DePaul Obstetrical Stethoscope
This DePaul obstetrical stethoscope was made somewhere around 1885 by
an unknown manufacturer. It was made of hard rubber, and was
very light—weighing only 1 oz. The length of the stethoscope was 5⅝".
Don't confuse stethoscopes with the shorter ear trumpets and
conversation tubes. See
General Information—Conversation Tubes for further information on
this subject.

View of the bell end of the DePaul Obstetrical stethoscope. This is the
end that went against the mother's abdomen. The large hollow bell let it
"fit" to the curve of her abdomen without rocking which let the doctor
hear the best. The bell was 2⅛" in diameter.
