All other students in research courses made satisfactory progress 

 with their work. 



During the summer of 1908 two students received aid to the 

 extent of $140. — from the Humboldt Fund while working: at the 

 Bermuda Station, and two received aid, $35. — , while working at 

 Woods Hole. 



The Bermuda Biological Station for Research was open from 

 June 18 till August 5 inclusive. For two weeks Dr. Rand was in 

 charge; for the remainder of the time, Professor Mark. Seven 

 persons were enrolled and some of the results of studies carried on 

 are already in press; others will appear later in connection with 

 work done in the laboratory in Cambridge. 



There has been installed in the basement a motor generator, 

 which is actuated by the 500-volt direct current already introduced 

 into the aquarium room, and furnishes a direct current of about 

 100 volts suitable for experimental work in which the alternating 

 current could not be employed, and for running projection lanterns 

 already ordered to be installed the coming year. 



Professor Mark received grants from the Carnegie Institution of 

 Washington to the amount of $400. — to aid in investigations 

 already begun. 



The Zoological Club held twenty-eight meetings on the after- 

 noons of Fridays with an average attendance of twenty-two. At 

 these meetings twenty-five original papers were presented and a 

 number of others were reviewed. The subjects to be presented 

 or discussed were usually announced in the University Gazette.
