Since to most of us the millilambert conveys 

 no very definite meaning in, terms of a familiar 

 visual sensation, I may add that according to 

 the measurements of Coblentz a tungsten fila- 

 ment at 2000° C, which is not far from the 

 temperature of our ordinary incandescent 

 lamps of the vacuum type, has a brightness of 

 630,000 miUilamherts. 



Since our various fluorescent substances vary 

 in color it should be further stated that the 

 brightness in each case is such that the- inten- 

 sity of the maximum region in the fluorescent 

 band equals the brightness of the correspond- 

 ing region in the spectrum of a neutral matte 

 surface of the specified numljer of milli- 

 lamberts. 



In general, according to these measurements 

 our known luminescent materials are of the 

 order of a few millionths in brightness com- 

 pared with an illuminant such as the ordinary 

 electric lamp.

THE AMERICAN SOCIETY OF 

 ZOOLOGISTS 



The American Society of Zoologists held its 

 nineteenth annual meeting at the University of 

 Toronto in conjunction with Section F of the 

 American Association and in association with 

 other biological societies on December 28, 29 and 

 30, 1921. President C. A. Kofold and Vice- 

 president A. L. Treadwell presided at the various 

 sessions. 



William Bateson, director of the John Inues 

 Horticultural Institution, Merton Park, Surrey, 

 England, was elected honorary fellow of the 

 society. 



The following were elected to membership: 



Edward F. Adolph, University of Pittsburgh; 

 Charles P. Alexander, University of Illinois; 

 William K. Allen, University of Akron; Horace 

 B. Baker, University of Pennsylvania; Frank N. 

 Blanchard, University of Michigan; Joseph H. 

 Bodine, University of Pennsylvania; Eobert H. 



Bowen, Columbia University; Alfred E. Cameron, 

 University of Saskatchewan; William H. Cole, 

 Lake Forest College; Mary E. CoUett, University 

 of Buffalo; Eheinart P. Cowles, Johns Hopkins 

 University; Alden B. Dawson, Loyola University 

 Medical School; Hoyt S. Hopkins, Baylor Medical 

 College; Carl L. Hubbs, University of Michigan; 

 George W. Hunter, Knox College; Donald E. 

 Lancefield, University of Oregon; James W. 

 MacArthur, University of Toronto; Eobert S. 

 McEwen, Oberlin College; Peter W. Okelberg, 

 University of Michigan; Charles L. Parmenter, 

 University of Pennsylvania; Mary E. Pinney, 

 Lake Erie College; Franklin P. Reagan, Uni- 

 versity of California; Eobert C. Rhodes, Emory 

 University; Franz Schrader, Bryn Mawr College; 

 Gotthold Steiner, University of Berne; Horace W. 

 Stunkard, New York University; Tage Ellinger, 

 University of Illinois; Lewis H. Weed, Johns 

 Hopkins University; Alvalyn E. Woodward, Am- 

 herst College; Benjamin P. Young, Cornell Uni- 

 versity; Hachiro Yuasa, University of Illinois. 



After the election the membership roll of the 

 society contained 357 names of members in good 

 standing. 



The report of the treasurer showed a probable 

 balance for January 1, 1922, of $808.20, a loss 

 for the year of $81.71, although there are fewer 

 members in arrears than at any time in the last 

 four years. The attention of the society was 

 called to the fact that the present plan of oper- 

 ating on a basis of fifty cents per member per 

 year must in time deplete the accumulated sur- 

 plus of the society. 



The constitution and by-laws were amended +o 

 , permit the separation of the office of secretary- 

 treasurer. 



The nominating committee, composed of M. F. 

 Guyer, S. J. Holmes and J. H. Gerould, reported 

 the following nominations : 



President— H. H. Wilder. 



Vice-President — B. M. Allen.
