MARINE BIOLOGICAL STATION AT PORT ERIN. 33 



students and investigators worked at the Station mainly 

 during the months March to September. The visitors to the 

 Aquarium and Museum were very numerous, about 27.900 

 being recorded. In this side of the business there are quite 

 remarkable opportunities f or public instruction and propaganda. 

 Exhibits and synopses illustrating the local sea-fishing industry 

 and natural history might be further developed while short 

 evening lantern lectures during the holiday season might deal 

 with such matters as the " Fish as Food " campaigns of the 

 pre-war period, health subjects, etc. It is hoped that, after 

 the present period of material development, something may 

 be done in this direction. Here I must notice the course of 

 public lectures at the George Herdman Institute which 

 Mr. Bruce is arranging at the beginning of 1922. 



A detailed list of the workers at the Station is given in 

 the " Curator's Report."
