M. Chapman entitled ' The Bird Rocks of 

 theGulf of St. Lawrence.' He was followed 

 by Dr. Thomas S. Roberts, who gave an 

 exhibition of lantern slides of birds, birds' 

 nests and nesting haunts from photographs 

 taken by himself in Minnesota. Other 

 slides were shown by Messrs. William 

 Dntcher and William L. Baily. 



In the evening the Union met in the 

 Assembly Hall of the Cosmos Club, by 

 courtesy of that Club. Here three papers 

 were read, viz.: ' On the Nesting Habits of 

 the Brown Pelican on Pelican Island, 

 Florida,' by Frank M. Chapman ; ' Chapter 

 in the Life of the Canada Jaj',' by Oscar 

 Bird Warren ; and ' Clarke's Crows and 

 Oregon Jays on* Mt. Hood,' by Florence A. 

 Merriam. All of the slides exhibited were 

 eifective, showing care and patience in ob- 

 taining the negatives. 



Mr. Witmer Stone, Chairman of the Com- 

 mittee on Protection of North American 

 Birds, read a most interesting report on 

 the work done during the past year. The 

 repoi't will be published in The Auk, and re- 

 printed as a separate pamphlet, to be sold 

 at a very low price. 



The graphophone demonstration of a 

 brown thrasher's song by Dr. Sylvester D. 

 Judd was a new and unique feature of the 

 Congress. Dr. Judd's experiments were 

 made with a cage bird, but the results ob- 

 tained were enough to show that great 

 possibilities in this field may be looked for 

 in the future. 



Following is a list of the papers read at 

 the session, in addition to those already 

 mentioned : 



' Among the Birds in Nevada,' Harry C. Oberholser.

 beicickii Group,' Harry C. Oberholser.

CUBBENT NOTES ON ANTHBOPOLOGY. 

 THE MAP OF OUAUHTLANZINCO. 



XJjSTDEE the above name Mexican archae- 

 ologists have described a series of paintings 

 about thirty-three in number, preserved in 

 the native town bearing the appellation. 

 They were drawn and colored some dec- 

 ades after the Conquest, in order to pre- 

 serve the memory of that portion of it in 

 which the town was engaged. In the 

 present century a new copy was made, as 

 the first canvasses were falling to pieces.* 

 Inscriptions in Nahuatl and Spanish were 

 added, to explain the various scenes de- 

 picted by the native artists. 



Professor Frederick Starr visited the 

 hamlet in 1895 and again last January, 

 and obtained photographs of all the pictures 

 and a copy of the Spanish explanations. 

 These he has published in an instructive 

 monograph, issued from the press of the 

 University of Chicago. It will be read with 

 pleasure by those interested in the archse- 

 ology of Mexico (' The Mapa de Cuauh- 

 tlantzinco or C&dice Campos ').
