Bureau in order' to obtain exact determinations of the species. The Biological De- 

 partment should then send these on to the experts concerned, obtain the desired 

 determinations and return the determinations and samples to the naturalists. This 

 proposal was accepted. 



In accession thereto it was set forth that it would be desirable to make 

 exact investigations of some of the most important plankton species, especially cer- 

 tain Copepods, with exact determination of the different stages of development, 

 their horizontal and vertical distribution and quantity. Such investigations should 

 be carried out by means of closing nets of the finest silk gauze (no. 25, old no. 20). 



It would be specially desirable to make thorough biological investigations of 

 such species which are of importance as fish-food. It was also desirable, therefore, 

 to investigate the stomach contents of pelagic fishes and fish-larvae as well as the 

 plankton in the surrounding water. 



For the study of microplankton it is recommended to employ the method 

 mentioned by Prof. Gran in his lecture, viz. to investigate the plankton of samples 

 taken with water bottles at different depths. By adding Flemming's solution to the 

 water sample examination of the plankton could be made later in the laboratory, 

 not necessarily onboard. 



The discussion of these proposals was not finished, but was postponed till 

 the next meeting. 



Third Sitting: Friday 26th April 1912. 



Chairman: Prof. Brandt. 



Present: Messrs. Archer, Kramp, Kyle, Ostenfeld, Paulsen, Pettersson, Witting. 



After the last meeting the plankton specialists had further discussed the 

 proposals for the future work and agreed upon the considerations and the pro- 

 posals for the resolutions. They were read aloud by Prof. Brandt and agreed to 

 by the meeting. 



The proposals for the resolutions were given over to the Bureau. 



The considerations for the future work are as follows: 

 1. The investigation with plankton nets (of the finest silk) should — in 

 addition to carrying out the ordinary purposes of the plankton investigations — 

 chiefly aim at acquiring knowledge of the various stages in the life history of
