the sea sampler bottle very carefully, let a 

 small amount, about 15 ml., of water drain 

 into the funnel (fig. 2-19). Remove the funnel, 

 close the salinity bottle, and shake vigorously. 

 Drain the rinse water out so it washes over 

 the glass stopper and gasket and through the 

 funnel. Repeat this rinsing procedure a second 

 time. Replace the funnel in the salinity 

 bottle and pour in the remaining water. Re- 

 move the funnel and fasten the stopper tightly. 

 Great caution must be taken not to use too 

 much water in rinsing as the sea-sampler 

 bottle contains only about 125 ml. of water.
