NOTE 



Instead of raising the price of membership, an,d in order to meet the require- 

 ments of the War Industries Board, and also because of the drafting of the 

 whole Editorial Staff the July, August and September numbers have been 

 dropped out for 1918. Vol. IX will contain only 8 instead of 12 numbers.
