 mological Commission Reports, Volumes 2 and 3, 1878-82. 



Through the kindness of their authors we have received the 

 following books: 



B. M. Patton, "Laboratory Directions in Embryology," 5 



volumes. 



E. G. Conklin, "Direction of Human Evolution." 

 G. H. Parker, "Smell, Taste, and Allied Senses in Vertebrates." 

 W. C. Curtis, "Science and Human Affairs." 

 L. L. Woodruff, "Foundations of Biology." 



B. H. Grave, "Birds of Wyoming."

H. C. van der Heyde, "Physiology, Digestion, Respiration, and 

 Excretion in the Echinoderms."
