SCIENCE 



TENTH YEAR. 



The use of Science by scientific men has increased in the past 

 few months as never before. More than tWO hundred of the 



leading scientific men and women of America have 



agreed to contribute to the paper during the coming year ; and, 

 as others are constantly joining in this move, to make the paper more 

 valuable than ever, it cannot be long before there will be a body of 



five hundred competent users of this weekly medium 



of scientific discussion. It is our aim to place the paper in the 

 hands of all competent persons who will avail themselves of this oppor- 

 tunity to make Science a better representative of American scientific 

 work than ever in the past.
