THE GALTON AND MENDEL CENTENARY 



The year 1922 is notable as the centenary of the births of both FRANCIS 

 GALTON and GREGOR MENDEL. An international celebration of the centenary 

 of the birth of MENDEL is to be held in Briinn, Czechoslovakia, iu September, 

 and a portion of the scientific programs at the corning Convocation- Week 

 meetings in Boston, U. S. A., will be arranged as a memorial to GALTON and 

 MENDEL. 



The coincidence of these two centenaries deserves to be signalized by the 

 establishment of a permanent Memorial and the EDITORIAL BOARD OF GE- 

 NETICS proposes for this purpose to raise by popular subscription a "GALTON 

 AND MENDEL MEMORIAL FUND," the principal of which shall remain intact in 

 perpetuity, the inco'me only to be devoted to defraying the expense of occa- 

 sional colored plates or other expensive types of engraving, as needed, and 

 also to meeting a part of the heavy cost of publishing tabular matter so 

 essential in a technical genetical journal. 



In asking all subscribers to contribute liberally to this FUND, the two fol- 

 lowing considerations may be pointed out: (a) GENETICS is not published to 

 make a profit for any one, and the proceeds of the MEMORIAL FUND will all 

 go back to the subscribers in the enhanced value of the journal; (b) the only 

 other technical genetical journal published in the English language charges 

 $1 7 . 00 for 600 pages, while GENETICS charges only $6 . 00. Each subscriber to 

 GENETICS can well afford to contribute some small multiple of the difference in 

 subscription price between these two journals, since in this way can be best 

 assured that the low subscription price of GENETICS will be continued, while 

 its facilities for adequately meeting the publication needs of genetical investi- 

 gators will be materially increased. 



Subscribers are kindly requested to consider this a direct personal appeal 

 to each, individually, to send as generous contribution as possible, without 

 awaiting a special request by letter, thus saving a portion of the cost of direct 

 correspondence.
