THE U. S. FISHERIES BIOLOGICAL STATION 

 AT WOODS BOLE 

 The laboratory of the TJ. S. Fisheries Bio- 

 logical Station at Woods Hole, Mass., was 

 open from June 21 to September 15 during the 

 past summer. P. H. Mitchell, of Brown Uni- 

 versity, was director. Investigators appointed 

 by the Bureau of Fisheries conducted the fol- 

 lowing researches bearing on the economics of 

 the fishing industries: I. A. Field, of Clark 

 College, the anatomy of the circulatory and 

 nervous systems and the embryology of the 

 edible muscle ; C. W. Hahn, of the High School 

 of Commerce, the mode of infection by, and 

 the life history of several parasites of herring, 

 alewives and some other food fishes ; A. Kuntz, 

 of the Washington University Medical School, 

 with L. Eadcliife, of the U. S. Bureau of 

 Fisheries, the identification and study of the 

 embryological and larval stages of twelve 

 species of common fishes; E.> Linton, of Wash- 

 ington and Jefferson College, investigations 

 of various fish parasites with special study of 

 helminth and nematode parasites of butter fish, 

 also a study of the food of winter flounders; 

 P. H. Mitchell and W. W. Browne, of the 

 College of City of New York, nutrition of 

 oysters with special reference to conditions of 

 glycogen formation; S. Morgulis, of the Col- 

 lege of Physicians and Surgeons, the digestive 

 enzymes of Teleosts, the changes in weight and 

 composition of starving lobsters, a critical 

 analysis of Moore's investigations on the metab- 

 olism of marine organisms, and a colorimetric 

 method for approximate oxygen determinations 

 in sea-water ; G. G. Scott, of the College of the 

 City of New York, the oxygen consumption of 

 developing fishes at various stages, the oxygen 

 consumption of 42 marine forms for compari- 

 son of rates of metabolism, the efficiency of 

 various means of aerating aquaria, conditions 

 afFecting the oxygen requirements of fishes, the 



oxygen consumption of regenerating tissues, 

 and the dry method of shipping live fishes; 

 A. Thomas, of Clark University, the toxic 

 effect of heavy metals on fishes; G. F. White, 

 of Clark University, methods of preparing 

 dried dogfish for human food, the distribution 

 of nitrogen in dog fish muscle, the phosphatides 

 of dogfish egg-oil, the collagenous matter of 

 dogfish skulls and of tilefish swim-bladders; 

 W. W. Browne, of the College of the City of 

 New York, the possibilities for fish to act as 

 carriers of pollution bacteria and the time re- 

 quired to rid fish of such bacteria when put in 

 unpolluted water; B. H. Gross, the conditions 

 affecting the occurrence of color in " green 

 oysters " ; K. S. Bice, of Brown University, the 

 behavior of oyster spat under artificial condi- 

 tions, and the methods of ridding oysters of 

 the colored copper-containing compound found 

 in " green oysters." 



Besides the work of employees of the bureau, 

 a number of investigations were conducted by 

 table applicants to whom the facilities of the 

 laboratory were extended. Such researches 

 were as follows: E. P. Bigelow, of the Massa- 

 chusetts Institute of Technology, an exami- 

 nation and study of 2Y species of Crustacea 

 collected by the Albatross during the Philip- 

 pine expedition ; S. R. Clemence, of the Amer- 

 ican Museum of Natural History, a survey of 

 the reptilian and batrachian fauna of the 

 Elizabeth Island; G. A. MacCallum, observa- 

 tions on fish parasites; G. H. Parker, of Har- 

 vard University, a study of reflexes and other 

 nerve reactions of Ccelenterates ; A. C. Eedfield, 

 of Harvard University, the control of chroma- 

 tophores in Fundulus embryos, in flounders 

 and in horned toads; E. A. Eedfield, of Har- 

 vard University, the movements of shell and 

 mantle in Lammellibranchs and the relation 

 of such movements to respiration; I. L. Shaw, 

 studies of diatoms; J. M. Thorrington and 

 F. P. Eeagan, of Princeton University, the 

 development of hybrids with especial reference 

 to the vascular system; H. C. Tracy, of Mar- 

 quette University, the relation of the swim- 

 bladder to the ear and the eighth nerve in 

 clupeidce; G. B. Wislocki, of Johns Hopkins 

 University, the internal secretions of fishes.
