seventeen private laboratories for investigators. The buildings, of 

 wood, are both two stories high, well lighted and amply supplied with 

 running water, both salt and fresh. According to the directors, about 

 seventy-five investigators have made use of the laboratory since its 

 foundation and something like six hundred and fifty students of various 

 grades have received instruction. Eegular class instruction is given each 

 summer by university professors from the departments of zoology, bot- 

 any and physiology. Although the buildings are not formally open 

 during the rest of the year, investigators are usually able by special 

 arrangement to get the use of the laboratories at almost any time. 



The laboratory was a gift of Timothy Hopkins, of Menlo Park, 

 Calif., but is dependent on the university for maintenance funds, 

 library, and equipment. Students who receive class instruction pay 

 fees, the money derived from this source being applied to the running 

 expenses of the institution. 



Professors C. H. Gilbert and 0. P. Jenkins, of the departments of 

 zoology and physiology, respectively, have been from the beginning 

 joint directors of the laborator}^, but the courses of instruction have 

 been mostly given in later years by the younger men of the university. 

 Professors Harold Heath, P. M. McFarland and W. B. Price having 

 been especially faithful and eSicient in this capacity. 



Pacific Grove is an exceedingly advantageous location for a marine 

 station, particularly one with the aims which the Hopkins laboratory 

 set for itself; namely, those of providing facilities for investigations 

 on littoral animals and plants and those inhabiting the bottom in rela- 

 tively shallow waters ; and of giving instruction to elementary students. 



So far as the writer's somewhat extensive observations on the Pacific 

 littoral of Korth America has gone, no other point on the whole coast, 

 with the possible exception of Yakutat Bay in southeastern Alaska, has 

 a rocky shore fauna and flora of greater luxuriance, whether as to 

 individuals or species, than has the southern shore of Monterey Bay. 

 This richness of life, taken along with the accessibility of the locality 

 from a populous center, and the all-year-round congeniality of the 

 climate, has made the Hopkins laboratory an important factor in the 

 promotion of biological science in this part of the country. It is greatly 

 to be hoped that at no distant day the laboratory will become possessed 

 of sufficient funds to enable it to be fully prepared to receive investi- 

 gators and students at any time of the year, and not be obliged to re- 

 strict its activities so largely to the summer months. 



The Herzstein laboratory, also at Pacific Grove, is quite different in 

 aim and scope of activities from the Hopkins. It was a gift to the 

 department of physiology of the University of California by Dr. Morris 

 Herzstein, of San Francisco, the primary purpose of which was to pro- 

 vide a sea-side working place where Professor Jacques Loeb could 

 prosecute certain of his investigations.
