 Summary 



INTRODUCTION 

 In a paper which appeared some years ago the results of an 

 experimental investigation into the flow of marble were presented.^ 

 As this line of investigation seemed to be one which promised to 

 yield additional results of interest if further developed, a grant was 

 made to the present writer by the Carnegie Institution of Washington 

 for the continuance of this work. A more complete equipment for
