 abundant at San Pedro), by Professor W. E. Ritter, head of 

 department of Zoology of University of California .

Many interesting facts have already been brought to light 

 and when published will form important contributions to Bi- 

 ological literature. 



With the exception of a short trip for taking temperature 

 and soundings the work of the Biological survey was not re- 

 sumed. The work will probably be taken up next year. 



The unqualified success of the two summers' work here has 

 emphasized the desirability of a permanent station at San Pedro. 

 While nothing more definite has been announced than that the 

 work will probably go on next year, it is hoped that more sub- 

 stantial and permanent quarters may be secured. B. M.D.

No settled policy and no fruitful effort towards fraternal relations 

 among isolated scientific societies appears to have had effect prior to 1840, 

 when the American Association of Geologists and Naturalists was or- 

 ganized. Through its influence a distinct advance was made in the popu- 

 larization of Natural Science, resulting, in 1847, in the formation of the 

 American Association for the Advancement of Science. This great body- 

 now has over 3000 members, including the most prominent workers in all
