NOTICE. 



Beginning with Vol. XVI., each article will have a paging of its 

 own ; and the position of an article in a volume ivill be indicated by 

 the number placed at its head. 



It is hoped that this arrangement, ivhich enables us to print paper's 

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

 material than has been possible heretofore. 



All communications relating to this Journal should be addressed to the 

 Director of the College of Science.
