190 ^ CENTURY OF PROGRESS IN THE NATURAL SCIENCES 



With the expanding use of algae as experimental material we may look for- 

 ward to an increasing awareness among biologists in general of the need for 

 precise identity of the forms under investigation. It may be anticipated there- 

 fore that the preservation of voucher collections of published material will be- 

 come standard practice and that the maintenance and welfare of such reposi- 

 tories as herbaria, museums, and living culture collections will be the concern 

 and the accepted responsibility, not only of the taxonomist and morphologist, 

 but of all biologists.
