It should not be long hefoi'e all scientific 

 journals, in fulfilment of their duty toward 

 their readers, provide carefully prepared pre- 

 liminary abstracts of their scientific articles. 

 There can no longer be any doubt of the value 

 of such abstracts. It remains only to over- 

 come the practical obstacles to the introduc- 

 tion of the new policy. 



In conclusion we desire to express our thanks 

 to the 805 readers whose cooperation gave us 

 the information herewith reported.
