Mr. Thorild Wulff of the University of Lund collected 

 during a voyage, September 1902 to February 1903, to and 

 from Bombay a series of samples of plankton, which were 

 delivered to me for examination. All the samples had been 

 obtained by filtering water from the pump of the steamer 

 through a fine silk-net. In the same time the samples were 

 collected the temperature of the water was noted and samples 

 of water bottled for chemical examination. The latter samples 

 were tested for chlorine by Miss A. Palmquist. 



The following lists indicate the stations, where the samples 

 had been collected. The temperature of the water in centi- 

 grades is to be found under the head Temp., the salinity in 

 »pro mille» under Sal. I have under the heads Pn qt, Pn ql, 

 and NS. noted the quantity (c large, + median, r sparingly, 

 and o no plankton) the quality (Cp, copepoda, Pr, peridinales, 

 D, diatoms, ii, radiolaria and T, tintinnodea) and the number 

 of species noted.
