PUBLISHER'S NOTICE 



The price of the paper on which SCIENCE 

 is printed has increased to i6 cents a pound; 

 five years ago it was ^/% cents. Within this 

 period the cost of composition and press work 

 has about doubled; the charges for binding 

 and mailing have increased even more. 



The subscription price of NATURE in Eng- 

 land is now $10.50. It has been possible to 

 supply SCIENCE at the present rates only on 

 account of the advertisements. But advertis- 

 ing contracts are usually for a year, and the 

 increases in the cost of printing and paper 

 during 1920 have been such that the charges 

 for most of the advertisements in the journal 

 are now less than the actual cost of printing 

 them. The rates have been increased for new 

 contracts, but with continually increasing 

 prices they now only about meet the cost of 

 printing, except when preferred positions are 

 purchased. 



iScientific men assist SCIENCE by ordering 



apparatus, supplies, etc., for themselves and 

 their laboratories from the firms that advertise 

 in the journal. This they can do to advantage, 

 for the firms are the best in the United States. 

 It is also of help when those who make pur- 

 chases owing to an advertisement in SCIENCE 

 state this fact in their correspondence. All 

 scientific men would probably wish their books 

 to be advertised where they are brought to the 

 attention of those most interested, and it is of 

 assistance when this fact is stated to pub- 

 lishers. 



The maintenance and improvement of 

 SCIENCE are of importance for the advance- 

 ment of science. Those men of science who 

 will see that the journal is in all libraries and 

 laboratories where it would be of service and 

 who will read and use the advertising pages 

 will assist the journal, while at the same time 

 benefiting themselves and contributing to the 

 conditions favoring scientific research.
