CHQ: SUBJECT: bowel movement
  MESSAGE: for the second time today I have seen matter moving as in swimming on the surface of the water after a loose bowel movement.  the first was small but today it was a larger chair or elongated mass that was moving on the surface of the still toilet water.   I thought I was seeing things the first time but this time I am sure.    what is this?
Summary: How are moving specimens in a loose bowel movement identified and treated?
