32 PRACTICAL MICROSCOPY. 



the thumb and forefinger, the linen being interposed. Very slight 

 pressure and rubbing will complete the process. The surface of the 

 glasses should be brilliant, and they are to be preserved for future use 

 in a dust-tight box. 



TRANSFERRING THE SECTIONS TO THE SLIDE. 



Procure a piece of either very thin sheet copper or heavy tin foil, 

 three inches long and one-half inch wide, and bend it about three- 

 fourths of an inch from one end, making a section lifter as shown in 

 Pig. 17. 



FIG. 17. SECTION SPOON. 



Strip of copper or heavy tin foil, best for lifting sections from staining and other fluids. For 

 use in fluids which would attack metals, the spoon should be constructed from horn. 



Place a clean slide on the table before you and with the section - 

 lifter used like a spoon dip up one of the sections from the clove-oil. 

 By inclining the lifter, the section may be made to float to the centre 

 of the slide. A small sable brush is often convenient for coaxing the 

 section off the lifter. 



If it were our present object to simply examine the section, we 

 could drop a thin cover-glass on the specimen, and it would be ready 

 for study. Such an object would afford every requirement for 

 present observation, but would nofc be permanent. The oil of cloves
