Does anyone know of a source for those flat, red paraffin squares that

Diana, I believe you are talking about the dental wax sheets, available
from Ernest Fullam, Inc. order# 52410 I use them everytime I necropsy.

In response to the pneumatics tube system inquiries:
My husband was a biomed engineer that would get calls all hours of the
night to unstuff the tube that was zealously packed full of material and
therefore stuck in the system (weight factor) and stopped all operation. He
has since found a much better (pay?!) job and sleeps well 8^)
Happy Thanksgiving
