ON BECENl PROGRESS TOWARD THE SOLU- 

 TION OF PROBLEMS IN HYDRO- 

 DYNAMICS. 



In this paper I shall not attempt to give 

 an exhaustive account of the progress which 

 has been made in hydrodynamics of recent 

 years. Such an account, though possibly 

 useful for purposes of reference, would be 

 tedious and unsuitable for reading before 

 an audience. I shall, therefore, try to give 

 some idea of the general lines on which re- 

 search has been carried on, laying stress on 

 the more important discoveries and avoid- 

 ing, as far as possible, mere technical de- 

 tails. 



The choice of the period to be selected is 

 not difficult. In 1846 Professor Stokes pre- 

 sented a report on the condition of hydro- 

 dynamics at that tiqje, and this was con- 

 tinued by Professor Hicks in 1881-1882. 

 Both these papers are printed in the reports 

 of the British Association for the Advance- 

 ment of Science. In the Mathematische 

 Annalen for 1887 Mr. A. E. H. Love gave 

 a summary of our knowledge of Vortex 

 Motion, and Hicks practically carried this 

 to the present day in his presidential ad- 

 dress before Section A of the British Asso- 

 ciation in 1896. Professor Darwin's article 

 on Tides in the Encyclopaedia Britannica 

 carries our knowledge of that subject to 

 1888. Hence I shall take the progress 

 made in the general subject since 1882 ; 

 the work on Tides will be taken from 1 888
