The dates for sessions of the American 

 Physiological Society in Baltimore are Decem- 

 ber 26-29. The council meets in the evening, 

 December 26, and the scientific sessions begin 

 in the morning, December 27, and continue 

 through the morning of December 29. The 

 session in Washington in connection with Sec- 

 tion K is planned for the afternoon of Decem- 

 ber 29. Arrangements are being made for a 

 symposium on Acapnia and Shock for this 

 joint session. The headquarters in Baltimore 

 ■will he at the Hotel Rennert, corner of Liberty 

 and Saratoga streets. Arrangements have been 

 made by which members of the three societies 

 (Physiological, Biochemical and Pharmacolog- 

 ical) meeting in Baltimore may dine together 

 at the headquarters on Wednesday and Thurs- 

 day evenings, and it is proposed that on both 

 evenings the dinner shall terminate in an in- 

 formal smoker. The scientific sessions of the 

 society will be held in the physiological build- 

 ing of the Johns Hopkins Medical School.

 sions have been received from the following

 side over the meeting. The program includes 

 a conference on Friday on Ten Years' Progress 

 in Vertebrate Paleontology with papers as fol- 

 lows: 



Wm. B. Scott: South American Mammals. 



W. D. Matthew: African Mammals. 



O. A. Peterson: Artiodactyla. 



J. W. Gidley: Perissodactyla. 



W. D. Matthew: Carnivora and Eodentia. 



W. K. Gregory: Primates, Marsupials and In- 

 sectivores. 



F. W. True: Marine Mammals. 



E. C. Case: Paleozoic Eeptiles and Amphibia — 

 a Comparison of Old and New World Forms. 



W. J. Holland: Pre-cretaeeous Dinosaurs. 



E. S. Lull : Cretaceous Dinosaurs. 



O. P. Hay: Chelonia. 



J. C. Merriam: Marine Eeptiles. 



Bashford Dean: Paleozoic Fishes. 



C. E. Eastman: Mesozoic and Cenozoie Fishes. 



H. F. Osborn: Correlation and Paleogeography. 



S. W. Williston: Evolutionary Evidence. 



W. J. Sinclair: Contributions to Geologic The- 

 ory and Method. 



Each of these papers is to discuss the follow- 

 ing points : (a) status of our actual knowledge, 

 and principal material in different museums 

 which has been brought together in recent 

 years : (6) theories accepted and rejected in 

 recent years; (c) hypotheses on trial; (d) im- 

 portant investigations and explorations which 

 should be made. 



We are requested by the chief of the Weather 

 Bureau to announce that in connection with 

 the Washington meeting of the American As- 

 sociation for the Advancement of Science an 

 informal gathering of persons interested in 

 meteorology and kindred subjects will be held 

 at the Weather Bureau buildings, 24th and M 

 streets, N. W., Thursday afternoon, December 

 28, from 5 to Y p.m. The location is easy of 

 access via the Pennsylvania Avenue car-line, 

 by which many members of the association will 

 be returning from the cavalry drill at Fort 

 Myer, the same day. The drill is from 3 to 

 4:30 P.M. The proposed gathering will be 

 analogous in character and purpose to the 

 " meteorological luncheon " of the British As- 

 sociation, and its promoters hope that a meet- 

 ing of this kind may become an annual event. 

 A series of five-minute talks will be given by 

 leading men of science on the general subject, 

 " The Relation of Meteorology to other Sci- 

 ences." The scope of the discussion will be 

 broad enough to interest every one, and it is 

 hoped that the attendance may be general on 

 the part of members of the association and
