652 KEPORT OF THE COUNCIL. 



in the laboratory, all the species of animals and plants they contain 

 being recorded, and the abundance of each indicated according to 

 the system adopted by the International Council. 



II. Intermediate Observations. 



Arrangements are being made for obtaining frequent observations of 

 surface temperature and samples of surface water and plankton from 

 lightships round the coast, as well as from steamers running along 

 certain routes. These observations will be extended as far to the 

 westward and north-westward as possible. 



The regular station work will be carried out as frequently as possible, 

 in the intervals between the seasonal cruises, at one or two stations at 

 the western end of the English Channel. 



B. WORK ALREADY ACCOMPLISHED. 



All the stations set forth above were worked during the first 

 fortnight of February (1903) with the steamer Huxley, and a complete 

 set of observations and samples obtained from each. The salinity of 

 all the water samples has since been determined, and a record of these 

 and of the other observations made has been forwarded to the Central 

 Bureau at Copenhagen for publication in the International Bulletin. 



The samples of plankton collected have been qualitatively examined, 

 and the species, more especially of Diatoms, Peridinidae, and Copepoda, 

 determined in all cases. These results will also be forwarded to the 

 Central Bureau for publication. 



A similar series of observations was carried out during the first 

 fortnight of May.
