 — Presidential address at St. Louis meeting of American Association for the Advancement of 

 Science, Dec, 1919. The recent tendencies which seem to indicate future development are: 



(1) dealing with problems that are fundamental in connection with some important practise, 



(2) increasing realization that problems are synthetic, and (3) that structures are not static. 

 There is no sharp division between pure and applied science. The investigator needs a broad 

 training in order that he may be able to make use of the work of specialists in the various 

 branches. Co-operation will play an important part; also experimental control in investiga- 

 tional work. — [See also next following Entry, 1511.] — 0. A. Stevens. 



1511. Coulter, J. M. The evolution of botanical research. Science 51: 1-8. Jan., 1920. 

 — In this address certain evolutionary tendencies in the science of botany are pointed out. 

 The phase of segregation among botanists has passed. One of the growing tendencies is to 

 attack problems that are fundamental in connection with important practises, as, for example, 

 the problems which underlie agriculture. Another tendency is increasing realization that 

 botanical problems are synthetic. The morphologist, physiologist, ecologist, now realize 

 that the facts possessed by one have a close relation to the successful work of the other. Still 

 another tendency is the growing recognition of the fact that structures are not static. One 

 must learn to distinguish between those structures that are relatively fixed and those that 

 are variables. The conception of rigidity of structures is well illustrated by the early work of 

 cytologists and that dealing with genetics. Experience has begun to enlarge the prospective 

 of workers in these fields. It will be necessary for the successful botanists of the future to 

 have a broader training than heretofore; to cooperate in research; to subject their work to 

 rigid experimental control before conclusions are reached. [See also next preceding Entry,
