To the Readers of SCIEivCE: 



During the past year it has been found possible to enlist the interest of 

 scientific workers in the success of Scietice to such an extent that more than eight 

 hundred have promised contributions during the coming twelve months. Not 

 only are contributions of merit coming in ever increasing numbers from American 

 scientific men and women, but we are now securing our first contributions, in any 

 quantity, from abroad. 



We know that this development in the usefulness of Science is appreciated, 

 not only from the many kind letters received, which are always inspiring and 

 which we wish our friends would mark as at our disposal for publication, but 

 from a marked increase in the number of new subscribers. 



Science owes its existence to the munificence of two gentlemen, whose names 

 we do not feel at liberty to publish, who contributed very nearly $100,000 toward 

 the support of the paper in its early years. There is no longer need of such 

 liberal subsidizing, but we do need cash subscriptions from all who feel at all in- 

 terested in a weekly journal of science in America. 



There is no question that scientists are cosmopolites and that a journal is the 

 more useful to them the more it is international in its character. As the result of 

 our efforts to develop the use of Science abroad, we have recently published 

 articles from V. Ball, Dublin ; Edward T. Dixon, Cambridge, England ; A. H. 

 Keane, London ; David MacRitchie, Edinburgh ; Edward Seler, Berlin ; Isaac 

 Taylor, York ; G. D. Liveing, Cambridge, England ; the Marquis de Nardaillac, 

 Paris ; Miss Agnes Crane, Brighton, England ; E. Trouessart, Paris ; J. Edmund 

 Clark, York ; and have in hand for early publication a number of papers from 

 prominent European scientific men. 



To develop this international feature of the paper an enlargement to twice 

 its present size will be necessary, and an increase of the price to six dollars. 



If we can secure a sufficient increase in the number of subscribers we can 

 promptly enlarge and improve Science still further, but cannot without, as in the 

 past the work, as will be seen, has been largely a labor of love. Within the 

 acquaintance of each of our readers there must be some one sufficiently interested 

 in the development of what we hope is a valuable means of scientific discussion 

 to subscribe six dollars, and we urge each and all our friends to do what they 

 can to help. If the number of new subscribers is as large as we hope, one-half of 

 the enlarged Science would be printed and published in London to facilitate 

 promptness of publication. 



Form of Subscription. 



N. D. C. Hodges, 874 Broadway, New York : 



Enclosed is check (money order, or whatever it may be) for six dollars, for 

 which enter me as a subscriber to Science for one year and thirty-seven weeks, it 

 being understood, however, that if the number of new subscribers received justi- 

 fies the enlargement of the paper to twice its present size, the price being raised 

 to six dollars per year, the term of ray subscription shall be curtailed //-t? rata for 

 the unexpired term.
