appear to be any good reason for separat- 
ing from the system the Gulf Stream, as done by Dr. Carpenter. Given
