ON THE SPECIAL PROBLEMS OF DYNAMICS. 245 
Cournot, “‘ Mémoire sur le Mouvement &c.” (1830 and 1832). 
Puiseux, ‘‘ Du Mouvement &c.” (1848). 
To which: several others might doubtless be added; but the problems are so 
difficult, that the solutions cannot, it is probable, be obtained in any very 
complete form. 
In conclusion, I can only regret that, notwithstanding the time which has 
elapsed since the present Report was undertaken, it is still—both as regards 
the omission of memoirs and works which should have been noticed, and the 
merely cursory examination of some of those which are mentioned—far from 
being as complete as I should have wished to make it. To have reproduced, 
to any much greater extent than has been done, the various mathematical 
inyestigations, would not have been proper, nor indeed practicable; at the 
same time, more especially as regards the subjects treated of in the second 
part of this Report, or say the kinematics and dynamics of a solid body, such 
a reproduction, incorporating and to some extent harmonizing the original 
researches, but without ignoring the points of view and methods of investi- 
gation of the several authors, would be a work which would well repay the 
labour of its accomplishment, é
