thorax (the dissection is best done on a dull-black 

 surface). 



4. Examine the piece of tissue under a half-inch 

 lens. (The diaphragm should be as nearly closed as 

 possible). The glands will be seen hanging on to the 

 neck as finger-like, transparent, glistening bodies. 

 Muscle has a greyish look, and even the fat body is 

 not so refractive as the glands.

5. Now place one needle on the head, and with 

 the other make a transverse cut between the head and 

 the attached portion of the glands. 



6. Examine again the now separated glands. 

 Generally all six are with certainty got in this way. 



7. If the glands are not found on the neck, 

 proceed with the dissection by Method 2. 



8. When dissected out in this way, they are 

 generally quite free from surrounding tissues, but if 

 found necessary they can be teased out further and 

 placed in fresh drops of salt solution.
