1912] Ritter: The Marine Biological Station of San Diego — 148 
would the list of those whose labors have contributed most to 
the institutional upbuilding and operations of the station be 
in any wise complete without reference to the vicarious activities, 
official and scientific, of Mrs. William E. Ritter, wife of the 
scientific director. 
Acknowledgment is also heartily made of the uniform cour- 
tesy and in several instances substantial help and encouragement 
given the station by persons acting in official capacity for the 
city of San Diego. 
Finally, Miss Ellen B. Seripps and Mr. E. W. Seripps, the 
main financial supporters of the station, remain to be mentioned 
though only in general terms in this catalogue of acknowledg- 
ments. What these two have done in a monetary way is shown 
under other captions. The fact of fundamental importance to 
be brought out here is that whatever has been accomplished has 
been by earnest, thoughtful, sympathetic codperation between 
those, on the one side, possessed of technical scientific knowledge 
and experience but no material resources; and on the other side, 
those possessed of large material resources but little of the tech- 
nical knowledge and experience requisite for such an enterprise, 
the common meeting ground of the two parties being great faith 
in the efficacy of natural knowledge toward the highest good of 
mankind. By codperation I do not mean that one party fur- 
nishes merely the money and the other party merely the technical 
experience. Such a conception is altogether too small for the 
sort of codperation that is being practiced here. The truth is 
that one party furnishes the money primarily, and secondarily 
solicitude, sympathy and keen intelligence in the general devel- 
opment of the institution, while the other party furnishes tech- 
nical knowledge and experience primarily, and secondarily 
thoughtfulness, care, and judgment in the business management. 
Thus all along the line there is recognition both by givers 
and doers that in such an enterprise no one, however much 
material wealth or personal ability he may have, can accomplish 
anything alone. Suecess depends not only on individual but 
on communal efforts.
