the tubes and made the tests during the summer of 1900. They 

 reported that the resistance of a wire was increased by removing 

 the amalgamated gases. In one experiment the resistance of the 

 wire forming a spiral terminal in an X-light tube was # 068 of an 

 ohm before and "080 after. The instruments for making the 

 experiments were not of a high grade. On this account the 

 results were not reported, as I hoped to repeat the experiments 

 with better apparatus and with terminals made of all the common 

 metals. As this opportunity has not come, I now report the 

 experiments that some one better equipped may extend them.

1. American Association. — The fiftieth annual meeting of the 

 American Association for the Advancement of Science was held 

 at Denver, Colorado, during the week beginning August 24th. 

 The President of the meeting was Professor Charles S. Minot of 

 Cambridge. The attendance was larger than might have been 

 anticipated considering the distance of Denver from Eastern 

 centers, the registration reaching 311; nearly one-third of those 

 in attendance came from the Atlantic coast. The interest taken 

 by the citizens in the proceedings and their efforts for the enter- 

 tainment of the guests contributed essentially to the success of 

 the meeting. About 220 papers were presented for reading at 

 the sessions of the Association and those of the affiliated societies, 

 which were also well attended. The address of the retiring 

 President, Professor R. S. Woodward, was delivered on the 

 evening of August 27 on the subject "The Progress of Science." 

 The address is printed in full in the issue of /Science for August 

 30. The following numbers of the same journal, which is now 

 the official organ of the Association, contain a detailed account 

 of the Denver meeting with the addresses of the Vice Presidents 

 before the several sections.
