332 THE AUXETIC ACTION OF GLOBIN 



globin is we do not know, but possibly it is allied in 

 some way to the molecules of kreatin and xanthin. It 

 should also be remembered that we do not know what 

 the substance is in the azur dye which induces divisions. 

 We think that they will not be difficult to isolate; but 

 we ourselves do not feel competent to undertake 

 chemical analyses of this nature.
