The edition of the Annals has been increased from 1000 to 

 1250, and during the year the mailing list has been extensively 

 revised and straightened out. There is necessarily some delay 

 in the issuing of the papers, owing to the necessary slowness 

 in reading the proof of certain articles ; some changes to be 

 made in the mode of publication with intent toward insuring 

 regular time of appearance of the parts of the Annals is abso- 

 lutely necessary.
