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.
