continued by the receipt of the current maps of the United States 

 Weather Bureau. 



The records and collections of the New England Meteorological 

 Society are also kept in the Laboratory storeroom. Mr. J. Warren 

 Smith, lately of the United States Signal Service, and now of the 

 United States Weather Bureau, acting as assistant to the Society 

 in its capacity as a local weather service for New England, has 

 his office here. 



During the winter, Mr. S. Ward Loper, of the United States 

 Geological Survey, classified the fossil fish collected under the 

 direction of Professor Davis from the Triassic formation of the 

 Connecticut valley, and now temporarily placed in the Laboratory 

 storeroom. An account of the results of this study has been 

 published, as stated below. 



The publications of Professor Davis during the year are as 

 follows : —

 year in original investigation.
