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

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.
