The proper first aid for a person who has eaten metallic mercury or a
mercuric compund would be to make the person vomit.  This can be done
by triggering the emesis reflex (e.g. by sticking a finger into the
person's throat) or by giving a drug that makes the person throw up. 
A gastric lavage (removing the gut contents with a suction tube) can
also be useful, but this must be done by a doctor.

Activated charcoal, milk or raw egg whites should be given orally to
avoid absorption of mercuric compunds from the intestines.

The patient should also recieve treatment with an approperiate
chelating agent such as DMPS (the sodium salt of
2,3-dimercapto-1-propane sulfonic acid).  A chelating agent is a
chemical compound that is able to bind heavy metal salts.  The
treatment usually lasts for around three weeks.

Another chelating substance known as dimercaprol (or BAL) have been
used to treat mercury poisoning, but this practice is now discouraged.
 BAL may actually enhance passage of organic mercury compounds across
the blood-brain barrier.

The ingestion of mercury I was referring to was ingested over a long
period of time (several yrs eating contaminated fish) not for example
out of a broken therometer.

If the patient has signs of chronic mercury poisoning such as
gingivitis (inflammation of the gums), mental disturbances or
neurological deficits AND a suspected history of exposure to mercuric
compunds the same kind of treatment can be used.  The patient's
exposure to mercury can be evaluated through urine and fecal (stool)
samples.
