REPORT ON HYDROSTATICS AND HYDRODYNAMICS. 151 



plete as it is, may suffice to show that this department of science 

 is in an extremely imperfect state. Possibly it may on that ac- 

 count be the more likely to receive improvements ; and I am 

 disposed to think that such will be the case. But these im- 

 provements, I expect, will be available not so much in practical 

 applications, as in reference to the great physical questions of 

 light, heat and electricity, which have been so long the subjects 

 of experiment, and the theories of which require to be perfected. 

 For this purpose a more complete knowledge of the analytical 

 calculation proper for the treatment of fluids in motion may be 

 of great utility.
