Herbert Bolton, pointing out their usual 

 mixed character and lack of relation to the 

 school curriculum and suggesting how they 

 may be made of real value. G. A. Dunlop 

 describes " Drying Plants without Pressure " 

 by the use of fine sand or boxwood sawdust, 

 the latter material preserving many of the 

 natural colors and much of the texture of 

 flowers and leaves. It is pointed out that care 

 should be taken in using sawdust owing to its 

 irritating effect on the mucous membrane of 

 the eyes and air passages. There is an ac- 

 count of the exliibit of " British Grown Trees 

 in the Natural History Museum." Among 

 the many " Notes " is one to the effect that 

 the London and North-Western Eailway is 

 gathering material to be ultimately displayed 

 in a railway museum. 



The Museum News of the Brooklyn Insti- 

 tute for April contains articles on " The Giant 

 Stork, or Jabiru," "Zuni Silver Working," 

 and " Lizards in Human Stomachs." The 

 section devoted to the Children's Museum dis- 

 cusses " Elementary Physics as a Subject for 

 Children's Museum Instruction " and notes 

 the various living animals at the museum. 



A NEW psychological journal, Le revue psy- 

 chologique, has been established at Brussels

THE BIOLOGICAL SOCIETY OF WASHINGTON 



The 442d meeting was held on March 21, 

 1908, with President Stejneger in the chair. 



The first paper was by Professor W. J. 

 Spillman, on " Fixation of Breed Characters 

 in Animals and Plants." He first illustrated 

 the manner of behavior of a character pair 

 (non-albinism and albinism). The character 

 of the population from the second to the tenth 

 generation of the descendants of a Mendelian 

 hybrid was illustrated by lantern slides for 

 different methods of selection. First, with 

 no selection, it was shown that with close
