If there is a substance which has been previously looked
up during the current Toxicall® session, and you would like to view this list,
click the historical substance button 
. By selecting a
substance and clicking ‘OK’, the substance description, Poisindex code, and
Generic Code will be propagated into the appropriate fields as if doing a
Poisindex lookup. Clicking OK will overwrite any information in the substance
description, Poisindex code, and Generic Code fields. Clicking ‘Cancel’ will
close this window without propagating data into the substance fields.
