At the Friday session a resolution was 

 adopted, that it was the sense of the section of 

 paleozoology, that the time was ripe for the 

 organization of a Society of American Paleon- 

 tologists, to include vertebrate and inverte- 

 brate paleozoology and paleobotany. A com- 

 mittee was appointed, with Professor H. F. 

 Osborn as chairman, to confer with the officers 

 of the Society of Vertebrate Paleontologists 

 with a view to disbanding that society, or 

 merging it with the larger body, and to cor- 

 respond with all teachcvs of, and workers in, 

 paleontology in North America, with the view 

 to the formation of the new society. 



Before the final adjournment of the section 

 on Friday, Professor Osborn, in behalf of the 

 local committee, and of the American members 

 of the section, expressed great pleasure in 

 being able to welcome the distinguished for- 

 eign paleontologists present, and assured them 

 that American paleontologists greatly appre- 

 ciated their efforts towards making this meet- 

 ing such a success. Professor Steinmann, in 

 reply, expressed the appreciation on the part 

 of the foreign delegates, of the welcome given 

 them, and further expressed the hope that this 

 meeting might be the first of many others for 

 the benefit of all concerned.
