Announcement 



Since the initial appearance of Aquatic Life, 

 in 1915, the publishing world has been passing 

 through an era of difficulties which have 

 caused may delays, effecting even the largest 

 periodicals. It is a custom under such condi- 

 tion to drop numbers, publishing the following 

 number with the designation of the month 

 during which or before which it is mailed to 

 readers. To the present time Aquatic Life 

 has not availed itself of this privilege, hoping 

 that it would be possible to issue numbers 

 sufficiently close together to eventually make 

 up the lost time. This would now seem to be 

 impossible. It has, therefore, been decided 

 to eliminate the numbers for October, Novem- 

 ber and December, ]'.)]'.). thus concluding 

 Volume IV with the September. 1919, num- 

 ber. All subscriptions affected will be ex- 

 tended. Those expiring with the December 

 number, or beyond, will be extended three 

 months; with November, two months; with 

 October, one month. Each subscriber will 

 accordingly receive the actual number of 

 copies for which payment has been made.
