36 U. S. BUREAU OF FISHERIES 



Dr. R. E. Coker, of the University of North Carolina, collected 

 free-living copepods and identified the more common species. The 

 material collected was retained by Doctor Coker for further study. 



Dr. Bartgis McGlone, of the University of Pennsylvania, studied 

 the effect of varying the hydrogen-ion concentration of sea water 

 upon fertilization and rate of segmentation of the eggs of echino- 

 derms. The results of this work could not be reported when Doctor 

 McGlone left the station, because the necessary microscopical work 

 in determining the results had not been completed. 



Dr. W. C. George, of the University of North Carolina, spent a 

 short time at the station making a histological study of the blood 

 cells of certain species of ascidians. 



W. R. Earle, graduate student of the University of North Carolina, 

 studied and collected material bearing upon the regenerative processes 

 in several forms of hydroids, and he also collected and preserved some 

 material on the earlv embryological stages of Fundulus and the toad- 

 fish. 



J. T. Penny, instructor in histology, Medical School, University 

 of Tennessee, spent a very brief period at the station collecting and 

 fixing specimens of Blanoglossus for study. 



Miss Lorna W. Thigpen, graduate student of the University of 

 Maine, spent several weeks at the station in a general study of inver- 

 tebrate forms, principally with the view of familiarizing herself with 

 the local fauna. 



The Fairport (Iowa) biological laboratory has been mentioned in 

 these pages in connection with the work with fresh-water mussels and 

 in fish culture. T. K. Chamberlain is director. The fish-cultural 

 investigations have been under the immediate direction of H. O. 

 Hesen, superintendent, and H. C. Minch, foreman. As has been 

 stated, Dr. M. M. Ellis, of the University of Missouri, and Dr. N. M. 

 Grier, of Dartmouth College, were employed during the past summer 

 in the mussel investigations. The regular staff was especially active 

 in cooperating with various State and private organizations concerned 

 with the conservation of aquatic resources. 



Conditions at the Key West (Fla.) laboratory did not change dur- 

 ing the year. The lack of adequate laboratory facilities made it 

 impossible to conduct researches at this station, and the activities of 

 the small resident staff were mainly directed toward the maintenance 

 of the grounds and buildings. 



During the year a new fisheries laboratory was established at 

 Seattle, Wash., in temporary quarters kindly provided by the College 

 of Fisheries of the University of Washington. The laboratory was 

 opened under the direction of Dr. W. H. Rich and will be used as a 

 center for the investigation of the fish and fisheries of the Pacific 

 coast. During November and December certain of the salmon inves- 

 tigations were carried on here by Doctor Rich and H. B. Holmes, 

 and it is planned to transfer the investigations on herring and clams 

 to this laboratory in the near future. Such a laboratory has been 

 needed for some time, and its establishment will do much to further 

 the scientific work of the bureau on the Pacific coast.
