ediately following \\)'i~ , when colchicine was taken up as a "fad." 

 Endocrinologists appear to have lost some of their interest in this tool. 

 and this may explain how such important substances as cortisone 

 and ACTH have hardly been tested by colchicine methods. Most 

 of the W'ork was on hormones which stinuilated mitosis; cortisone, 

 on the contrary, appears to have an inhibitory action.-'^ llie useful- 

 ness of colchicine in the study of mitotic inhibitors has not yet been 

 fully understood, and further work will undoubtedly demonstrate
