 on physiology is $9.20. Many physiologists 

 will probably wish also the volume on general 

 biology, the annual price of which is $2.45. 

 The Smithsonian Institution acts as the rep- 

 resentative of the central bureau in the United 

 States, and receives subscriptions. 



The International Catalogue is the one 

 catalogue of scientific literature whose per- 

 manence can be relied upon. Its first issue 

 is full of promise. Its ultimate completeness 

 will be hastened by the cordial cooperation of 

 those whose labors it is intended to lighten.

THE WASHINGTON MEETING OF THE AMERICAN 

 PHYSICAL SOCIETY. 



The spring meeting of the American Phys- 

 ical Society was held at Washington, D. C, 

 April 22 and 23, at the invitation of the Wash- 

 ington Philosophical Society. Two sessions 

 for the reading of papers and an evening lec- 

 ture by Dr. Alexander Graham Bell on his 

 famous tetrahedron kites were all held at the 

 rooms of the Cosmos Club. These and other 

 courtesies of the Cosmos Club were much ap- 

 preciated by the society. 



On Friday evening a considerable number 

 of members of the society dined together at 

 the Hotel Barton, and on Saturday, at the 

 close of the morning session, the Philosophical 

 Society entertained all members of the Phys- 

 ical Society who had been attending the ses- 

 sion at luncheon at the same hotel. In the 

 afternoon a visit was made to the new build- 

 ings of the Bureau of Standards, which are 

 located near Connecticut Avenue in the north- 

 western suburbs of the city, about four miles 

 from the White House. 



There was a good attendance at the meet- 

 ing and an tmusually full list of papers was 

 presented. All the papers in the following 

 list were presented by the author or authors, 

 excepting those by S. J. Barnett and A. A. 

 Bacon, the authors being absent, and E. B. 

 Eosa and M. G. Lloyd, because the hour for 

 luncheon had arrived.
