340 Genet’s Memorial. 
on which I wrote something in the preceding number of this 
Journal. I hesitate, however, to be myself his encomiast, 
but I would rather be fecdcnooed to study again my experi- 
mental and mechanical philosophy, than to condemn any por- 
tion of it, much less his departure im part from the Newtonian 
philosophy. Have we not proofs enough in nature, that if 
there are many of its elements under coming agency, there 
are others under a centripetal force? 
We have still much to learn of the contending powers 
which sustain and govern the world ; but if we compare the 
improvements in navigation, which have been made within 
the last thirty years, and which, by means of the steam power 
alone, surpass those of many centnries, we may infer that as 
much remains to be discovered in hydrodynamics, or in the 
laws orerning: the motion, the pressure and the force of other 
fluids. Nor should we be discouraged by the objection 
founded on the a natled impracticability of inventing appro- 
priate and competent machinery. Would the machinery be 
more difficult than that which was necessary to enable the 
Romans to build their colliseum, and the Egyptians to erect 
their great pyramid ? 
First EXPERIMENT, 
Of an erostatic ate on a canal inclined plane and rail- 
rise of one foot to 15 tm 120. 
“This is bee to raise or lower canal boats, whenever 
there is a solution of continuity, from the lower to the higher 
bese Having excavated a basin, plate A, fig. 1, double the 
1 of the canal, at the termination of the water level, @ 
pee daly on an inclined plane B is to be constructed, 
and on the top of the hill, two basins C on the plan of the 
tt dock, riya side drains to discharge the water, without 
ring the r ail-way. Over that dry dock basin, may be 
ructed a spacious frame ene D, with a large cupo- 
Aa the. iGL tes resting on a stone foundation, part of which 
shall be the outside walls of the basin, several feet higher 
than the loaded boats afloat. Under the cupola a pit is to 
be dug for the purpose of a laboratory. 
The moving force of this machinery is to be pinay” the 
AS ve force of an zrostat of a spheroidal form
