PRACTICAL MICROSCOPF. 



(vide Fig. 6), make the cut precisely as in free-hand cutting. The- 

 section is then brushed off into the saucer, the screw turned up 

 slightly, the razor wetted, and a second cut made. These steps are 

 repeated until the required number of sections has been obtained. 



FIG. 6. METHOD OP CUTTING SECTIONS WITH THE STIRLING MICROTOME. 



The imbedding will leave the cuts as they are floated in the alcohoL 

 They may now be selected, lifted with the needle into clean spirit^ 

 and preserved as before indicated, for future operations. 



THE SCHRAUEE MICROTOME. 



Fig. 7 represents an improvement on the Stirling instrument, and 

 a most convenient, practical and inexpensive microtome for the phy- 

 sician. 



FIG. 7. SCHRAUER'S IMPROVED STIRLING MICROTOME, 

 With clamp for holding the tissue. 



The tissue, if sufficiently hard, is held in a clamp or vice in the 

 well of the instrument, the pressure being regulated by the side 

 screw. By this means the necessity of imbedding is avoided. If the
