50 THE MICROSCOPIST. 



one end is closed with the finger a quantity of water, &c., may 

 be lifted from a phial, as seen at Fig. 20, and put in a watch- 

 glass. By their aid, too, with a little practice, an animalcula 

 may be caught in a phial, when it is visible to the naked eye. 

 With the finger on one end of the tube, approach the other 

 end to the place where the animal is, then suddenly lifting off 

 the finger, the current will carry it into the tube. 



A Compressor ium, for applying pressure to an object ; a 

 trough for chara and polypi ; a phial-holder, &c. ; will also be 

 found useful.
