THE MESSAGE OF SCIENCE.i 



It is just forty years ago, at the York 

 Meeting in 1881, that a committee was ap- 

 pointed " to arrange for a conference of dele- 

 gates from scientific societies to be held at 

 the annual meetings of the British Associa- 

 tion, with a view to promote the interests of 

 the societies represented by inducing them 

 to undertake definite systematic work on a 

 uniform plan." The association had been 

 in existence for fifty years before it thus be- 

 came a bond of union between local scienti- 

 fic societies in order to secure united action 

 with regard to common interests. Through- 

 out the whole period of ninety years it has 

 been concerned with the advancement and 

 diffusion of natural knowledge and its ap- 

 plications. The addresses and papers read 

 before the various sections have dealt with 

 new observations and developments of scien- 

 tific interest or practical value; and, as in 

 scientific and technical societies generally, 

 questions of professional status and emolu- 

 ment have rarely been discussed. The port 

 of science — whether pure or applied — is free, 

 and a modest yawl can find a bea-th in it as 

 readily as a splendid merchantman, provided 

 that it has a cargo to discharge. Neither the 

 turmoil of war nor the welter of social unrest 

 has prevented explorers of uncharted seas 

 from crossing the bar and bringing their 

 argosies to the quayside, where fruits and 

 seeds, rich ores and precious stones have been 

 piled in profusion for the creation of wealth, 

 the comforts of life, or the purpose of death, 

 according as they are selected and used. 



All that these pioneers of science have 

 asked for is for vessels to be chartered to en- 

 able them to make voyages of discovery to

 cieties, given at the Edinburgh meeting of the Brit- 

 ish Association for the Advancement of Science.
