Did You Forget? 



The Editoi' of thi.s Bulletin has secured enough new mem- 

 bers, by personal effort, to entitle him to say to each reader : 

 ' * Go thou and do likewise. ' ' If every member of the Academy 

 will accomplish one-eighth as much, per capita, it will very soon 

 be feasible to make the editorials more attractive. It is not a 

 pleasure, but a disagreeable duty, to urge upon you each month 

 to perform what is no more than your due share of the work 

 of upbuilding the Academy of Sciences. Kindly avoid over- 

 exertion in the cause. 



A Worthy Example 



Mr. J. D. Hooker, who has heretofore contributed more than 

 any other person to the funds of the Southern California Acad- 

 emy of Sciences, has generously defrayed the heavy expense of 

 transporting the equipment of the great Observatory which is 

 being constructed on Mt. Wilson under the direction of Pro- 

 fessor Hale and others. We need more members of equivalent 

 calibre.
