The work so far accomplished by these col- 



laborators includes : an extensive study of 

 American methylen blues, fuchsins, gentian 

 violets, and eosins for bacteriological purposes; 

 a study of eosin, methylene blue, hasmatoxylin, 

 orange G and safranin for various histological 

 purposes; while work is in progress at present 

 on a number of other stains, including methylen 

 green, Bordeaux red, brilliant green, brilliant 

 cresj'l blue, cresylecht violet, pyi'onin, and acid 

 fuchsin. The results accomplished are so prom- 

 ising that there is reason to believe that the 

 most commonly used stains can be regarded as 

 standardized before the following winter is 

 over. It will then be possible to work out 

 some method of certification of stains which 

 come up to the standards. 



None of this work would have been possible 

 but for the cooperation of such a large numlaer 

 of investigators, who have responded to every 

 call for assistance in a most gratifying way. It 

 was not anticipated at the start that such a 

 large number would be found to take part 

 willingly in an investigation of this sort. The 

 work, of course, has been entirely voluntary. 

 The committee would like, whenever reporting 

 on any stain, to give due credit to all of these 

 collaborators but as such a course is imprac- 

 tical the best plan seems to 'take the present 

 occasion to make their names public and ex- 

 press appreciation for their assistance.

SCIENTIFIC EVENTS 



THE RAMSAY MEMORIAL 



The unveiling of the tablet in Westminster' 

 Abbey in memory of Sir William Ramsay, to 

 which reference ha,s been made in Science, was 

 the last act in connection with the memorial, a 

 history of which is summarized in the London 

 Times. In 1917 an appeal was issued for 

 £100,000 by a committee, under the presidency 

 of 111-. Asquith, and under the chairmanship of 

 the late Lord Reay. At a subsequent date, the 

 Prince of Wales became patron of the fund. 

 The sum collected in cash is £57,645. 



In addition, the fund has been augmented
