NOTE 



Instead of raising the price of membership, and 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 and 1919. Vol. IX contains only 8 instead of 12 numbers, 

 as will also Vol. X.

 and September by the American Genetic Association (formerly called the American 

 Breeders' Association) for the benefit of its members. Canadian members who desire
