502 Mr Phillips’ Method of PropelUiig Vessels. 
Tile separation of Iron from Uranium cannot be accomplish- 
ed by this process, as this metal possesses a property analogous 
to that which forms the subject of the paper. It may be done, 
however, by inverting the process. A mixed solution of iron 
and uranium being deoxidised, by a current of sulphuretted 
liydrogen, and then treated with an earthy carbonate, the iron 
passes in solution, while the uranium separates. — P. 299. 
14. Account (yf Mr Phillips'’ Method Propelling Vessels. 
Mr Phillips is, we believe, the first person who has proposed 
to place the paddle-wheels of steam-boats in a horizontal position. 
The greater part of this horizontal wheel is inclosed between 
decks. Each horizontal wheel carries eight vertical paddles, and 
each paddle has a piece x>f machinery connected with it, by which 
iti s lowered into the water when it emerges from between decks, 
and, after giving its stroke, it is again elevated. The succeed- 
ing paddle is lowered in a similar manner, performs its stroke, 
and ascends like the one which preceded it. Mr Phillips con- 
ceives that vessels may be propelled in this manner in high or 
rolling seas with greater effect, than by the ordinary contrivances. 
The idea of using a horizontal wheel, is, so far as we know, 
new and ingenious ; but though such a contrivance, with paddles 
capable of being lowered and elevated, might answer in very 
slow motions, we fear that it will be found in practice, when a 
very rapid revolution of the wheel is absolutely necessary, to be 
not only inexpedient, but to be extremely liable to go out of 
order. Mr Phillips has taken out a patent for the invention, 
which he declares to consist in placing the paddle-wheels hori- 
zontally.

Propelling Vessels. 
The principal object of this invention is to convert the steam- 
boat into an ordinary vessel, to be driven by canvas in stormy 
weather. In order to effect this, two horizontal channels are 
made to extend through the whole length of the vessel, with 
entrance and exit apertures for the water, which reaches nearly 
to their top. Two or more pair of paddle-wheels are mounted,
