110 PROCEEDINGS OF REGENTS. 



Professor Langley, and other people have also experimented in this 

 art, but for the most part the results have not yet been brought into 

 shape to be presented to the public. Our own work in this particular 

 investigation we have been obliged to set aside for a while on account 

 of the press of business matters, but it is our intention, as soon as these 

 business details are arranged, to take it up again and present the 

 results to the world. There is a great deal of work to do in this line, 

 and a great many other researches to be taken up, which will keep a 

 large number of investigators busy for a lifetime, and I venture to 

 express the hope that the Smithsonian Institution will continue to 

 encourage the labors of those engaged in these fields.
