Beginning with Vol. XVI., each article has a paging of its oion ; 

 and the position of an article in a volume is indicated by the number

It is hoped that this arrangement, which enables us to print papers 

 independently of one another, loill ensure a more rapid publication of the 

 material than has been possible heretofoi'e. 



All communications relating to this Journal should be addressed to the 

 Director of the College of Science.
