COURSE OF INSTRUCTION ON OCEAN RESEARCH. 



IT is intended this year, as previously, to give a course of instruction in Bergen, from August S to October 14, on Ocean 

 Research. 

 This will consist partly of lectures, partly of practical instruction and assistance in laboratory work ; excursions will also 

 be made, during which the use of various appliances and instruments will be practically demonstrated. All pupils must, however, 

 bring microscopes and magnifying glasses. 



Each student is charged a fee of about four guineas (Kr. 75.00). Special pupils who desire to continue their studies after 

 the conclusion of the regular course are permitted to do so, and are not required to pay any additional fee.

of the bottom and upon hydrographical conditions.
